TY - JOUR. T1 - Alkali-metal-mediated zincation of anisole: synthesis and structures of three instructive ortho-zincated complexes. AU - Clegg, W AU - Dale, S H AU - Drummond, A M AU - Hevia, E AU - Honeyman, G W AU - Mulvey, R E PY - 2006/6/14. Y1 - 2006/6/14. N2 - The new concept of alkali-metal-mediated zincation (AMMZ), formally a zinc−hydrogen exchange reaction but one that requires the participation of an alkali metal, is applied here to the alkyl aryl ether anisole, an important molecule for studying directed ortho-metalation (DoM) chemistry. Treating one molar equivalent of anisole with the lithium dialkyl-TMP zincate reagent [THF·Li(μ-TMP)(μ-tBu)Zn(tBu)] (1) in hexane solution affords the mono-ortho-zincated complex [THF·Li(μ-TMP)(μ-o-C6H4OMe)Zn(tBu)] (2), which establishes that 1 functions as an alkyl base although previously it was regarded as an amido (TMP) base in other DoM applications. Treating two molar equivalents of anisole with 1, and increasing the reaction time, ...

Abstract : The objective of the present study was to evaluate the impact of biofield energy treatment on the thermal,spectroscopic, and chemical properties of anisole by various analytical methods such as gas chromatography-massspectrometry (GC-MS), high performance liquid chromatography (HPLC), differential scanning calorimetry (DSC),Fourier transform infrared (FT-IR) spectroscopy, and ultraviolet-visible (UV-Vis) spectroscopy. The anisole sample wasdivided into two parts, control and treated. The control part was remained same while the other part was treated withMr. Trivedis unique biofield energy treatment. Mass spectra showed the molecular ion peak with five fragmented peaksin control and all treated samples. The isotopic abundance ratio of 2H/1H, and 13C/12C [(PM+1)/PM] in treated samplewas increased by 154.47% (T1) as compared to the control [where, PM- primary molecule, (PM+1)-isotopic moleculeeither for 13C or 2H]. The HPLC chromatogram showed retention time of treated anisole was ...

I dont think polarization is the issue. Adding $\ce{FeBr3}$ is just to reduce the $\ce{Br-Br}$ bond strength, speeding up the reaction (attack of the aromatic ring on the bromine is part of the rate determining step, which is slow in the bromination of benzene). It functions as a catalyst being recycled when the $\ce{Br-}$ grabs a $\ce{H+}$ to restore aromaticity in the ring. Im pretty sure - at least I see no reason to doubt - that the catalyst requirements for the bromination of anisole and the bromination of phenol do not differ much, if at all. That is, no catalyst is required for the bromination of anisole.. ...

Estragole is suspected to be carcinogenic and genotoxic, as is indicated by a report of the European Union, Committee on Herbal Medicinal Products.[3] Several studies have clearly established that the profiles of metabolism, metabolic activation, and covalent binding are dose dependent and that the relative importance diminishes markedly at low levels of exposure (i.e. these events are not linear with respect to dose). In particular, rodent studies show that these events are minimal probably in the dose range of 1-10 mg/kg body weight, which is approximately 100-1000 times the anticipated human exposure to this substance. For these reasons it is concluded that the present exposure to estragole resulting from consumption of herbal medicinal products (short time use in adults at recommended posology) does not pose a significant cancer risk. In the meantime exposure of estragole to sensitive groups such as young children, pregnant and breastfeeding women should be minimized. The Scientific ...

First order-like plots, due to the large excess of methoxide, are obtained in each case, except with methyl benzoate (Plot 3) where metallic copper appeared after 1 hour (decomposition of catalyst). Slope ratio between the blank experiment (Plot 1) and the ethyl acetate one (Plot 6) is superior to 20, demonstrating the effectiveness of this co-catalyst (completion is reached within 45 min., with a quasi-quantitative yield).. Use of ethyl rather than methyl esters leads sometimes to traces of 2-ethoxy phenol (0.5 to 1%), due to releasing of ethoxide ion through transesterification of the co-catalyst by methoxide; methyl esters may therefore be preferred if highest purity of final product is required.. Anisole is also quasi-quantitatively obtained from bromobenzene in presence of ethyl acetate (10 mmole PhBr, 4 mmol EtOAc, 1,4 mmol CuBr in 6 ml 5M MeONa/MeOH, 98% conversion after 1h reflux, 100% after 2h, yield of isolated anisole >95% without detected phenetole)..

