A novel and efficient one-pot method has been developed for the synthesis of 2-substituted-5H-1,3,4-thiadiazolo[3,2-a]pyrimidin-5-one derivative by the combination of [3 + 3] cycloaddition, reduction, deamination reactions. The fused heterocyclic compounds 2-substituted-5H-1,3,4-thiadiazolo[3,2-a]pyrimidin-5-ones was synthesized by the diversity-oriented catalysis. As an extension of the synthetic
通过[3 + 3]的组合,开发了一种新颖且有效的一锅法,用于合成2-取代的-5 H -1,3,4-噻二唑并[3,2- a ]嘧啶-5-酮衍生物。环加成,还原,脱氨基反应。通过多样性取向催化合成了稠合的杂环化合物2-取代的-5 H -1,3,4-噻二唑并[3,2 - a ]嘧啶-5-酮。作为合成方法的扩展,合成了一些4 H-吡啶并[1,2- a ]嘧啶-4-酮4a–c。在晶体中讨论了超分子自组装的π-π堆积结构。
