[GRAPHICS]A variety of heterocyclic ring systems can be prepared by subjecting N-aryl-substituted 5-amido-1,3-dioxins to Lewis acids. The reactions proceed via catalyzed retrocycloadditions to afford 2-amidoacroleins and concomitant regioselective electrophilic aromatic substitution reactions. The transformation is also successful using dioxins with amides that are within the incipient ring to afford the analogous lactams.
