An efficient, clean and environmentally benign reaction process was developed for the convenient and cheap synthesis of hydrazone derivatives. A series of novel thiazole compounds were synthesized via one-pot three-component reaction of aldehyde/ketone, thiosemicarbazide, and chlorinated β-keto ester catalyzed by anhydrous sodium acetate. The reactions had excellent yields in EtOH solvent. The synthetic
为了方便和廉价地合成衍生物,开发了一种有效,清洁和环境友好的反应方法。通过醛/酮,硫代氨基脲和无水乙酸钠催化的氯化β-酮酯的一锅三组分反应合成了一系列新型噻唑化合物。该反应在EtOH溶剂中具有优异的产率。讨论了合成方法和反应机理。
