A rhodium(III)-catalyzed intermolecular C–H amination of ketoxime and iodobenzene diacetate-enabled N–N bond formation in the synthesis of indazoles has been developed. A variety of functional groups were well tolerated, providing the corresponding products in moderate to good yields. Moreover, the nitro-substituted ketoximes are well compatible in this reaction, leading to the corresponding products
在吲哚合成中,铑(III)催化了酮肟的分子间CH-H胺化反应和碘代苯二乙酸酯使N-N键形成。各种官能团的耐受性良好,可提供中等至良好收率的相应产物。此外,硝基取代的酮肟在该反应中具有良好的相容性,从而以中等至良好的收率得到相应的产物。
