几种杂环烯酮缩胺类化合物的合成方法研究

摘要

以α-羰基二硫缩烯酮和乙二胺为原料，乙醇为溶剂，经过连续两步反应，合成了4种杂环烯酮缩胺类化合物，讨论了合成反应机理，并用核磁、红外等测试手段对化合物进行了表征。该方法具有反应条件温和、操作简单及产率高等优点，为杂环烯酮缩胺类化合物的合成提供了新的方法。%Whileα-ketene dithioacetals and ethylene diamine were selected as raw material,ethanol as solvent, after two steps of reactions,four kinds of heterocycle ketene aminals were synthesized,the reaction mechanism was discussed.The structure of the compounds were confirmed by NMR and IR.Compared with the conventional methods,advantages of the synthetic method were detected,such as the simple raw materials,the mild reaction conditions,and the high yield of production etc.
