Heterocyclizations of 1,4-Diazido-2,3-diarylthio-9,10-anthraquinones.

-Diazidoanthraquinones of type (II) undergo stepwise thermic cyclization. Under mild conditions, the phenothiazines (III) are obtained, whereas in refluxing toluene both azido groups participate in cyclizations to give oxazolo anellated systems (IV). -(GORNOSTAEV, L. M.; LAVRIKOVA, T. I.;
