摘要

The stereoselective reduction of ethyl 2-(benzamidomethyl)-3-oxobutanoate 1 using yeasts was investigated among a restricted number (12) of yeasts. Kluyveromyces marxianusvar. lactis CL69 diastereoselectively produced (2R, 3S)-ethyl 2-(benzamidomethyl)-3- hydroxybutanoate 2, whereas Pichia glucozyma CBS 5766 gave (2S, 3S)-2 as the major stereoisomer. The biotransformations were independently optimized for minimizing by- ...
