An efficient NH4I-mediated intermolecular annulation of methyl N-heteroaromatics with amines/amino acids was developed by virtue of anodic oxidation, providing a variety of functionalized imidazo-fused N-heterocycles with good to excellent yields. The practicality of this protocol was demonstrated by the readily available starting materials, broad substrate scope, water tolerance, scalability, and
通过阳极氧化,开发了一种有效的NH 4 I介导的甲基N-杂芳族化合物与胺/氨基酸的分子间环化反应,提供了多种具有良好至优异收率的官能化的咪唑并合的N-杂环。该协议的实用性通过容易获得的起始材料,广泛的底物范围,耐水性,可扩展性以及电解产物的多种转化得到证明。
