ChemInform Abstract: Intramolecular Alkylation of an α-Sulfinyl Vinylic Carbanion without Loss of Optical Purity: A Novel Access to Chiral Cyclic Vinylic Sulfoxides.

Abstract

Novel cyclisation via intramolecular α-alkylation of vinylic sulfoxides was studied and cyclic vinylic sulfoxides of various ring sizes (5–7) were synthesised from both (E)- and (Z)-isomers without loss of optical purity.
