Forty one novel 1,3,4‐oxadiazole/thiadiazole thioether derivatives containing phenoxy moiety were designed and synthesized. Bioassay demonstrated that some of them showed remarkable activities against Tylenchulus semipenetrans in vitro and in vivo. Compounds 20, 21, 35 and 39 showed excellent lethal activities after treatment for 48 h in vitro, with LC50 values of 13.4 ± 1.8, 11.7 ± 2.5, 13.7 ± 2.4
AbstractA new series of 1,3,4-oxadiazole derivatives with a 3-chloropyridin-2-yl-1H-pyrazole moiety was designed, synthesized, and characterized. The results of bioassay against Helicoverpa armigera and Plutella xylostella indicated that some of the synthesized compounds showed remarkable larvicidalactivity. In particular, the LC50 values of the most active compounds against P. xylostella were 46
