The enantioselective reduction of ω-hydroxy-β-ketoalkyl phenyl sulfones with bakers’ yeast gives (S)-ω,β-dihydroxyalkyl phenyl sulfones, which are convenient precursors for optically active lactones as shown in the synthesis of (R)-4-hexanolide and (R)-umbelactone.
用面包酵母对 ω-羟基-β-酮烷基苯砜进行对映选择性还原得到 (S)-ω,β-二羟基烷基苯砜,如 (R)-4- 的合成所示,它们是旋光内酯的方便前体己内酯和 (R)-伞形内酯。
