Abstract

An expeditious and highly diastereoselective synthesis of (Z)-2-alkylsulfenyl(or 2-cyano)-2,4-diarylthietanes 5a-i by nucleophile (CN-, RS-) induced cyclisation of O,O-diethyl S-(1,3-diaryl-3-oxopropyl) phosphorodithioates 3a-c under microwave irradiation in solvent free conditions is reported.
