Direct C-2 amidation of indoles was reported using sulfonyl azides as the amino source to release N2 as the single byproduct. This reaction exhibits high functional group tolerance and regioselectivity, providing a variety of 2-amino substituted indoles in high to excellent yield. The procedure is robust, reliable, and compatible with water and air.
直接在吲哚上进行C-2酰胺化反应,使用了磺酰叠氮作为氨基来源,并释放氮气作为唯一的副产物。该反应表现出高度的官能团容忍性和区域选择性,能够以高至极佳的产率提供多种2-氨基取代的吲哚。此过程稳健、可靠,并且与水和空气兼容。
