Based on avermectin structure framework,a series of novel 4 -avermectin triazole derivatives containing amide unit were synthesized via the method of click reaction and amidation.The structures of target compounds were fully characterized by 1 H NMR,13 C NMR and HRMS.The preliminary bioassay showed that the target compounds possessed certain insceticidal activities against Tetranychus cinnabarinus,Myzus persicae and Caenorhabditis elegans.At the concentration of 0.1 μg/m L,the lethal rates of 4-(1-(4-(2-(4-...
