摘要

(R, S)-1, 3-Butanediol 5 was kinetically resolved by enzymatic acetylation with vinyl acetate under the presence of Chirazyme™ L-2, c–f, yielding (S)-1-O-acetyl-1, 3-hydroxybutane 6 and (R)-1, 3-di-O-acetyl-1, 3-butanediol 7 with enantiomeric excesses of 91%(E= 67.3). Compounds 6 and 7 were easily transformed into the corresponding (S)-3-O-(2- methoxyethoxymethyl)-3-hydroxybutanal 10 and (R)-3-benzyloxybutanal 19, through a ...
