Oxadiazolones are first employed as the three-atom coupling partners in the Tf2NH-catalyzed cycloaddition with ynamides. This formal [3 + 2] cycloaddition allows a rapid synthesis of aminoimidazoles with a broad substrate scope. The approach also features a metal-free catalytic cycloaddition process, which may find applications in the synthesis of bioactive molecules. Besides, the resulting N-methyl
恶二唑酮首先用作Tf 2 NH催化的与酰胺类的环加成反应中的三原子偶联伙伴。这种正式的[3 + 2]环加成反应可快速合成具有广泛底物范围的
