Abstract

(Chemical Equation Presented) A method for direct, stereoselective preparation of (E)-α,β-unsaturated ketones from ketones and aldehydes, promoted by a novel pyrrolidine imide organocatalyst, has been developed in moderate to high yields. Unlike the Claisen-Schmidt condensation and Lewis acid catalyzed tandem aldol-dehydration processes, this method provides mild reaction conditions to access α,β-unsaturated ketones from simple, unmodified ketones.
