    Project by the “111” Project of Ministry of Education of China (No. B06005), the State Key Laboratory of Elemento-organic Chemistry and Collaborative Innovation Center of Chemical Science and Engineering (Tianjin).

A series of novel strobilurin derivatives containing 1,3,4-oxdiazole moity were designed and synthesized based on the bioisosterism and coordination of active substructure theories. The structures of new compounds were characterized by 1H NMR, 13C NMR and HRMS spectra. The bioassay indicated that the fungicidal activities of some compounds against Sclerotinia sclerotiorum reached the activity of azoxystrobin as the control and some compounds against Rhizotonia cerealis in vitro were more effective than the same control. Their structure-activity relationship was discussed. Methyl (E)-2-(2-((4-(1,3,4-oxadiazol-2-yl)phenoxy)methyl)phenyl)-3-methoxyacrylate (IIa) and methyl (E)-2-(2-((4-(5-ethyl-1,3,4-oxadiazol-2-yl)phe-noxy)methyl)phenyl)-3-methoxyacrylate (IIc) could be considered as leading compounds for further investigation.

Key words: 1,3,4-oxdiazole, strobilurin, in vitro, fungicidal activity
