Aziridines with ease: A one‐pot synthesis of chiral aziridine derivatives with excellent diastereo‐ and enantioselectivities was developed through uninterrupted sequential reactions, including desulfonylative formation of the N‐Ts imine derived from chloroacetaldehyde, a diarylprolinol silyl ether mediated asymmetric Mannich reaction, reduction, and aziridine formation (see scheme; Ts=tosyl).
轻松实现氮丙啶:通过不间断的顺序反应,开发了具有优异非对映和对映选择性的手性氮丙啶衍生物的一锅合成方法,包括从氯乙醛衍生的N- Ts亚胺的脱磺酰化形成,二芳基脯氨醇甲硅烷基醚介导的不对称曼尼希反应,还原,和氮丙啶的形成(参见方案; Ts =甲苯磺酰基)。
