Syntheses of optically active γ-ketothiols and the esters by lipase-catalyzed hydrolysis via α-acetylthiomethylation of ketones
摘要:
The alpha-acetylthiomethylation of ketones was achieved by the reaction of ketones or the enamines with N,N-bis-(acetylthiomethyl)-p-chloroaniline in the presence of trifluoroacetic acid. The resulting thiolesters were hydrolyzed enantioselectively by catalysis of lipases. (C) 1997 Elsevier Science Ltd.
