facilitated by the electrophilic nature of these open-shell intermediates and the presence of strong polar effects in the transition-state for C-N bond formation/ring-opening. With the aid of a simple reductive quenching photoredox cycle, we have successfully harnessed this novel radical strain-release amination as part of a multicomponent cascade compatible with several external trapping agents. Overall, this
在此,我们报告了用于官能化双环[1.1.1]
戊胺的不同制备的光催化策略的发展。该方法首次利用氮自由基与[1.1.1]
丙烷进行应变释放反应的能力。这些开壳层中间体的亲电子性质以及 CN 键形成/开环过渡态中强极性效应的存在促进了这种反应性。借助简单的还原猝灭光氧化还原循环,我们成功地利用这种新型自由基应变释放胺化作为与多种外部捕获剂兼容的多组分级联的一部分。总体而言,这种激进的策略能够快速构建新型
氨基功能化结构单元,并在药物
化学项目中具有潜在的应用前景,如对位取代
苯胺生物等排体。
