Treatment of α-(dimethylthiocarbamoylthio) ketones with bakers’ yeast afforded the corresponding chiral alcohols in high yields with high enantiomeric excess (in most cases, more than 96% ee). α-(Dimethylthiocarbamoylthio) aldehydes were reduced to give chiral α-(dimethylthiocarbamoylthio) alcohols in 69–92% yields with 32–63% ee, which were converted to chiral 1,2-epithio derivatives.
用面包酵母处理 α-(二甲基硫代氨基甲酰硫基)酮以高产率和高对映体过量(在大多数情况下,超过 96% ee)提供相应的手性醇。α-(二甲基硫代氨基甲酰硫基)醛被还原为手性 α-(二甲基硫代氨基甲酰硫基)醇,收率 69-92%,ee 为 32-63%,转化为手性 1,2-epithio 衍生物。
