摘　　要：以离子液体[Bmim]BF_4为溶剂,实现了N-碘代丁二酰亚胺促进的咪唑并[1,2-a]吡啶衍生物与二芳基二硫醚发生的氧化芳烃硫基化反应,以中等至优良产率(73%~86%)合成系列烃硫基取代的含氮环化合物.其结构均经IR,~1H NMR,^(13)C NMR及HRMS确证.该反应具有反应条件温和、底物适用范围广、环境友好等优点,可为含有烃硫基取代的天然产物及复杂药物分子的合成提供潜在的合成途径.An efficient and practical N-iodosuccinimide-promoted regioselective arylsulfenylation of imidazo[ 1,2-a]pyridines with disulfides has been developed to afford functionalized 3-sulfenylimidazo[1,2-a]pyridines heterocycles in moderate to good yields. Their structures were confirmed by IR, 1H NMR, 13C NMR and HRMS. Furthermore, this method has the ad- vantages of mild reaction conditions, broad substrates scope and environmentally benign. Notably, the current methodology could also be conveniently applied to the synthesis of thioarylated naturally occurring biologically active frameworks.
