The synthesis and some reactions of 2,3-substituted 1-phenylbenzo[f]quinoline

A series of 2,3-substituted 1-phenylbenzo[f]quinolines was synthesized by the Friedlander condensation of 1-benzoyl-2-naphthylamine with β-keto esters. Some chemical transformations of these compounds and the preparation of 13H-benzo[f]indeno[2,1-c]quinoline-13-one and its 9-methyl derivative are described.
