Electrophilic indole? Indoles, which are typically nucleophilic, can be made electrophilic through gold catalysis. By using an ortho‐azido group to deliver a nitrene intramolecularly, an arylalkyne is converted into a gold carbene intermediate containing an indole skeleton that is highly electrophilic at the 3‐position. A range of functionalized indoles is readily accessed by utilizing this strategy
亲电吲哚?吲哚通常是亲核的,可以通过金催化变成亲电子的。通过使用邻叠氮基团在分子内传递氮宾,芳基炔被转化为金卡宾中间体,该中间体含有在3位具有高度亲电性的吲哚骨架。利用这种策略可以很容易地获得一系列功能化吲哚。
