Enamine catalysis enables the first catalyticenantioselective Friedländer reaction. The desymmetrization of 4-substituted cyclohexanones upon reaction with o-aminobenzaldehydes allows for the synthesis of quinolines with remote stereogeniccenters. These heterocycles, which are obtained with high levels of enantioselectivity, serve as precursors for chiral tacrine analogues.
