A series of 5-pyrimidinyl-1,2,4-oxadiazole derivatives were synthesized by the reaction of substituted benzamidoxime with pyrimidinecarbonyl chloride, and their structures were characterized. As a representative, the structure of compound 5a was confirmed with X-ray crystallography. Molecular docking was used to investigate the binding conformations of several compounds to the active site of yeast ACCase and predict the bioactivity, and the results revealed that the binding modes are similar to that as diclofop in complex with ACCase. Preliminary bioassay showed that most of title compounds have good herbicidal activity.
