synthesis of aziridines by the reaction of imines derived from p-toluenesulfonamides with in situ generated iodomethyllithium, with a simple and rapid experimental protocol, is reported for the first time. The reaction with the chiral aldimine derived from phenylalaninal allowed access to (2R,1'S)-2-(1'-aminoalkyl)aziridine with very high diastereoselectivity, in enantiopure form. A mechanism to explain
首次报道了通过对甲苯磺酸酰胺衍生的亚胺与原位生成的碘代甲基锂的有效而普遍的合成,该方法具有简单而快速的实验方案。与衍生自苯丙氨酸的手性醛亚胺的反应允许以对映体纯的形式获得具有非常高非对映选择性的(2R,1'S)-2-(1'-氨基烷基)氮丙啶。提出了解释这种新颖反应的机制。
