Abstract:

A series of strobilurin-1,2,4-triazole derivatives containing a furan or thiophen ring was designed and synthesized. The structures of the compounds were characterized by 1H NMR, 13C NMR and HRMS spectra. The bi-oassays indicated that the fungicidal activities of compounds 10b(EC50=14.82 mg/L) and 10c(EC50=18.72 mg/L) against Cercospora arachidicola Hori in vitro were much higher than that of Azoxystrobin as control(EC50=40.54 mg/L) and the fungicidal activities of compounds 10u(EC50=8.66 mg/L) and 10n(EC50=9.89 mg/L) against Rhizotonia cerealis in vitro were higher than that of the same control(EC50=10.86 mg/L). Compounds 10b, 10c, 10n and 10k could be considered as the leading compounds for further investigation.
