A protocol for the preparation of 7-amido indoles via regioselective C–H bond functionalization has been first accomplished under Ru(II) catalysis. Indole derivatives and 4-aryl/heteroaryl/benzyl/alkyl dioxzaolines containing various substituents were applicable for this transformation, readily providing the amidated indoles in moderate to good yields. This novel process has many advantages, including
通过Ru(II)催化首先完成了通过区域选择性C–H键官能化制备7-氨基吲哚的方案。含有各种取代基的吲哚衍生物和4-芳基/杂芳基/苄基/烷基二恶唑啉可用于该转化,容易地以中等至良好的产率提供酰胺化的吲哚。这种新颖的方法具有许多优点,包括与各种官能团的良好相容性,广泛的底物范围和温和的反应条件。已经进行了氘代研究和对照实验以了解这种转化的机理。
