course on the type and site of substitution was found. Among the several light-induced transformations, a novel rearrangement, i.e.11 to 9 (Scheme 3) was identified. The formation of the polycyclic compound 13 on irradiation of 8a (Scheme 3) resulted from an unexpected skeletal rearrangement with dearomatization of one benzene ring. The structures of compounds 10, 11, and 13 were established by X-ray
形成在几个三环化合物的UV照射的产品(即3,6,8,15,和17,方案2-4)中详细进行了研究。发现反应过程对取代的类型和部位有明显的依赖性。在几种光诱导的转化中,鉴定了新的重排,即11至9(方案3)。辐照8a形成多环化合物13(方案3)是由于一个苯环脱芳香化而导致的意外骨骼重排。化合物的结构10,11,和13通过X-射线晶体学(建立图1-3)。试图给出所有观察到的光化学结果的一般机理图(方案4-6)。
