A series of 2-substituted benzimidazoles, benzoxazoles were synthesized by the condensation reactions of 1-aryl-4-carboxy-2-pyrrolidinones and aromatic ortho-diamines or ortho-aminophenol. Alkylation of benzimidazoles with iodoalkanes led to 1-aryl-4-(1-alkyl-1H-benzimidazol-2-yl)-2-pyrrolidin- ones or 1,3-dialkylbenzimidazolium iodides. N-Subs- tituted γ-amino acids were prepared by the hydrolysis
通过1-芳基-4-羧基-2-吡咯烷酮与芳香族邻二胺或邻氨基苯酚的缩合反应合成了一系列2-取代苯并咪唑、苯并恶唑。苯并咪唑与碘代烷烃的烷基化产生 1-芳基-4-(1-烷基-1H-苯并咪唑-2-基)-2-吡咯烷酮或 1,3-二烷基苯并咪唑鎓碘化物。N-取代的γ-氨基酸是通过1-芳基-4-(1H-苯并咪唑-2-基)-2-吡咯烷酮在氢氧化钠溶液中水解制备的,然后用乙酸处理。使用 IR 和 1H、13C NMR 光谱、MM2 分子力学和 AM1 半经验量子力学方法研究了合成产物的结构。© 2006 Wiley Periodicals, Inc. 杂原子化学 17:47–56, 2006; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20171
