摘要

Reduction of some diketones and a ketoacid with yeast, Pichia farinosa IAM 4682 was examined. The reduction of carbonyl groups proceeded highly selectively with an anti- Prelog fashion to give (R)-alcohols.(2R, 5R)-2, 5-Hexanediol (83% yd.,> 99% ee, 95% de),(2R, 4R)-2, 4-pentanediol (94% yd.,> 99% ee, 98% de), and (R)-4-pentanolide (67% yd.,> 99% ee) were highly efficiently obtained from the corresponding ketones. Effect of ...
