Abstract Employing the intermediate derivatization method (IDM), twenty novel 1,3,4-oxadiazole derivatives containing arylpyrazoloxyl moiety were designed and synthesized. The structures of the title compounds were identified by 1H NMR, 13C NMR, MS and elemental analyses, compound 4 was further identified by single-crystal X-ray diffraction. Antifungal activities against rice sheath blight (RSB) and
摘要采用中间衍生法(IDM),设计合成了二十种新颖的含芳基吡唑基的1,3,4-恶二唑衍生物。通过1 H NMR,13 C NMR,MS和元素分析鉴定标题化合物的结构,通过单晶X射线衍射进一步鉴定化合物4。通过菌丝体线性生长速率法评估了对水稻鞘枯病(RSB)和高粱炭疽病(SA)的抗真菌活性。化合物4、16和20表现出显着的抗RSB活性(分别为EC50 = 0.88 mg / L,0.91 mg / L和0.85 mg / L),高于参考戊丁康唑。化合物3表现出更高的抗SA活性(EC50 = 1.03 mg / L),与市售吡菌胺酯(EC50 = 1.06 mg / L)相同。
