o-Nitrobenzylidene Compounds. Part 4. The Cyanide-induced Cyclisation of o-Acetamido-N-(o-nitrobenzylidene)anilines: an Improved Route to Quinoxalinocinnolines

Cyclisation of o-acetamido-N-(o-nitrobenzylidene)anilines (7) with potassium cyanide in methanol (preferably under nitrogen) leads in most cases to quinoxalinocinnolines (6) of unambiguous substitution pattern.In some cases, cyclisation appears to be incomplete, and 2-amino-3-(o-nitrophenyl)quinoxalines (11) are obtained as by-products; in certain cases quinoxalinocinnoline 5-oxides (10) are also detected.These by-products are assumed to result from oxidation of intermediates in the cyclisation process (7) ----> (6).
