  Novel Synthesis of 3,4-Diaminobutanenitriles and 4-Amino-2-butenenitriles from 2-(Cyanomethyl)aziridines through Intermediate Aziridinium Salts:  An Experimental and Theoretical Approach

  摘要：

  1-Arylmethyl-2-(cyanomethyl)aziridines were transformed into 4-(N,N-bis(arylmethyl)amino)-3-(pyrrolidin-1-yl)butanenitriles and 4-(N,N-bis(arylmethyl)amino)-2-butenenitriles via 4-(N,N-bis(arylmethyl)amino)-3-bromobutanenitriles in high yields and purity. The key steps involve the unprecedented regiospecific ring opening of intermediate 2-(cyanomethyl)aziridinium salts by bromide and pyrrolidine in acetonitrile, exclusively at the substituted aziridine carbon atom. The results were rationalized on the basis of ab initio calculations.

  α-dichlorobenzyl)amino)butanenitriles with sodium methoxide in methanol resulted in novel methyl N-(2-chloro-1-(cyanomethyl)ethyl)benzimidates, although in low yields. The latter γ-chloro nitriles were smoothly converted into methyl N-(2-cyanocyclopropyl)benzimidates as precursors of biologically relevant β-ACC derivatives through a 1,3-cyclization protocol by reaction with potassium tert-butoxide in THF

  Ring opening of 1-arylmethyl-2-(cyanomethyl)aziridines with HBr afforded 3-(arylmethyl)amino-4-bromobutyronitriles via regiospecific ring opening at the unsubstituted aziridine carbon. Previous experimental and theoretical reports show treatment of the same compounds with benzyl bromide to furnish 4-amino-3-bromobutanenitriles through ring opening at the substituted aziridine carbon. To gain insights

  1-芳基甲基-2-（氰基甲基）氮丙啶与HBr的开环通过在未取代的氮丙啶碳上的区域特异性开环而提供3-（芳基甲基）氨基-4-溴丁腈。以前的实验和理论报告表明，用苄基溴处理相同的化合物，可通过在取代的氮丙啶碳上开环提供4-氨基-3-溴丁腈。为了深入了解HBr的区域选择性偏好，已使用计算方法分析了反应路径。通过使用显式溶剂分子考虑了溶剂化的影响。几何形状是在B3LYP / 6-31 ++ G（d，p）的理论水平上确定的，其中包括Grimme型校正项，用于长距离色散相互作用。亚杂化MPW1B95的功能改善了相对能量。活化屏障证实了对于HBr而言，在未取代的环碳上优选开环。通过比较相应的叠氮鎓中间体的电子结构，分析了HBr与苄基溴的开环。尽管静电图像无法解释反应的相反区域特异性，但LUMO和亲核Fukui函数的前沿分子轨道分析显示出对苄基溴情况下的取代氮丙啶碳和HBr中未取代的氮丙啶碳明显的攻击偏好

• Novel synthesis of 2-aminopentanedinitriles from 2-(bromomethyl)aziridines and their transformation into 2-imino-5-methoxypyrrolidines and 5-methoxypyrrolidin-2-ones

  1-Arylmethyl-2-(bromomethyl)aziridines were transformed into 2-[N-(arylmethyl)amino]pentanedinitriles upon treatment with an excess of potassium cyanide in DMSO through an unprecedented and peculiar reaction mechanism, involving base-induced ring opening of intermediate 2-(cyanomethyl)aziridines into allylamines, followed by migration of the double bond out of the conjugation towards aldimines via enamine intermediates. The resulting aminopentanedinitriles, served as substrates for the synthesis of novel 2-imino-5-methoxypyrrolidines upon treatment with sodium methoxide in methanol, which were either acetylated at the free imino group to afford the more stable N-acetylimino derivatives or hydrolyzed towards the corresponding synthetically relevant 5-methoxypyrrolidin-2-ones.
