A facile synthesis of dibenzopyrroloazepinones via an electrophilic cyclisation of a biphenyl-acyliminium ion is described; an unusual 1,2-phenyl shift occurs when the C-1' carbon is the more nucleophilic than the C-2' carbon.
描述了一种通过联苯酰亚胺离子的亲电环化反应简便合成二苯并吡咯并氮杂卓酮的方法;当 C-1' 位碳原子比 C-2' 位碳原子更具亲核性时,会发生不寻常的 1,2- 苯基迁移。
