the pharmacological importance of ortho-arylbenzylamines, however, effective ortho-C-C bond formation of free primary and secondarybenzylamines using PdII remains an outstanding challenge. Presented herein is a new strategy for constructing ortho-arylated primary and secondarybenzylamines mediated by carbon dioxide (CO2). The use of CO2 with Pd is critical to allowing this transformation to proceed
通过过渡金属催化的 CH 活化形成 CC 键已成为快速制造新键的重要策略。然而,尽管邻芳基苄胺具有药理学重要性,但使用 PdII 形成游离伯胺和仲苄胺的有效邻 CC 键仍然是一个突出的挑战。本文提出了一种用于构建由二氧化碳 (CO2) 介导的邻位芳基化伯和仲苄胺的新策略。CO2 与 Pd 的使用对于允许这种转化在相对温和的条件下进行至关重要,机械研究表明它 (CO2) 直接参与速率决定步骤。此外,较温和的温度提供了无需脱保护即可直接使用或加工的游离胺产品。
