Alpha-sulfanyl and alpha-selanyl propadienyl cations: regioselective generations and cycloadditions with thioamides and selemides controlled by MeNO2-H2O system.

Abstract

Alpha-sulfanyl and alpha-selanyl propadienyl cations were easily generated by the catalytic system, scandium triflate-nitromethane-H(2)O in the presence of Bu(4)NHSO(4), to regioselectively afford the multifunctionalized thiazoles and selenazoles in high yields.
