In order to find the new fused heterocycle of benzothiazole lead compounds, fourteen novel N-acyl-7-methoxybenzo[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.
