Highly Regio- and Chemoselective Palladium-Catalyzed Three-Component Assembly of Arylethylidene Malononitriles, Allylic Chlorides, and Allenylstannanes: A Novel Route to 1,7-Enyne Derivatives
An efficient method for the synthesis of 1,7-enyne derivatives via a palladium-catalyzed three-component assembly of arylethylidene malononitriles, allylic chlorides, and allenylstannanes is described.
