N-alkyl formamide activation by using of copper/oxidant system via tandem/domino reaction pathway to construct C−N/C−O bond formation is reported. This protocol elucidated a method for the synthesis of pharmaceutically interested 3-alkyl-1,3-benzoxazine-2,4-dione and 1,3-methylene-3-alkyl-benzoxazine-2-one derivatives without the aid of toxic chemicals such as phosgene or its derivatives.
报道了使用铜/氧化剂系统通过串联/多米诺反应途径活化N-烷基甲酰胺以构建 C-N/C-O 键的形成。该协议阐明了一种在没有有毒化学物质的帮助下合成药学上感兴趣的 3-烷基-1,3-苯并恶嗪-2,4-二酮和 1,3-亚甲基-3-烷基-苯并恶嗪-2-酮衍生物的方法作为光气或其衍生物。
