A convenient way to dibenzo[c,h]-1,5-naphthyridines (11-aza-benzo[c] phenanthridines)

Whereas thermal cyclisation of variously substituted 2,3-diarylacrylazides easily provided a new way to 3-aryl-isoquinolones, nitration of these compounds mainly led to corresponding 3-aryl-4-nitro-isoquinolones. After reduction into 4-amino-3-aryl-isoquinolones, amidification and subsequent cyclization gave the yet unknown title compounds.
