Thermal cyclization of 1,4-diazido-2,3-diarylthio-9,10-anthraquinones proceeds stepwise: the first azido group undergoes cyclization into the phenothiazine ring with participation of the arylthio group the second azido group reacts with the peri-carbonyl group with the closure of the isoxazole ring.
