vastly underutilized as coupling partners in transition metal catalysis. Herein, we describe a copper metallaphotoredox manifold for the open shell deoxygenative coupling of alcohols with N-nucleophiles to forge C(sp3)–N bonds, a linkage of high value in pharmaceutical agents that is challenging to access via conventional cross-coupling techniques. N-heterocyclic carbene (NHC)-mediated conversion of
醇类是最丰富的化学原料之一,但它们作为过渡金属催化的偶联伴侣仍未得到充分利用。在本文中,我们描述了一种铜金属光氧化还原歧管,用于醇与 N 核试剂的开壳脱氧耦合以形成 C(sp3)-N 键,这是一种在药物剂中具有高价值的键,难以通过传统的交叉偶联技术获得。N-杂环卡宾 (NHC) 介导的醇转化为相应的烷基自由基,然后是铜催化的 C-N 偶联,使该平台成功地用于广泛的结构无偏性醇和 18 类亲核试剂。
