SYNTHESIS OF DERIVATIVES OF BENZOQUINOLINES BY THE CONDENSATION OF SCHIFF BASES WITH KETONES
Unlike arylidene-1-naphthylamines, which undergo cyclization to 1-azaacenaphthene derivatives in the presence of acid, arylidene-1-naphthylamine-8-sulfonic acid adds acetophenones at the azomethine bond with the formation of arylamino ketones and their cyclization products, i.e., benzoquinoline derivatives.
