The 1,5-copper-catalyzed carboamination of vinylcyclopropanes is presented. A carbon-centered radical, formed upon reduction of an alkyl halide by Cu(I), adds across the alkene of a vinylcyclopropane, triggering ring opening to generate a benzylic radical, which, finally, undergoes copper-mediated amination to afford a homoallylic amine. The reaction occurs with outstanding regio- and good to very
介绍了 1,5-铜催化的乙烯基环丙烷的碳胺化反应。 Cu(I) 还原卤代烷时形成的以碳为中心的自由基,与乙烯基环丙烷的烯烃加成,引发开环生成苄基,最后经过铜介导的胺化,得到高烯丙基胺。该反应具有出色的区域选择性和良好至非常好的非对映选择性。反应范围针对所有三种组分进行了证明:卤代烷、乙烯基环丙烷和胺亲核试剂。总共提供了 38 个示例,平均产率为 60%。
