Substituted and unsubstituted naphthylamines were transformed into the corresponding triazole derivatives, which were converted to dimethyl 1H-benz[g]indole-2,3-dicarboxylates by photocyclization. The reaction of the diesters with hydrazine hydrate gave the corresponding 8,9-dihydrobenzo[g]pyridazino[4,5-b]indole-7,10(11H)-diones (5). One of compounds 5 was found to have chemiluminescent activity similar to luminol.
