An efficient and high-yielding, one-pot, Cu-catalyzed synthesis of 2-indolyl-C-glycosides is delineated. The sequence involves a cascade Sonogashira type coupling and a hydroamination reaction between sugar-derived alkynes and N-tosyl-o-iodoaniline followed by removal of the N-tosyl group to provide a library of 2-indolyl-C-glycosides in moderate to excellent yields.
描述了一种高效且高产的单锅 Cu 催化合成 2-吲哚基-C-糖苷。该序列涉及级联 Sonogashira 型偶联和糖衍生的炔烃和 N-甲苯磺酰基-邻碘苯胺之间的加氢胺化反应,然后去除 N-甲苯磺酰基,以提供中等至优异的 2-吲哚基-C-糖苷库产量。
