We describe herein the ring-opening reaction of chiral 1,1’-sulfonyl bis-aziridines with
various neutral and anionic nucleophiles including benzylamine, piperidine, acetate, allylthiolate,
cyanide anion and sodium ethoxide. These reactions afforded bis-opened or/and mono-opened
compounds via a regioselective attack on the non-substituted methylene of aziridine ring. The
structures of the products were confirmed based on spectral analysis (IR, 1H NMR and 13C NMR).
A theoretical study by density functional theory (DFT) was used to rationalize the region-selective
ring-opening of starting bis-aziridines.
我们在此描述手性1,1'-磺酰双环氮烷与各种中性和负离子亲核试剂包括
苄胺、
哌啶、
乙酸盐、
丙烯硫醇盐、
氰离子和乙氧基
钠的开环反应。这些反应通过对环氮烷的非取代亚甲基的区域选择性攻击,形成了双开放或/和单开放化合物。产品的结构基于光谱分析(IR,1H NMR和13C NMR)得到确认。通过密度泛函理论(DFT)进行的理论研究用于解释起始双环氮烷的区域选择性开环反应。
