摘要：

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 reasonable yields. The copper ferrite is easily recovered and reused, up to nine times without a significant yield loss.