AU - Takeuchi, Masayuki. AU - Ikeda, Masato. AU - Hatano, Tsukasa. AU - Shinkai, Seiji. PY - 2002/5/13. Y1 - 2002/5/13. N2 - A novel porphyrin (1b) bearing four urea groups at its periphery was synthesized. This compound tends to aggregate into one-dimensional direction, resulting in an organogel phase in anisole and diphenyl ether solvents. The gel can be formed even at 0.125 wt/vol% in anisole and the sol-gel phase transition temperatures (Tgel) are as high as 120-140°C, indicating that 1b acts as an excellent gelator for these specific solvents. The spectroscopic studies and electron-micrographic observations support the view that the π-π stacking interaction among porphyrin moieties and the hydrogen-bonding interaction among urea moieties operate synergistically to give rise to a stable one-dimensional ...

We have studied the pyrolysis of aromatic combustion intermediates using an array of detection techniques. The molecules investigated include cyclic aromatic molecules with hydrocarbon substituents (ethylbenzene, n-propylbenzene, isopropylbenzene, and styrene), oxygen-containing substituents (anisole and phenol), triply substituted systems (vanillin), resonance stabilized radicals (benzyl radical and tropyl radical) and phenyl radical. At the exit of a resistively heated micro-reactor (1 mm inner diameter, 3 cm long), the pyrolysis fragments are detected using photoionization mass spectrometry (PIMS), matrix isolation vibrational spectroscopy, microwave spectroscopy, tunable VUV synchrotron-based PIMS, and table-top VUV PIMS with photoelectron photoion coincidence spectroscopy (PEPICO). This array of detection methods allows for the identification of all possible fragments including metastables, radicals, and atoms. The findings allow for detailed mechanistic information regarding which pathways ...

Lawessons reagent (full name 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (or -disulphide) is a chemical compound with the formula C14H14O2P2S4, used in organic synthesis as a thiation (also called thionation or sulfuration) agent. This light yellow to beige powder has a strong and unpleasant odour.. Lawessons reagent was first produced in 1956 during a systematic study of the reactions of arenes with the comparable reagent P4S10. However it was Swedish chemist Sven-Olov Lawesson who popularized Lawessons reagent within the chemical community.. Being commercially available, Lawessons reagent can also be conveniently made in the laboratory by heating a mixture of anisole with phosphorus pentasulfide until the mixture is clear and no more hydrogen sulfide is formed, and then recrystallized from toluene or xylene.. The main application of Lawessons reagent is the thionation of carbonyl compounds - the carbonyl group is converted into thiocarbonyl group, carbon-oxygen ...

The cell wall protein peptidoglycan complex (CW-PPC) ofMycobacterium tuberculosis H37Ra was isolated through sequential extraction of lipids, carbohydrates and soluble proteins. CW-PPC emulsified in FIA was found to induce significant protection in mice against challenge with LD50 dose ofM. tuberculosis H37Rv. To identify the immunoprotective components of CW-PPC, the proteins in avid association with peptidogican were dissociated by chemical treatment with trifluoromethanesulthonic acid (CF3CO3H): anisole (2:1). Immunoreactivity of total (CW-Pr) as well as its component proteins i.e., 71, 60 and 45 kDa proteins of cell wall was studied in animals immunized with CW-Pr-FIA. The 71 kDa protein was found to be most immunoreactive giving higher T-cell sensitization and humoral responses. Further, immunization of mice with 71 kDa-FIA demonstrated enhanced T- and B- cell responses. Mice immunized with 71 kDa-FIA gave significantly higher protection (P ≤ 0.05) against intravenous challenge with LD50 ...

A metabolite of beta-asarone is the reason Acurus calamus is known in some cultures as a psychedelic. However, not all Acorus calamus contains sufficient quantities of beta-asarone to be effective. Acorus calamus from Nepal typically contains a large amount of beta-asarone. Acorus calamus from India usually contains very little beta-asarone, and will cause extreme nausea before doses high enough to get some minor effects from beta-asarone are ingested.. Its important to note that beta-asarone itself is not active. One of its metabolites can produce psychedelic effects in man. Not everyones body metabolizes beta-asarone the same way, leading to different results for different individuals. Some people are not able to experience psychedelic effects from ingesting beta-asarone. This is because their bodies do not produce enough of the active metabolite to experience effects.. The active metabolite of beta-asarone is currently unidentified. There has been speculation of it being an amphetamine, ...

