Treatment of baker's yeast with phenacyl chloride in an aqueous–organic solvent has been proven to be an effective method of inhibiting the enzymes that afford (S)-enantiomers of α-hydroxy esters in the reduction of α-keto esters. The procedure is effective for the whole-cell system to produce the (R)-product with high chemical yield and high enantiomeric excess.
已证明在水-有机溶剂中用苯甲酰氯处理面包酵母是抑制α-羟基酯还原中提供α-羟基酯的(S)-对映异构体的酶的有效方法。该方法对于全细胞系统生产具有高化学产率和高对映体过量的(R)产物是有效的。
