Abstract

Abstract: A new type of enzymatic hydrolysis, enantioface-differentiating hydrolysis of enol esters, is disclosed. As a result of screening, Pichia miso IAM 4682, a type of yeast, was selected as the best strain to perform the enantioselective hydrolysis of enol esters to give a- chiral ketones. For example, incubation of 1-acetoxy-2-methylcyclohexene (4a) with P. miso afforded (S)-2-methylcyclohexanone (5) in high optical yield. This enzymatic hydrolysis is ...
