1-Arylmethyl-2-(bromomethyl)aziridines were transformed into novel 2-(2-cyanoethyl)aziridines upon treatment with α-lithiated trimethylsilylacetonitrile in THF in an efficient and straightforward approach. The latter aziridines underwent ring opening by reaction with benzyl bromide in acetonitrile, affording 5-amino-4-bromopentanenitriles through a regiospecific ring opening of intermediate aziridinium
用α-锂化的三甲基甲硅烷基乙腈在THF中以一种有效且直接的方法处理后,将1-芳甲基-2-(溴甲基)氮丙啶转化为新型的2-(2-氰乙基)氮丙啶。后者的氮丙啶通过与苄基溴在乙腈中的反应进行开环,通过中间体的叠氮鎓盐的区域特异性开环得到5-氨基-4-溴戊腈。这些γ-bromonitriles的进一步阐述导致新颖的合成2- [ Ñ,Ñ双(芳甲基)氨基甲基] cyclopropanecarbonitriles以高产率通过在处理1,3-环化协议与KO的手段吨卜的THF溶液。
