A series of novel 1,5-diaryl-1H-pyrazol-3-oxy derivatives containing oxyacetic acid or oxy(2-thioxothiazolidin-3-yl)ethanone moieties were prepared from methyl 3-arylacrylates via a serial of reactions included addition-cyclization, oxidation, substitution, hydrolysis, and condensation. Their structures were confirmed by 1H-NMR, 13C-NMR, IR, and elemental analysis. In addition, the crystal structure of the compound 2-(1,5-diphenyl-1H-pyrazol-3-yloxy)-1-(2-thioxothiazolidin-3-yl)ethanone was determined by single crystal X-ray diffraction analysis. Bioassay results indicated that the compound 2-(5-(4-chlorophenyl)-1-phenyl-1H-pyrazol-3-yloxy)- 1-(2-thioxo-thiazolidin-3-yl)ethanone exhibited moderate inhibitory activity against Gibberella zeae at the dosage of 10 μg mL-1.
