  simple route towards the synthesis of hindered ethers, in which electrochemical oxidation is used to liberate high-energy carbocations from simple carboxylic acids. These reactive carbocation intermediates, which are generated with low electrochemical potentials, capture an alcohol donor under non-acidic conditions; this enables the formation of a range of ethers (more than 80 have been prepared here)

  受阻醚在各种应用中都具有很高的价值；然而，它们仍然是未充分探索的化学空间领域，因为它们难以通过常规反应合成 1,2。这种基序在药物化学中非常令人垂涎，因为对醚键的广泛取代可以防止可能导致体内快速降解的不需要的代谢过程。在这里，我们报告了合成受阻醚的简单途径，其中电化学氧化用于从简单的羧酸中释放高能碳正离子。这些反应性碳阳离子中间体以低电化学势生成，在非酸性条件下捕获醇供体；这使得能够形成一系列醚（这里已经制备了 80 多种），否则很难获得。碳正离子也可以被简单的亲核试剂拦截，导致受阻醇甚至烷基氟化物的形成。评估该方法能够规避制备 12 种化学支架时遇到的合成瓶颈，从而提高所需产品的产率，此外还显着减少了制备所需的步骤数量和劳动量。分子探针的使用和动力学研究的结果支持了所提出的机制和添加剂在所检查条件下的作用。我们在这里报告的反应流形证明了电化学在温和条件下获得高反应性中间体的能力，反过来，
