report the synthesis of a series of new 4H-1,3,5-oxadiazine derivatives. The method of their production is based on the dehydrosulfurization reaction of N-(2,2,2-trichloro-1-(3-R-thioureido)ethyl)carboxamides under the action of a mixture of iodine and triethylamine in DMF. A possible reaction mechanism has been proposed. The target products have been obtained in 58%–75% yield. The structure of the obtained
在这项工作中,我们报道了一系列新的 4 H-1,3,5-噁二嗪衍生物的合成。其生产方法基于 N-(2,2,2-三氯-1-(3-R-硫脲基)乙基)甲酰胺在 DMF 中碘和三乙胺混合物作用下的脱氢硫化反应。已经提出了一种可能的反应机制。以 58%–75% 的收率获得目标产品。所得化合物的结构已通过 1H、13C NMR、IR 光谱数据和对 6-(叔丁基)-N-苯基-4-(三氯甲基)-4 H-1,3,5-噁二嗪-2-胺进行的 X 射线衍射分析得到证实。
