two-atom subunit, is developed. The reaction takes place under mild conditions and produces a broad array of polysubstituted pyrroles in medium to high yields. It represents the first example of oxidative radical addition to imines, thus offering a new choice for the direct C–H functionalization of imines.
开发了一种银催化的正式[3 + 2]环加成反应,其中环丙醇为C3亚基,亚胺为两个原子亚基。该反应在温和的条件下进行,并以中等至高产率产生各种各样的多取代的吡咯。它代表了亚胺氧化自由基加成的第一个例子,从而为亚胺直接CHH功能化提供了新的选择。
