A versatile and efficient method for the coupling of maleimides and indoles at the C7-position has been established under Rh(III) catalysis. The present protocol was compatible with various functional groups, diverse 3-(indol-7-yl)maleimides and 3-(indol-7-yl)succinimides were obtained in moderate to excellent yields by switching reaction conditions. Moreover, this method further highlights the unique
在 Rh(III) 催化下,建立了一种在 C7 位偶联马来酰亚胺和吲哚的通用且有效的方法。本协议与各种官能团兼容,通过切换反应条件以中等至优异的产率获得了多种 3-(indol-7-yl)maleimides 和 3-(indol-7-yl)succinimides。此外,该方法进一步突出了与药用化合物和氨基酸衍生物结合的独特实际应用。为了探索这种转化的机制,已经进行了氘化研究和对照实验。
