Abstract
Three-component cascade condensation of 2-naphthylamine, pyridinecarbaldehydes, and 1,3-cycloalkanediones in butanol under reflux conditions was used to synthesize 11-pyridinyl-7,8,9,11-tetrahydro-10 H -benzo[ f ]cyclopenta[ b ]quinolin-10-ones and 12-pyridinyl-8,9,11,12-tetrahydrobenzo[ a ]acridin-11(7 H )-ones. Quaternary ammonium salts of a number of benzocyclopentaquinolines and benzoacridines derivatives were obtained.
