The reduction of 3-benzoyloxy-1-hydroxypropanone with bakers' yeast proceeds enantioselectively to afford (S)-3-benzoyloxy-1,2-propanediol, which may be further converted into (S)-(benzoyloxymethyl)oxirane. The bioreduction with fermenting yeast of 1-acetoxy-3-benzyloxypropanone gives (R)-1-benzyloxy-3-acetoxy-2-propanol which can be used for the preparation of both (S)- and (R)-1,2-O-isopropylideneglycerol.
3-苯甲氧基-1-羟基丙酮与酵母的还原反应具有对映选择性,生成(S)-3-苯甲氧基-1,2-丙二醇,该产物可以进一步转化为(S)-(苯甲氧基甲基)氧杂环丙烷。用发酵酵母对1-乙酰氧基-3-苄氧基丙酮进行生物还原可得(R)-1-苄氧基-3-乙酰氧基-2-丙醇,后者可用于制备(S)和(R)-1,2-O-异丙基氘醇。
