A copper-catalyzed oxidative C(sp3)−H/N−H coupling of NH-heterocycles with affordable (cyclo)alkanes has been developed. This procedure involves C(sp3)−N bond formation through a radical pathway generated by homolytic cleavage of di-tert-butyl peroxide and trapping of the radical(s) by copper catalysts. The reaction tolerates a series of functional groups, such as bromo, fluoro, ester, ketone, nitrile
已经开发出铜-NH-杂环与可负担的(环)烷烃的氧化C(sp 3)-H / N-H偶联。该程序涉及通过自由基途径形成C(sp 3)-N键,该自由基途径是由二叔丁基过氧化物的均相裂解和铜催化剂捕获自由基而产生的。该反应可耐受一系列官能团,例如溴,氟,酯,酮,腈,甲基和甲氧基。游离的含NH的吲哚,吡咯,吡唑,吲唑和苯并三唑已成功进行N烷基化。