We have shown previously that low doses of selective sigma (sigma)- receptor ligands potentiate the excitatory response of pyramidal neurons to NMDA in the CA3 region of the dorsal hippocampus in the rat. Because progesterone competitively displaces the binding of the ligand N-[3H]allyl-normetazocine (SKF-10,047), the present studies were undertaken to determine in vivo the effect of neuroactive steroids on NMDA-induced excitation of rat CA3 pyramidal neurons. Low doses of dehydroepiandrosterone (DHEA) potentiated the NMDA response selectively and dose-dependently. The effect of DHEA was reversed by the selective sigma antagonist N-dipropyl-2-(4-methoxy-3- (2-phenylethoxy)phenyl)- ethylamine monohydrochloride (NE-100) and by haloperidol, but not by spiperone. Progesterone had no effect by itself but reversed, at low doses, the potentiation of the NMDA response induced by DHEA as well as those induced by nonsteroidal sigma ligands. Neither pregnenolone nor pregnenolone sulfate had any effect on ...

1-Methoxy-4-(2-propenyl)benzene, also known as methylchavicol or estragol, belongs to the class of organic compounds known as anisoles. These are organic compounds containing a methoxybenzene or a derivative thereof. 1-Methoxy-4-(2-propenyl)benzene is an extremely weak basic (essentially neutral) compound (based on its pKa). 1-Methoxy-4-(2-propenyl)benzene is a sweet, alcohol, and anise tasting compound. Outside of the human body, 1-Methoxy-4-(2-propenyl)benzene is found, on average, in the highest concentration within a few different foods, such as anises, fennels, and sweet basils and in a lower concentration in cumins, tarragons, and parsley. 1-Methoxy-4-(2-propenyl)benzene has also been detected, but not quantified in, several different foods, such as citrus, chinese cinnamons, caraway, fats and oils, and cloves.

Ischemic hypoxic brain injury often causes irreversible brain damage. The lack of effective and widely applicable pharmacological treatments for ischemic stroke patients may explain a growing interest in traditional medicines. β-Asarone, which has significant pharmacological effects on the central nervous system (CNS), was used in the prevention of cerebral ischemia in this paper. The right middle cerebral artery occlusion model was used in the study. The effects of β-Asarone on mortality rate, neurobehavior, grip strength, lactate dehydrogenase, glutathione content, Lipid peroxidation, glutathione peroxidase activity, glutathione reductase activity, catalase activity, Na+-K+-ATPase activity and glutathione S transferase activity in a rat model were studied respectively. β-Asarone significantly improved the neurological outcome after cerebral ischemia and reperfusion in terms of neurobehavioral function in rats. Meanwhile, supplementation of β-Asarone significantly boosted the defense mechanism

Most of the ADCs currently in the market and in clinical development carry tubulin polymerization inhibitors such as T-DM1 and SGN-35 (Brentuximab vedotin; ref. 13). We synthesized a novel ADC with a topoisomerase I inhibitor, which has a different mechanism of action from tubulin polymerization inhibitors, and a novel self-immolative linker system using an aminomethylene (AM) moiety. Although other cleavable linker systems applied to SGN-35 (Brentuximab vedotin) and several ADCs release amino group-containing payloads, this AM self-immolative linker system is able to release DXd containing the hydroxyl group from DS-8201a. Moreover, this novel linker-payload system enables a reduction in the hydrophobicity of the ADC and helps increase its DAR. In the case of T-DM1, lysine conjugation and noncleavable systems are used, and it is quite a different system from DS-8201a. DS-8201a showed potent HER2-specific efficacy both in vitro and in vivo, and by drug conjugation maintained the functional ...

