Palladium-catalyzed coupling/cyclization reactions of allene-substituted lactams

ω-(2,3-Butadienyl)lactams react with aryl iodides in the presence of n-Bu4NCl, K2CO3 and a catalytic amount of Pd(PPh3)4 to give bicyclic enamides resulting from attack of nitrogen on the central carbon and transfer of the aryl group to the terminal carbon and of the allene.
