A method for the catalytic, enantioselective, intermolecular, 1,2-sulfenoamination of alkenes is described. Functionalization is achieved through the intermediacy of an enantioenriched, configurationally stable thiiranium ion generated by Lewis base activation of a readily available sulfur electrophile. A diverse set of anilines and benzylamines react with different styrenes to afford products in good
描述了一种催化、对映选择性、分子间、1,2-亚磺胺化烯烃的方法。功能化是通过路易斯碱活化容易获得的硫亲电子试剂产生的对映体富集的、构型稳定的硫鎓离子的中介实现的。一组不同的苯胺和苄胺与不同的苯乙烯反应,以良好的收率和立体选择性提供产品。通过胺的去质子化以实现碳-硫键断裂,促进了产物的下游操作。
