Using 5-methyl-1,3,4-oxadiazol-2(3H)-one as starting material, twelve novel 1,2,4-triazinone derivatives were synthesized through alkylation, ring-enlargement, hydrolysis and amidation. All title compounds were characterized by 1H NMR, 13C NMR and MS. The preliminary bioassay indicated that some of the compounds exhibited certain fungicidal activities against Gibberella zeae, Fusarium oxysporum and Cytospora mandshurica at a dosage of 50μg/mL.
