Research progress of oxazole derivatives in the discovery of agricultural chemicals

Abstract The search for new scaffolds is one of the important goals in the discovery of new pesticides, and the oxazoles as an important five‐membered heterocyclic compound are widely used in the discovery of new pesticides. Oxazoles ring are often used as the scaffolding structure or bridging chain to connect different reactive groups. In recent years, oxazoles have made rapid progress in the discovery of new pesticides, especially in the discovery of fungicides, insecticides, and acaricides. A systematic review of the recent research progress of oxazoles in the discovery of new pesticides is of interest. Therefore, we comprehensively reviewed the application of oxazole compounds in the discovery of new pesticides from 2003 to 2023; summarized the fungicidal, antibacterial, insecticidal, acaricidal, and herbicidal activities of oxazoles; and discussed the structure–activity relationship, physiochemical and mechanism of action, with the aim of providing inspiration and ideas for the discovery of oxazoles as novel agrochemicals.
