Syntheses and Reactions of Diazepinoquinolines

Guendel, Wolf-H.,Bohnert, Sabine

, p. 769 - 777 (2007/10/02)

Three routes for the preparation of diazepinoquinolines (1) have been studied.The best yields resulted by starting from the amides of N-(3-quinolylcarbonyl)-N-alkyl-amino acids (5).Quaternization to 9, intramolecular cyclization under the influence of base to 10, oxidation to 11 and debenzylation by catalytic hydrogenation gave 1. - Keywords: Quinolinium Salts, Cyclization Reaction
