An efficient asymmetric oxidation of sulfides to sulfoxides
摘要：
The Sharpless reagent (Ti(OiPr)4 + 1 mol eq. diethyl tartrate (DET) + 2 t-BuOOH) modified by addition of one mol eq. \{H2O\} gives a new homogeneous reagent which cleanly oxidizes sulfides into sulfoxides in dichloromethane. The best results were obtained for the stoichiometry Ti/DET/H2O/t-BuOOH = 1:2:1:2. The e.e. observed ranged from 4 to 93% with the highest beeing observed in the case of methyl p-toly] sulfoxide.
