An efficient and mild protocol was realized using 1,2‐diazoles and related heterocycles with cyclic and acyclic enones in presence of T3P (2,4,6‐tripropyl‐1,3,5,2,4,6‐trioxatriphosphorinane‐2,4,6‐trioxide) toward the regioselective formation of N‐cycloalkyl heterocycles at room temperature. The developed reaction conditions showcased good selectivity over a wide range of 1,2‐diazoles and enones by
在存在T3P(2,4,6-三丙基-1,3,5,2,4,6-三氧三磷酸正膦2, 4,6-三氧化物)在室温下朝向N-环烷基杂环的区域选择性形成。发达的反应条件通过以极高的产率提供N-环烷基杂环,在1,2-二唑和烯酮中显示出良好的选择性。
