A new class of amido linked azolyl thiophenes was prepared from the synthetic intermediates azolyl amines and 5‐chlorothiophene‐2‐carbonyl chloride adopting conventional and ultrasonication methodologies. It was observed that the reaction took place in shorter reaction times with higher yields under ultrasonication. The structures of the synthesized compounds were characterized by spectral parameters
采用常规方法和超声方法,由合成中间体偶氮基胺和5-氯噻吩-2-羰基氯制备了新型的酰胺基连接的偶氮基噻吩。观察到,在超声作用下,反应以较短的反应时间发生,并且产率更高。通过光谱参数表征合成的化合物的结构,并测试其抗氧化活性。在所有测试的化合物中,甲氧基取代的恶唑基噻吩羧酰胺(8c)显示出有希望的抗氧化活性。此外,与吸电子基团相比,苯环上的给电子基团增强了抗氧化活性。
