- 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.
