We report a method for copper ferrite-catalyzed coupling of indoles and N , N -dimethylacetamide (DMA) to afford Arundine derivatives. Halogen, methoxy, boronate ester, and trimethylsilyl functionalities are compatible with reaction conditions. Unprotected or sterically hindered indoles are also competent substrates. Indoles containing competitively reactive pyrazoles deliver the desired products in
我们报告了一种铜铁氧体催化的吲哚和 N,N-二甲基乙酰胺 (DMA) 偶联以提供 Arundine 衍生物的方法。卤素、甲氧基、硼酸酯和三甲基甲硅烷基官能团与反应条件相容。未受保护或空间位阻的吲哚也是有效的底物。含有竞争性反应性吡唑的吲哚以合理的产率提供所需的产品。铜铁氧体很容易回收和重复使用,最多可重复使用 9 次,而不会造成显着的产量损失。
