Abstract: In order to develop new herbicidal active compounds and research the structure-activity relationship, twenty-two new sulfonylurea derivatives with trisubstituting group in the pyrimidine ring were designed and synthesized. Their structures were confirmed by 1H NMR, MS and elemental analysis. Preliminary herbicidal activity of these new sulfonylurea compounds was determined by pot bioassay experiments at dosage of 1.5 kg/ha. The results show that these trisubstituted pyrimidine phenylsulfonylurea derivatives display weak heribicidal activity and the addition of 5-substituting group of the pyrimidine ring affected the herbicidal activity slightly.

Key words: Sulfonylurea, Pyrimidine, Herbicidal activity
