    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。

The rate-limiting step of hydrolysis of 1-(4-nitrophenyl)pyrrolidin-2-one consists of the non-catalysed decomposition of the tetrahedral intermediate. In the case of 3-bromo-1-(4-nitrophenyl)pyrrolidin-2-one at sodium hydroxide concentrations below 0.1 mol l−1, the rate-limiting step is the second reaction pathway

    Reaction of 4-aminobenzonitrile with 2-bromo-4-chlorobutyryl bromide in the presence of sodium phosphate followed by treatment of the coupled product with sodium hydroxide followed by ammonium hydroxide in acetonitrile yielded the title compound as the racemic (R)-(-)-mandelic acid salt in an overall yield of 64%. The title compound was then obtained with an ee >96% and in 78% yield after a dynamic resolution of the racemic salt in IPA using a catalytic amount of salicylaldehyde followed by salt exchange.
