analyses. The herbicidal activities of synthesized compounds were evaluated against Echinochloa cruss‐galli, Avena fatua, and Sorgum halepense weeds. Compounds 7 and 12a showed potential herbicidal activity against gramineous weeds. Our results may provide some guidance for synthesis development of some novel oxa or thiadiazole and triazole‐based herbicidal lead structures.
合成一些新的1,2,4-三唑,1,3,4-恶二唑和1,3,4-噻二唑并带有(R)5-(1-(4-(5-氯-3-氟吡啶3)据报道,作为商业除草剂的一部分的-(yloxy)phenoxy)ethyl)单元,分别在碱性,碘和酸性介质中使用它们的硫代氨基脲。合成的化合物的结构通过IR,1 H,13 C NMR光谱数据和元素分析来表征。对合成化合物的除草活性进行了评估,以防E草,燕麦和fat实高粱。化合物7和12a表现出对禾本科杂草的潜在除草活性。我们的结果可能为一些新型的以氧杂或噻二唑和三唑为基础的除草剂铅结构的合成开发提供一些指导。
