The synthesis of sterically hindered anilines has been a significant challenge in organic chemistry. Here we report a Cu-catalyzed radical addition with in situ-generated nitroso compounds to prepare sterically hindered amines directly from readily available materials. The transformation is conducted at room temperature, uses abundant copper salts, and is tolerant of a range of functional groups.
位阻苯胺的合成一直是有机化学中的一个重大挑战。在这里,我们报告了一种铜催化的自由基加成反应,通过原位生成的亚硝基化合物直接从易得的原料制备位阻胺。该转化在室温下进行,使用丰富的铜盐,并能容忍一系列官能团。
