摘要
Based on benalaxyl pesticide metabolite structure framework, fourteen novel diamide derivatives were synthesized by the reaction of amine and N-2-carboxyacetyl-N'-(2,6-dimethylphenyl)alanine methyl ester. Their structures were identified by H-1 NMR, C-13 NMR spectra and HRMS. The results of bioassay indicated that some compounds possess potential fungicidal activities against 8 kinds of bacteria, and the antibacterial activity of some compounds was better than that of benalaxyl. At a dosage of 5.0 X 10(-5) g/mL,, compound 7d displayed 94.2% antifungal activities against Rhizoctonia solani. Compound 8f displayed 87.1% and 88.9% antifungal activities against Phytophthora capsici and Rhizoctonia solani.
