Multisubstituted indoles were synthesized via a one-pot tandem copper-catalyzed Ullmann-type C-N bond formation/intramolecular cross-dehydrogenative coupling process at 130 °C in DMSO. The methodology allows practical and modular assembly of indoles in good to excellent yields from readily available aryl iodides and enamines.
多取代吲哚类化合物可以通过一锅串联的铜催化的乌尔曼型 C-N 键形成/分子内交叉脱氢偶联过程,在 130°C 的 DMSO 中合成。该方法允许从易得的芳基碘化物和烯胺出发,以良好至优异的收率进行吲哚的实际和模块化组装。
