Photolysis of 2-amino-2′-azidobiphenyls in diethylamine gave 4,10-dihydroazepino[2,3-b]indoles (7), the structure of which corresponded to the didehydroazepines formally trapped with an internal amino group. However, the yields of 7 were considerably low, which was due to the significant intramolecular interaction of the photolytically generated nitrene with an amino group, to afford benzo[c]cinnoline as a final product.
在二乙胺中对 2-氨基-2′-叠氮联苯进行光解,可得到 4,10-二氢氮杂卓[2,3-b]吲哚(7),其结构与带有一个内部氨基的二氢氮杂卓正式化合物相对应。不过,7 的产率相当低,这是由于光解生成的腈与氨基发生了显著的分子内相互作用,最终生成了苯并[c]噌啉。
