A new entry to optically pure trans-2,3-disubstituted N-sulfinyl aziridines starting from 1,2-aminosulfides, involving formation of a sulfonium salt intermediate followed by intramolecular nucleophilic attack by the sulfinamide nitrogen atom, is reported. The regio- and stereoselective opening of the aziridine ring can be achieved by anchimeric assistance of the sulfinyl group.
据报道,从1,2-氨基硫化物开始的光学纯的反式-2,3-二取代的N-亚磺酰基氮丙啶的新进入,涉及形成salt盐中间体,然后由亚磺酰胺氮原子进行分子内亲核攻击。氮丙啶环的区域和立体选择性开放可通过亚磺酰基的嵌合辅助来实现。
