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 nitrosocompounds 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.
空间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 Cu 催化的自由基加成与原位生成的亚硝基化合物,以直接从容易获得的材料制备位阻胺。转化在室温下进行,使用丰富的铜盐,并且可以耐受一系列官能团。
