N-(benzoazynyl) aminides with N-halosuccinimides provides a mild and regioselective method to functionalize the negatively charged diazine moiety in most cases. In some examples, however, formation of other products is explained. Finally, alkylation of the exocyclic nitrogen and reduction of the N–N bond provides a simple and straightforward strategy to obtain functionalized N-benzyl-benzoazynyl-α-amines.
在大多数情况下,用N-卤代琥珀酰亚胺卤化吡啶鎓N-(苯并炔基)氨基化物提供了温和的区域选择性方法,以使带负电的二嗪部分官能化。但是,在某些示例中,将解释其他产品的形成。最后,环外氮的烷基化和N–N键的还原为获得官能化的N-苄基-苯并炔基-α-胺提供了一种简单明了的策略。
