Palladium-catalyzed arylation of alpha,beta-unsaturated Weinreb amides

Abstract

Palladium-catalyzed arylation of α,β-unsaturated Weinreb amides has been examined to obtain β-aryl-α,β-unsaturated Weinreb amides. The chelation between the palladium center of an alkylpalladium intermediate and Weinreb amide moiety facilitated both coordination and insertion steps.
