  通过双 C-H 活化由偕二烷基直接合成环丙烷

  摘要：

  环丙烷是在许多生物活性分子中发现的重要结构基序，并且有许多方法可用于它们的合成。然而，在一个步骤中涉及两个 CH 键的分子内偶联的最简单的环丙烷化反应之一仍然是一个难以捉摸的转变。我们在此证明该反应可以使用芳基溴或三氟甲磺酸酯前体和 1,4-Pd 转移机制进行。发现使用新戊酸盐作为碱对于将机械途径转向环丙烷而不是先前获得的苯并环丁烯产品至关重要。化学计量机制研究允许鉴定芳基和烷基新戊酸钯，它们通过五元钯环处于平衡状态。与新戊酸盐，导致四元钯环中间体和环丙烷产物的第二次 C(sp3)-H 活化是有利的。开发了一种催化反应，并显示出生成各种芳基环丙烷的广泛范围，包括有价值的双环 [3.1.0] 系统。该方法被应用于最近批准的抗失眠药物 lemborexant 的简洁合成。

  STING (Stimulator of Interferon Genes) has become a focal point in immunology research and a target in drug discovery. The discovery of a potent human-STING agonist is expected to revolutionize current anti-virus or cancer immunotherapy. Inspired by the structure and function of murine STING-specific agonists (DMXAA and CMA), we rationally designed and synthesized four series of novel compounds for

  STING（干扰素基因的刺激物）已成为免疫学研究的重点和药物发现的目标。有望发现有效的人类STING激动剂，将彻底改变当前的抗病毒或癌症免疫疗法。受鼠STING特异性激动剂（DMXAA和CMA）的结构和功能的启发，我们合理设计和合成了四组新化合物以增强人类敏感性。在基于细胞的分析中，我们从所有合成的小分子中鉴定出六种化合物：2g，9g和12b是STING激动剂，在整个物种中均有效，并且都具有a啶酮的骨架。1b，1c和12c仅在鼠STING途径中起作用。值得注意的是，12b在六种激动剂中表现出最好的活性，其对人和鼠STING依赖性信号转导的诱导作用均与众所周知的STING诱导剂2'3'-cGAMP相似。蛋白质分析表明2 g，9 g和12b可通过直接结合人STING激活该途径，而12b也显示出最强的结合亲和力。此外，我们的研究表明，与2'3'-cGAMP相比，在天然系统中12b可以诱导更快，更

  The 1,4‐palladium shift strategy allows the functionalization of remote C−H bonds that are difficult to reach directly. Reported here is a domino reaction proceeding by C(sp3)−H activation, 1,4‐palladium shift, and amino‐ or alkoxycarbonylation, which generates a variety of amides and esters bearing a quaternary β‐carbon atom. Mechanistic studies showed that the aminocarbonylation of the σ‐alkylpalladium
