A method for the construction of α-methylenecyclopentenones fused to five-membered rings using a palladium catalyst is reported.The procedure involves the formation of ?-allylpalladium intermediates that undergo sequential intramolecular alkyne insertion, carbon monoxide insertion, intramolecular alkene insertion, and β-hydride elimination.Examples of the cyclization are seen in eq 2 and Scheme III.
