A method for the C-N coupling of imidazoles based on electrooxidative C-H functionalization of aromatic and benzylic compounds has been developed. The key to the success is the formation of protected imidazolium ions as initial products, avoiding overoxidation. Deprotection under nonoxidative conditions affords N-substituted imidazoles. Various functional groups are compatible with the present transformation
已经开发了一种基于芳香族和苄类化合物的电氧化 CH 官能化的咪唑 CN 偶联方法。成功的关键是形成受保护的咪唑鎓离子作为初始产物,避免过度氧化。在非氧化条件下脱保护得到 N-取代的咪唑。各种官能团与本转化相容。为了证明该方法的功效,合成了 P450 17 抑制剂和具有 N-取代咪唑结构的抗真菌剂。
