The Sharpless reagent (Ti(OiPr)4 t 1 mol eq. diethyl tartrate (DET) t 2 J-BuOOH) modified by addition of one mol eq. H20 gives a new homogeneous reagent which cleanly oxidizes sulfidesinto sulfoxides in dichloromethane. The best results were obtained for the stoichiometry Ti/DET/ H20/J-BuOOH = 1:2:1

An asymmetric oxidation system using R-(+)-binaphthol as a chiral auxiliary catalyzes the oxidation of sulfides to chiral sulfoxides in good Β’nantiomeric excess ( up to 73% e.e. ) and in a high chemical yield. Although the chiral binaphthol derivatives have been used as an effective chiral auxiliar
