  外消旋仲烷基卤化物的对映聚合铜催化自由基 C-N 偶联获得 α-手性伯胺

  摘要：

  α-手性烷基伯胺实际上是生物、制药和材料科学中普遍存在的所有其他α-手性含氮化合物的通用合成前体。普通烷基卤与氨的对映选择性胺化对于快速获得 α-手性伯胺很有吸引力，但由于使用氨的多方面困难和不发达的 C(sp 3 )-N 偶联，迄今为止仍然很少见。在这里，我们展示了亚砜亚胺作为优异的氨替代物，用于在温和的热条件下通过铜催化与不同的外消旋仲烷基卤化物（> 60 个例子）对映聚合自由基 C-N 偶联。该反应有效地提供了高度对映体富集的N-烷基亚砜亚胺（产率高达 99% 和 >99% ee），具有仲苄基、炔丙基、α-羰基烷基和 α-氰基烷基立体中心。此外，我们已将由此获得的掩蔽 α-手性伯胺转化为各种合成结构单元、配体和具有 α-手性 N-官能团的药物，如氨基甲酸酯、羧酰胺、仲和叔胺和恶唑啉，常见的α-取代模式。这些结果揭示了对映会聚自由基交叉偶联作为一般手性碳-杂原子形成策略的潜力。

  A switchable and benign protocol for chemoselective synthesis of sulfoxides and α-alkoxy-β-ketothioethers has been developed.
