摘要

Abstract The amination of 2-nitroquinizarine using hydroxylamine gives 2-amino-3- nitroquinizarine, which, upon reduction, gives previously unreported 2, 3- diaminoquinizarine, a key intermediate in the synthesis of heterocyclic analogs of 5, 12- naphthacenequinone, namely, 4, 11-dihydroxyanthra [2, 3-d] imidazole-5, 10-dione (imidazoloquinizarine), 4, 11-dihydroxyanthra [2, 3-d][1, 2, 3] triazole-5, 10-dione ( ...
