A method is proposed for the synthesis of ethyl 5-(3-aryl-4-formyl-1H-pyrazol-1-yl)-1,2,3-thiadiazole-4-carboxylates by a reaction of acetophenone (4-ethoxycarbonyl-1,2,3-thiadiazol-5-yl)hydrazones with a Vilsmeier–Haack complex. The obtained heterocyclic assemblies provide interesting substrates for further modification and study of biological activity.
提出了一种通过苯乙酮(4-乙氧基羰基)反应合成5-(3-芳基-4-甲酰基-1 H-吡唑-1-基)-1,2,3-噻二唑-4-羧酸乙酯的方法-1,2,3-噻二唑-5-基)hydr与Vilsmeier-Haack配合物。所获得的杂环组装体为进一步修饰和研究生物活性提供了有趣的底物。
