In order to find pesticidal lead compounds with high activity, a series of novel diamide compounds were designed and synthesized by using metalaxyl as a leading compound, as well as the principle of active substructure combination. The structures of the target compounds were confirmed by 1H NMR, 13C NMR and HRMS. The preliminary bioassay showed that compound 5j showed an 85% inhibition rate against Pseudoperoniospora cubensis at 50 mg/L, most of the target compounds had good insecticidal activity against Oriental armyworm at 500 mg/L, and compounds 5b, 5f, 5g, 5h, 5i and 5l have a mortality rate of 100% against Oriental armyworm. At 250 mg/L, the mortality rate of compounds 5f, 5h and 5l against Oriental armyworm was 50%.

Key words: diamide compound, synthesize, biological activity
