6-sulfonate pyrimidyl salicylate compound and preparation method and application thereof

The invention relates to the field of herbicides and discloses a 6-sulfonate pyrimidyl salicylate compound and a preparation method and application thereof. The compound has a structure as shown in a formula (1). The method for preparing the 6-sulfonate pyrimidyl salicylate compound comprises the steps of (1) carrying out first contact reaction on the compound as shown in a formula (2) and R2SO2Cl to obtain a compound as shown in a formula (3); and (2) carrying out second contact reaction on the compound as shown in the formula (3) and trifluoroacetic acid. The 6-sulfonate pyrimidyl salicylate compound has a good inhibition effect on acetohydroxyacid synthase, and has significant resistance inhibition effect on weeds which are resistant to an acetohydroxyacid synthase inhibitor herbicide, thereby controlling weed resistance plants caused by acetohydroxyacid synthase. The formulas are as shown in the specification.
