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‐dipheny
由3-芳基丙烯酸甲酯通过一系列反应制备了一系列新颖的1,5-二芳基-1 H-吡唑-3-氧基衍生物,其中含有氧乙酸或氧(2-硫代噻唑并恶唑啉-3-基)乙酮部分。环化,氧化,取代,水解和缩合。其结构通过1 H-NMR,13 C-NMR,IR和元素分析确认。此外,通过单晶X射线衍射分析确定了化合物2-(1,5-二苯基-1H-吡唑-3-基氧基)-1-(2-硫代噻唑啉酮-3-基)乙酮的晶体结构。生物测定结果表明化合物2-(5-(4-氯苯基)-1-苯基-1 H吡唑-3-基氧基)-1-(2-硫代-噻唑烷-3-基)乙酮在10μgmL -1的剂量下对玉米赤霉病菌表现出中等的抑制活性。
