Herein, we report the H2O2-mediated synthesis of 1,2,4-thiadiazole derivatives under metal-free conditions at room temperature with ethanol as the sole solvent. Various substrates could undergo the reaction smoothly, providing the expected yields of the desired products. Moreover, the target products were obtained by filtration or extraction instead of column chromatography, which requires a large
在此,我们报告了 H 2 O 2介导的 1,2,4-噻二唑衍生物在室温下无金属条件下以乙醇为唯一溶剂的合成。各种底物可以顺利进行反应,提供预期产物的预期产率。此外,目标产物是通过过滤或萃取代替柱层析获得的,在纯化过程中需要大量的有机溶液和硅胶。所开发的合成方法可用于大规模制备 1,2,4-噻二唑衍生物作为农用化学品、药物和功能材料。
