A method for the catalyst-free synthesis of pyrroloquinolinediones and quinolinedicarboxylates is developed through a one-pot synthesis involving denitrogenation of azide, benzisoxazole formation, aza-Diels-Alder cycloaddition, and dehydrative aromatization. Only stoichiometric amounts of N2 and H2O are produced as by-products. A comprehensive green chemistry metrics analysis indicated that this method is much more efficient and greener than two reported methods for the synthesis of pyrroloquinolinediones.

A new procedure for making 2,3-quinolinedicarboxylic acid (6), starting with aniline and maleic anhydride has been developed.Evidence for the formation of 2-anilino-3-formyl-N-phenylmaleimide (7) in the cyclization of 3-phenylimino-4-dimethylaminomethylene-N-phenylsuccinimide (4a) to N-phenylacridinimide (5a) is presented.
