A general synthetic method for the preparation of alpha,beta-unsaturated lactams starting from alkenylchloroformamides has been developed. The reaction was complete within five minutes at 150 degrees C in N-methylpyrrolidone with a catalytic amount of HBr under microwave irradiation. Not only six-membered lactams, but also five- and seven-membered lactams were obtained in high yields.
