A facile and rapid method for the synthesis of novel imidazole and benzimidazole aromatic acyclic nucleosides is described. Synchronous N-alkylation of imidazole or benzimidazole and potassium aryloxide with methylene iodide in the presence of triethylamine and a catalytic amount of tetrabutylammonium bromide (TBAB) in dry acetonitrile or acetone gave moderate yields of the acycloaromatic nucleoside
描述了一种方便快捷的合成新型咪唑和苯并咪唑芳族无环核苷的方法。在三乙胺和催化量的四丁基溴化铵(TBAB)在干燥的乙腈或丙酮中存在下,将咪唑或苯并咪唑和芳基氧化钾与亚甲基碘进行同步N烷基化反应可得到中等收率的无环芳族核苷类似物。
