Catalytic Asymmetric Synthesis of Atropisomeric Quinolines through the Friedl?nder Reaction

A phosphoric acid catalyzed atroposelective Friedl?nder reaction was developed in which acetylacetone and a variety of 2′-substituted 2-Aminobenzophenones were successfully employed to give optically active biaryl quinolines in good yields and with high enantioselectivities.
