摘要：

To find new strobilurin analogues with high activity against resistant pathogens, a series of (E)-alpha-(methoxyimino) benzeneacetate derivatives containing 1,2,4-triazole Schiff base side chain were designed and synthesized. Their structures were confirmed by IR, H-1 NMR, and C-13 NMR, ESI-HRMS, or elemental analyses. Bioassays indicated that most of the target compounds showed moderate to good fungicidal activities against Rhizoctonia solani, Botrytis cinerea Pers., Fusarium graminearum, Cotton rhizoctoniosis, and Blumeria graminis. For example, compounds 6g and 6j exhibited promising antifungal activity against Rhizoctonia solani, Botrytis cinerea Pers., and Fusarium graminearum. Compounds 6c, 6l, and 6m had higher fungicidal activities against Blumeria graminis at the concentration of 50 mu g/mL; inhibitory rate is 91.41%, 92.13%, and 91.77%, respectively.
