enynes with N‐aryl ureas (X=NR2) and N‐vinylacetamides (X=C(O)Me), affording the corresponding 2‐alkenylindoles and 2‐alkenylpyrroles in good yield. Simple hydrogenation delivers the C2/C3‐aliphatic‐substituted indole or pyrrole (see scheme).
Rho-Rho-Rho您的小船:铑催化剂可实现烯炔与N-芳基脲(X = NR 2)和N-乙烯基乙酰胺(X = C(O)Me)的区域选择性氧化偶联,提供相应的2-烯基吲哚和2-烯基吡咯的收率好。简单的氢化作用即可得到C2 / C3脂肪族取代的吲哚或吡咯(参见方案)。
