β-Lactam scaffolds are considered to be ideal building blocks for the synthesis of nitrogen-containing compounds. A new palladium-catalyzed oxidative carbonylation of N-allylamines for the synthesis of α-methylene-β- lactams is reported. DFT calculations suggest that the formation of β-lactams via a four-membered-ring transition state is favorable.
