Abstract A new, simple method for the synthesis of 4H-1,3,5-oxadiazine derivatives was developed based on the dehydrogenation reaction of N-amidoalkylated thioureas with dicyclohexylcarbodiimide. The reaction was carried out in acetonitrile under reflux for 50–60 min. The precipitated products were easily purified by crystallization from acetonitrile or ethanol. The yields were 30–70%. The structure
摘要 基于N-酰氨基烷基化硫脲与二环己基碳二亚胺的脱氢反应,开发了一种新的、简单的合成4H-1,3,5-恶二嗪衍生物的方法。反应在乙腈中回流50-60分钟。沉淀的产物很容易通过从乙腈或乙醇中结晶来纯化。产率为 30-70%。合成化合物的结构通过IR、1H NMR、13C NMR、MS和X射线晶体学确定。
