• ester
  • Preferential binding to nAChR in the absence of agonist is also seen for N , N -DEAE and N , N -diethylaminopropyl esters, both binding with 10-fold higher affinity in the absence of agonist than in the presence, and for the 4-ethoxybenzoic acid ester of N , N -diethylaminoethanol, but not for the 4-amino benzoate ester (procaine).

  • phenylacetic
  • The utility of the protocol was further demonstrated through the C3 alkylation of several substituted indole derivatives using acetic, phenylacetic or diphenylacetic acids. (rsc.org)
  • Diphenylmethane is cleaved more slowly and only to a small extent (about 1 %): the carbonated product very probably contains phenylmalonic acid, because the resulting mixture of acids is odorless at first and acquires the characteristic strong odor of phenylacetic acid only after long standing.

  • indole
  • The catalytic system based on the combination of Co(acac) 3 and 1,1,1-tris(diphenylphosphinomethyl)-ethane (Triphos, L1 ), in the presence of Al(OTf) 3 as co-catalyst, is able to perform the reductive alkylation of 2-methyl-1 H -indole with a wide range of carboxylic acids. (rsc.org)
  • 1 In fact, the essential amino acid tryptophan and the neurotransmitter serotonin contain the indole moiety in their structure. (rsc.org)
  • catalyst
  • This new protocol enables the direct functionalization of indoles with readily available and stable carboxylic acids using a non-precious metal based catalyst and hydrogen as reductant. (rsc.org)
  • reaction
  • It will not be discussed here how the phenylmalonic acid is formed, but in this connection it may be pointed out that phenylmalonic acid is also formed in the reaction of benzylsodium with carbon dioxide Tetraphenylmethane is also cleaved by potassium - actually more rapidly and more fully than 111, but the mixture of acids obtained after carbonation has a more complicated composition.
