Asymmetric reduction of β-ketothioester derivatives with baker's yeast produced the corresponding optically pure 3S-hydroxyethioesters, which are useful chiral building blocks in organic synthesis. The utility of the present method was demonstrated in the stereoselective synthesis of sex attractant of pine saw-fly, (2S,3S,7S)-5,7-dimethylpentadec-2-yl acetate from the SS-hydroxy esters.
用面包酵母不对称还原β-酮硫酯衍生物可产生相应的旋光纯3S-羟基硫代酯,它们在有机合成中是有用的手性结构单元。本方法的实用性在由SS-羟基酯立体选择性合成松木蝇,(2S,3S,7S)-5,7-二甲基戊二-2-乙酸基酯的性引诱剂中得到证明。
