In this work, we report the synthesis of 2H-1,3,5-oxadiazine-2,4(3H)-diimine derivatives based on acylated thioureas. The method for the preparation of 1,3,5-oxadiazine derivatives is based on the reaction of dehydrosulfurization of the starting acylated thioureas under the action of dicyclohexylcarbodiimide (DCC) followed by the [4 + 2] cycloaddition reaction of another DCC molecule to the resulting
在这项工作中,我们报道了基于酰化硫脲的2 H -1,3,5-恶二嗪-2,4(3 H )-二亚胺衍生物的合成。1,3,5-恶二嗪衍生物的制备方法是以酰化硫脲为起始原料,在二环己基碳二亚胺(DCC)作用下进行脱氢硫化反应,再与另一个DCC分子进行[4+2]环加成反应。所得中间体碳二亚胺。所得1,3,5-恶二嗪衍生物的结构通过1 H, 13 C NMR、IR光谱、质谱和X射线衍射分析证实。
