The kinetic resolution of 2‐aryl‐N‐tosylaziridines and the asymmetric desymmetrization of meso‐N‐tosylaziridines by ring openings with various primary and secondary anilines, and aliphatic amines as nucleophile have been realized by using a single silver(I)/chiral diphosphine complex as catalyst for the first time. The simple starting materials, broad scope, and easy scalability render this protocol
通过使用单一的银(I)/手性二膦化合物已经实现了2-芳基-N-甲苯磺酰基氮丙啶的动力学拆分和通过各种伯胺和仲苯胺的开环而使内消旋-N-甲苯磺酰基氮丙啶的不对称脱对称以及脂族胺作为亲核试剂的方法首次将络合物用作催化剂。简单的起始原料,广泛的范围和容易的可扩展性使该方案成为制备手性邻二胺衍生物的实用方法。
