Palladium-catalyzed stereoselective synthesis of (E)-β,γ-unsaturated amides

A facile Suzuki type cross-coupling reaction of alkenylborane with 2-bromo-N,N-dimethylacetamide in the presence of a catalytic amount of tricyclohexylphosphine as the ligand has been demonstrated to be a convenient way for the synthesis of (E)-β,γ-unsaturated amides.
