Cascade Michael-Aldol reaction: Efficient annulation of sulfonamide chalcones into novel cyclohexenones under solvent-free conditions

A simple, convenient and efficient synthesis of novel sulfonamide cyclohexenones from differently substituted sulfonamide chalcones has been developed. Syntheses of cyclohexenones have been achieved via cascade Michael-Aldol reaction under solvent free condition. This process features mild and solvent-free synthesis of the titled compounds with high yields (18 examples, up to 95% yield). The synthesized scaffold is a promising intermediate for the further transformation into various heterocyclic compounds.
