• chiral
  • To date, all practical methods for the preparation of chiral a-sulfenylated aldehydes have been multistep procedures that involve chiral auxiliaries. (docme.ru)
  • Asymmetric Catalysis Enantioselective Organocatalyzed a Sulfenylation of Aldehydes** Mauro Marigo, Tobias C. Wabnitz, Doris Fielenbach, and Karl Anker Jørgensen* Optically active a-heterosubstituted aldehydes are versatile building blocks for the synthesis of chiral molecules that bear heteroatom functionalities. (docme.ru)
  • Formaldehyde
  • Aldehydes (except those without an alpha carbon, or without protons on the alpha carbon, such as formaldehyde and benzaldehyde) can exist in either the keto or the enol tautomer. (wikipedia.org)
  • This word can be recognized in the simplest aldehyde, formaldehyde, and in the simplest carboxylic acid, formic acid. (wikipedia.org)
  • Smaller aldehydes are more soluble in water, formaldehyde and acetaldehyde completely so. (wikipedia.org)
  • The two aldehydes of greatest importance in industry, formaldehyde and acetaldehyde, have complicated behavior because of their tendency to oligomerize or polymerize. (wikipedia.org)
  • Aldehyde Ferredoxin Oxidoreductase is a member of an AOR family, which includes glyceraldehyde-3-phosphate ferredoxin oxidoreductase (GAPOR) and Formaldehyde Ferredoxin Oxidoreductase. (wikipedia.org)
  • anion
  • The Vanderwal group has also reported the synthesis of 4-stannyldienals from Zincke aldehydes by addition of tributylstannyl anion and quenching with acetyl chloride. (wikipedia.org)
  • NADPH
  • Dihydroflavonol 4-reductase uses sinapaldehyde or coniferyl aldehyde or coumaraldehyde and NADPH to produce sinapyl alcohol or coniferyl alcohol or coumaryl alcohol respectively and NADP+. (wikipedia.org)
  • acetaldehyde
  • The main substrates for aldehyde ferredoxin oxidoreductase are acetaldehyde, phenylacetaldehyde, and isovalerdehyde, which is a metabolic product from common amino acids and glucose. (wikipedia.org)
  • Organic
  • An aldehyde /ˈældɪhaɪd/ or alkanal is an organic compound containing a functional group with the structure −CHO, consisting of a carbonyl center (a carbon double-bonded to oxygen) with the carbon atom also bonded to hydrogen and to an R group, which is any generic alkyl or side chain. (wikipedia.org)
  • Aldehydes are common in organic chemistry. (wikipedia.org)
  • group
  • To provide for facile product elaboration, S-benzyl-protected a-sulfenylated aldehydes were chosen as synthetic targets, as there are well-established methods for the cleavage of this protecting group. (docme.ru)
  • Related to (i), the aldehyde group is somewhat polar. (wikipedia.org)
  • If replacing the aldehyde group with a carboxyl group (−COOH) would yield a carboxylic acid with a trivial name, the aldehyde may be named by replacing the suffix -ic acid or -oic acid in this trivial name by -aldehyde. (wikipedia.org)
  • In 2009, the Vanderwal group reported another interesting rearrangement of Zincke aldehydes. (wikipedia.org)
  • The nomenclature is derived from the nomenclature of the alkanes, the ending -al is added to indicate the aldehyde group. (wikipedia.org)
  • Polyunsaturated aldehydes (PUAs) are a group of allelopathic chemicals typically associated with diatom-copepod predator-prey interactions. (wikipedia.org)
  • The aldehyde tag is a short peptide tag which can be introduced into fusion proteins and by subsequent treatment with the formylglycine-generating enzyme (FGE) a reactive aldehyde group is generated for further coupling. (wikipedia.org)
  • A carbonyl group is introduced into proteins as a chemical reporter using different techniques, including modern methods like stop codon suppression and the herein discussed aldehyde tag. (wikipedia.org)
  • This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. (wikipedia.org)
  • synthetic
  • Nouvelle méthode générale synthétique de préparation des aldéhydes" [Novel general synthetic method for preparing aldehydes]. (wikipedia.org)
  • reactive
  • Since there already is an array of aldehyde-specific reagents commercially available (such as aminooxy or hydrazide reagents), possible applications are diverse and include the conjugation of fluorophores, glycans, PEG (polyethylene glycol) chains or reactive groups for further synthesis (see applications). (wikipedia.org)
  • addition
  • Upon addition of a N,N-disubstituted formamide (such as DMF) a hemiaminal is formed, which can easily be hydrolyzed into the desired aldehyde. (wikipedia.org)
  • processes
  • Zuschriften aldehydes and the merits of organocatalytic processes, which circumvent the undesired association of sulfur reagents with metal catalysts. (docme.ru)
