Synthesis and insecticidal activity of novel benzoxazole derivatives
[Aims]This study aims to discover new compounds with insecticidal activities.[Methods]According to scaffold hopping method,15 novel benzoxazole derivatives were designed and synthesized,and their insecticidal activities were tested.[Results]Results of preliminary bioassay activities in green house showed that at 600 mg/L all the target compounds exhibited good insecticidal activities against Mythimna separata and Plutella xylostella,with mortality rates of 100％,but showed no activities against Myzus persicae and Tetranychus cinnabarinus,with mortality rates of 0,all at 600 mg/L.[Conclusions]The compounds could be lead compounds for further structural optimization study.
