A practical two-step synthesis of 2,3-dihydropyrroles from Ugi 4-CR/propargyl adducts is presented. The protocol includes a base-mediated formation of an allenamide functional group and an in situ metal-free formal 5-endo cycloisomerization that occurs in a highly regioselective manner at the allenamide C-γ.
