This work describes catalytic and asymmetric aziridinations (15 examples, 95-98% ee) of benzyl bromide and imines via the imino Corey-Chaykovsky reaction using (thiolan-2-yl)diarylmethanol benzyl ether as an organocatalyst. The catalyst and analogues thereof were prepared through an expeditious and efficient synthetic route featuring a double nucleophilic substitution and Shi epoxidation as key steps
这项工作描述了使用(thiolan-2-yl)diarylmethanol苄基醚作为有机催化剂通过亚氨基Corey-Chaykovsky反应进行的苄基溴和亚胺的催化和不对称叠氮化(15例,95-98%ee)。通过快速有效的合成途径制备催化剂及其类似物,所述合成途径以双亲核取代和Shi环氧化为关键步骤。
