title: A cascade reaction of pyrrole-2-carbaldehyde substituted Morita-Baylis-Hillman adducts in the presence of tetrabutylammonium hydroxide or acetate to construct aza-heterocycles.
abstract: The phase-transfer catalyst promoted intramolecular transformation of pyrrole-2-carbaldehyde substituted Morita-Baylis-Hillman adducts has been disclosed, providing an efficient way to construct pyrrolo[1,2-a]azepin-7(6H)-one skeletons in moderate to good yields (up to 92%) under mild conditions.
