在水相中碱性离子液体[bmim][OH]催化作用下,由苊醌、丙二腈/氰乙酸乙酯和β-二酮三组分“一锅法”合成了一系列螺杂环化合物,产物的结构通过1H NMR,IR和MS表征.该方法条件温和,操作简单,后处理方便,反应时间短,对环境友好,且催化剂廉价易得.
Under the catalysis of basic ionic liquid [bmim] [OH] in water phase, a series of spirochetes were synthesized from the three components of 苊 quinone, malononitrile / ethyl cyanoacetate and β-diketone The structure of the product was characterized by 1H NMR, IR and MS. The method was mild, easy to operate, convenient for post-treatment, short reaction time, friendly to the environment and cheap for the catalyst.
