A series of novel (Z)-1-tert-butyl (or phenyl)-2-(1H-1,2,4-triazol-1-yl)- ethanone O-[2,4-dimethylthiazole (or 4-methyl-1,2,3-thiadiazole) -5-carbonyl] oximes 5a-5c and (1Z, 3Z)-4,4-dimethyl-1-substitutedphenyl-2-(1H-1,2,4-triazol- 1-yl)-pent-1-en-3-one O-[2,4-dimethylthiazole (or 4-methyl-1,2,3-thiadiazole)-5- carbonyl] oximes 6a-6e were synthesized by the condensations of (Z)-1-tert-butyl (or phenyl)-2-(1H-1,2,4-triazol-1-yl)-ethanone oximes 3 or (1Z, 3Z)-4,4-dimethyl-1-substitutedphenyl-2-(1H-1,2,4-triazol-1-yl)-pent-1-en-3-one oximes 4 with 2,4-dimethylthiazole-5-carbonyl chloride or 4-methyl-1,2,3- thiadiazole-5-carbonyl chloride in the basic condition. Their structures were confirmed by IR, 1H NMR, mass spectroscopy, and elemental analyses. The results of preliminary bioassays showed the title compounds 5 and 6 exhibited moderate to good fungicidal activities. For example, compound 6c possessed 86.4% inhibition against Fusarium oxysporum, and compound 6b exhibited 86.4 and 100% inhibition against Fusarium oxysporum and Cercospora arachidicola Hori at the concentration of 50 mg/L, respectively.
