以一元取代苯甲酸为原料合成了17个取代苯甲酸酯类化合物,其中有8个是新化合物,其结构均通过核磁共振氢谱和电喷雾电离质谱确证。精密毒力测定结果表明,3j对黄瓜褐斑病菌Corynespora cassiicola、3l对水稻恶苗病菌Fusarium moniliforme的EC50值分别为22.80和12.34 mg/L。
Seventeen substituted benzoic acid esters were synthesized from monobasic substituted benzoic acids. Eight of them were new compounds and their structures were confirmed by 1H-NMR and ESI-MS, respectively. The results of the precision virulence test showed that the EC50 values of 3j to Corynespora cassiicola and 3l against Fusarium moniliforme were 22.80 and 12.34 mg / L, respectively.
