palladiumTransition-metal-catalyzed alkenylation of enolates provides a direct method to synthesize broadly useful 尾,纬-unsaturated carbonyl compounds from the corresponding carbonyl compound and alkenyl halides. Despite being reported in the early seventies, this reaction class saw little development for ...

A three-component palladium-catalyzed reaction sequence has been developed in which gamma-substituted alpha,beta-unsaturated products are obtained in a single flask by an alpha-alkenylation with either a subsequent gamma-alkenylation or gamma-arylation of a ketone enolate. Coupling of a variety of ...
