Several new 1,3,4-oxadiazole derivatives containing a pyrazole ring were designed and synthesized from ethyl acetoacetate and triethyl orthoformate as starting materials via multi-step reactions. The compound structures were confirmed by melting point, 1H NMR and HRMS. They were evaluated for fungicidal and herbicidal activities. Four of the compounds exhibited moderate fungicidal activity against Colletotrichum species. Most of the compounds had moderate-to-good activity as a herbicide.
