Phthalate esters have been widely used in industrial nations as plasticizers, in cosmetics, insect repellants, and munitions (Ribbons et al., 19847 Peakall, 1975). Due to the abundance of plastic materials in use, it has been estimated that 51 million pounds of phthalate esters leach into the environment annually (Ribbons et al., 1984). Phthalate esters have been found in many environmental sam...

Increases in activity of both protein kinase A (PKA) and protein kinase C (PKC) contribute to short-term facilitation of Aplysia sensorimotor synapses evoked by serotonin (5-HT). We report here that increasing levels of cAMP in sensory neurons evokes increases in both synaptic efficacy and in the number of sensory neuron varicosities contacting the major axons of motor cell L7 at intermediate t...

barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. their reduction with zinc and hydrochloric acid in methanol yielded the narylmethylcysteines ?9a-c?. these can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?reaction of n, n'-carbonyl diimidazole (im co...

Asymmetric addition of arylboroxines to β-alkoxyacrylate esters proceeded in the presence of a rhodium complex coordinated with a chiral diene ligand to give high yields of β-alkoxy-β-arylcarboxylic acid esters with very high enantioselectivity.

N-Hydroxysuccinimide esters of long-chain fatty acids have been used to synthesize the CoA and thioglycolic acid thiol esters of palmitic and 3-ketopalmitic acids in high yield and with a minimum of untoward side reactions.

This paper describes an efficient asymmetric biomimetic transamination of α-keto esters with a quinine-derived chiral base as the catalyst, giving a variety of β-branched α-amino esters in 50-96% yield and 87-95% ee.
