摘　　要：为了寻找新的含苯并噻唑稠杂环农药先导化合物,以2-氨基-6-甲氧基苯并噻唑为起始原料,经肼化、环化和酰基化反应,合成出了14个N-酰基-7-甲氧基苯并[4,5]噻唑并[2,3-c][1,2,4]三唑-3(2H)-硫酮,并利用1H NMR,ESI-MS及元素分析对其结构进行表征.对目标化合物进行初步的除草活性筛选,实验结果表明:在浓度为200 mg/L时,大部分化合物对黄瓜(Cucumis sativus)、小麦(Triticum aestivum)、高粱(Sorghum vulgare)、萝卜(Raphanus sativus)、油菜(Brassica campestris)和稗草(Echinochloa crusgalli)的根和茎的抑制率在85%以上.In order to find the new fused heterocycle of benzothiazole lead compounds, fourteen novel N-acyl-7-methoxy- benzo[4,5]thiazolo[2,3-c][1,2,4]triazole-3（2H）-thiones were synthesized by using 6-methoxybenzo[d]thiazol-2-amine as starting materials via hydrazine, cyclization and acylation. The structures of the target compounds were characterized by 1H NMR, ESI-MS and elemental analysis. The synthesized target compounds were screened for the herbicidal activity. The results indicated that the inhibition effects of most target compounds on the root and stem of Cucumis sativus, Triticum aestivum, Sorghum vulgare, Raphanus sativus, Brassica campestris and Echinochloa crusgalli were more than 85% at 200 mg/L.
