Abstract
The asymmetric reduction of carbonyl groups by bakers' yeast (Saccharomyces) is a well- known reaction that is widely applied for the preparation of chiral building blocks.'It has been published by many groups that a-halo ketones are easily reduced with bakers' yeast to give chiral halo hydrins. 2 Most of these studies are concerned with the reductions of 8-keto esters. Recently we reported the syntheses of chiral epoxides, key intermediates of natural ...
