A Chiral Br?nsted acid catalyzed asymmetric intramolecular ring-closing alkylation of inert pyrroles with α, β-unsaturated ketones has been developed. This approach gave a wide range of 4-phenyl-4,5-dihydro-6H-benzo[f]pyrrolo[1,2-a]azepin-6-ones in high yields with good enantioselectivities under mild reaction conditions. (Figure presented.).

4-Acetoxypyrroloquinolines 26-30 were synthesized by cyclization of 2-(1-pyrrolyl)phenylacetic acids 21-25 with acetic anhydride.The structures of the new compounds were determined by 1H-nmr spectroscopy.
