Heterocyclic fused -methylene -lactams were successfully synthesized by a post-Ugi In-III-catalyzed intramolecular addition reaction. Switching from InCl3 to AlCl3 led to the regioselective synthesis of ,-unsaturated -lactams. Moreover, replacing terminal alkynes by substituted alkynes in the Ugi adducts resulted in the exclusive formation of -lactams with both catalytic systems.
