New types of phototransformations in the quinone series, viz., photocyclizations of 1-aryloxy-2-azido-9,10-anthraquinone in the presence of phenols, were studied. The photolysis affords mainly 5H-naphtho[2,3-c]phenoxazine-8,13-diones, in which the nitrogen atom is covalently bound to the phenyl ring of the attached phenol. As a result, complex polycyclic derivatives of phenoxazines were prepared in high yields in one step.
研究了醌系列的新型光转化,即 1-芳氧基-2-叠氮-9,10-蒽醌在苯酚存在下的光环化。光解主要产生 5H-萘并[2,3-c]吩嗪-8,13-二酮,其中的氮原子与所附苯酚的苯基环共价结合。因此,只需一步就能以高产率制备出复杂的吩噁嗪多环衍生物。
