Optically stable thiosulphinate S-esters: asymmetric synthesis and nucleophilic substitution at sulphinyl sulphur
Abstract
Optically stable thiosulphinate S-esters containing the t-butylthio-group have been prepared by the asymmetric condensation of sulphinyl chlorides with achiral thiols in the presence of optically active tertiary amines; they have been converted into sulphoxides, sulphinamides, and sulphinates.
