Cascade heterocyclization of 3(4)-methylcyclohexanone, substituted benzaldehyde, and 2-naphthyl-amine in a polar solvent in the presence of hydrochloric acid afforded the corresponding 5-aryl-2(3)-methyl-1,2,3,4-tetrahydrobenzo[a]phenanthridines and 12-aryl-9(10)-methyl-8,9,10,11-tetrahydrobenz[a]acridines having an asymmetric carbon atom in position 2 or 3.
