[reaction: see text] An efficient and straightforward method for the preparation of highly enantiomerically enriched C2-symmetrical vicinal diamines by the reductive homocoupling of aromatic N-tert-butanesulfinyl imines in the presence of SmI2 and HMPA was developed. It gives access to a variety of enantiopure C2-symmetrical 1,2-diamines in a very mild and practical way.
[反应：见正文] 开发了一种高效且直接的方法，用于在SmI2和HMPA存在下通过芳族N-叔丁基亚磺酰亚胺的还原均偶联制备高度对映体富集的C2对称邻二胺。它以非常温和且实用的方式获得了多种对映纯的C2对称1,2-二胺。