N2 - The development of new antiarrhythmic agents for the treatment of atrial fibrillation is advancing simultaneously on several fronts. The molecular structure of existing agents such as amiodarone is being modified in an attempt to improve safety and reduce adverse effects. Similarly, atrial-selective antiarrhythmic drugs are being developed to minimize the occurrence of ventricular proarrhythmia. One of these atrial-selective compounds is vernakalant, which has demonstrated efficacy in terminating atrial fibrillation when given intravenously. In addition, preliminary data suggest that it could also suppress recurrences when used orally. This paper reviews the pharmacology, electrophysiology, efficacy ...

The authors of the AVRO study also assert that, while both treatments were found to be safe and well tolerated, vernakalant had low proarrhythmic potential and provides a rapidly acting therapeutic alternative.. The research team, led by Professor John Camm from St. Georges University of London, conducted a randomized, double-blind, multicenter superiority trial in 254 adult patients with underlying cardiovascular disease, making certain antiarrhythmic drugs inappropriate for use. 116 patients in each group received at least one dose of the study drug. Approximately 30% of patients in both treatment arms had no AF episodes prior to the initial diagnosis, whereas one-third had at least three..

The first indication in determining the quality of wine is if there is presence of any faults. The more common ones include cork taint (TCA) and oxidation and can be detected when an aroma or flavor in the wine appears off or just wrong. Cork taint occurs when 2,4,6 - Tricloranisole or TCA, generated by naturally-occurring fungi that often exist in the crevices of wood or cork, comes into contact with chlorine compounds present in pesticides, cleaning agents, wood treatments, etc. When cork taint occurs, the wine will have a musty, moldy aroma. Controlling the source of TCA has proven extremely difficult and currently there are no solutions.. Another wine fault is the oxidation or reduction of the wine - which happens when wines are either exposed to too much or too little oxygen respectively. When oxidation occurs, this usually results in a breakdown of its attractive color. Whites go a dull brown/straw, rosés go brown/orange, reds become paler with an orange/brown rim. Chilling grapes and ...

The present study reports densities (ρ), viscosities (η) and ultrasonic speeds (U) of pure dioxane (DOX), anisole (ANS), toluene (TOL) and ethylbenzene (ETB) and their binary liquid mixtures over the entire composition range at 293, 298, 303, 308 and 313 K. From the experimental data excess molar volume (VmE), excess intermolecular free length (LfE), excess adiabatic compressibility (βE) and excess acoustic impedance (ZE) have been computed. The excess values were correlated using Redlitch-Kister polynomial equation to obtain their coefficients and standard deviations (σ). With increase in temperature, the binary mixture of DOX+ANS shows larger deviations in βE, LfE and smaller deviations in ZE, VmE. These results suggest that ANS has strong molecular interactions with DOX than ETB and TOL.

Many would argue that the sense of smell is our far most important sense when it comes to evaluating wine. This is because the olfactory sense plays a fundamental role both in the perception of aroma and also flavour. Without it all wines,3 rather than just a few, would appear to be uninteresting alcoholic solutions of acid and sugar. The sense of smell is by far the most powerful of our senses. It can discriminate between tens of thousands of different aromas, and is capable of detecting some compounds found in wine at levels around a single part per trillion. An example of this is the compound 2,4,6 Trichloroanisole, the primary compound responsible for cork taint. Some people can detect it at around 1 part per trillion which is analogous to a single second in thirty two years. Not bad I suppose, but when you think that an Alsatian or Beagle probably sees a three dimensional colliedescope like scent world, our olfactory efforts seem pretty pathetic in comparison. The olfactory system ...

The test item consisted of non-transparent particles which had a very strong tendency for agglomeration. The particles had a sticky behaviour and were electrostatically charged after sieving. A large part of the test item was present in form of agglomerates with a diameter above 1 mm. The aforementioned effects opposed a measurement via sieve analysis and influenced the results of the study using laser diffraction. Hence, the test item was sieved with a mesh size of 1000 µm. Only 43% (w/w) of the test item passed the sieve and only this fraction was measured with laser diffraction. Median particle size D (v, 0.5): 50% of particle volume or particle mass with lower particle diameter 1st test series: 11.8 µm 2nd test series: 13.9 µm Average of median particle size: 12.8 µm Particle size D (v, 0.1): 10% of particle volume or particle mass with lower particle diameter 1st test series: 3.8 µm 2nd test series: 4.2 µm Average of the particle size: 4.0 µm Particle size D (v, 0.9): 90% of particle ...
