摘　　要：为了探讨手性胶束中的不对称诱导机理，研究了手性表面活性剂及受物的结构对反应的对映体选择性影响．结果表明，表面活性剂适当位置（如铵基的α－位）有羟基存在，可得到较高的光学产率，增长表面活性剂或硫醚中烷基的链长，一般有利于手性胶束的不对称诱导．To understand the mechanistic detail of this asymmetric oxidation in chiral micelle, the oxidation of prochiral sulfide was chosen as the model reaction, the effects of structure both in substrates and surfactants on the optical yield of the oxidation were studied and discussed Results showed that increasing the alkyl chain lenghth both in surfactants and in substrates enhances the optical yield, also, the surfactant with hydroxy group at its appropriate position gives better enantio selectivity
