A highly efficient diversified methodology for preparation of benzimidazole, quinazolin-4(3H)-ones and 1,4-benzodiazepine-2,5-diones is established using a palladium-catalyzed transfer hydrogenation (CTH)/condensation cascade of o-nitroaniline and o-nitrobenzamides in a triethylamine-formic acid azeotropic mixture (2:5) under microwave irradiation.

In this study three new classes of linear N-tricyclic compounds, derived by condensation of the quinoline nucleus with 1,2,3-triazole, imidazole or pyrazine, were synthesized, obtaining triazolo[4,5-g]quinolines, imidazo[4,5-g]quinolines and pyrido[2,3-g]
Synthesis of two novel tricyclic rings: Triazolo[4,5-g]- quinolines and pyrido[2,3-g]quinoxalines derived from 6,7-diaminoquinolines

A general simple route for the synthesis of triazolo[4,5-g]quinolines and pyrido[2,3-g]quinoxalines is described. The heterocycles obtained were fully characterised by their spectroscopical properties. A revision of the nitration of the 2,3-dichloroacetanilide is also discussed, since it afforded the request nitro derivative to build up the key intermediate 6,7- diaminoquinolines.
