long-standing challenge in organic chemistry. Here, we report a modular and practical alkene 1,1-carboamination technology that relies on sequential azo-ene reactions and attendant base-promoted N–N bond cleavage of azo-ene adducts with Grignard reagents. By employing allylic urazoles as imine surrogates, this method bypasses the conventional retrosynthetic logic of imine synthesis, thereby allowing for
将石化原料轻松转化为有价值的胺分子仍然是有机化学中长期存在的挑战。在这里,我们报告了一种模块化且实用的烯烃 1,1-碳化技术,该技术依赖于连续的偶氮烯反应和伴随的碱促进N - N键裂解偶氮烯加合物与格氏试剂。通过使用烯丙基 urazoles 作为亚胺替代物,该方法绕过了亚胺合成的传统逆合成逻辑,从而允许快速获得各种 α-支链烯丙基胺衍生物。
