A one-pot synthesis of benzofurans which utilizes a palladium-catalyzed enolate arylation demonstrates broad substrate scope and provides differentially substituted benzofurans in moderate yields. The utility of the method is further demonstrated by the synthesis of the natural product eupomatenoid 6 in three steps.
