Coumarinyl 1,3,4-oxadiazoles were synthesized from Schiff bases and acetic anhydride. All compounds were characterized by melting points and their structures confirmed by mass and $^1}$H and $^13}$C NMR spectrometry. These novel coumarinyl derivatives were subjected to antibacterial, antifungal, anta atoxigenic, and antioxidant activity. Their activity varied depending on their structure, where 2-(3-acetyl-5-(((4-methyl-2-oxo-2H-chromen-7-yl)oxy)methyl)- 2,3-dihydro-1,3,4-oxadiazol-2-yl)-1,4-phenylene diacetate showed significant antioxidant and antibacterial activity on B. subtilis. 4-(3-Acetyl-5-(((4-methyl-2-oxo-2H-chromen-7-yl)oxy)methyl)-2,3-dihydro-1,3,4-oxadiazol-2-yl)-1,2-phenylene diacetate was found to possess excellent antifungal and antia atoxigenic activity.
苯并香豆素基1,3,4-恶二唑化合物通过Schiff碱与乙酸酐反应合成。 所有化合物都通过熔点和质谱以及 1H 和 13C NMR 波谱表征。 将这些新型的苯并香豆素衍生物进行抗菌、抗真菌、抗毒素和抗氧化活性测试。 其活性因结构而异,2-(3-乙酰基-5-(((4-甲基-2-氧代-2H-色烯-7-基)氧基)甲基)-2,3-二氢-1,3,4-恶二唑-2-基)-1,4-苯二乙酸酯在枯草芽孢杆菌 (B. subtilis) 上的显示出显著的抗氧化和抗菌活性。 4-(3-乙酰基-5-(((4-甲基-2-氧代-2H-色烯-7-基)氧基)甲基)-2,3-二氢-1,3,4-恶二唑-2-基)-1,2-苯二乙酸酯被发现具有优异的抗真菌和抗毒素活性。
