Six novel chloro-containing 1-aryl-3-oxypyrazoles TMa–TMf with an oximino ester or an oximino amide moiety were prepared by the reaction of 1-aryl-1H-pyrazol-3-ols with benzyl bromide. Their structures were characterized by 1H-NMR, 13C-NMR, IR, MS, and elemental analysis. A preliminary in vitro bioassay indicated that compounds TMa, TMe and TMf displayed excellent fungicidal activity against Rhizoctonia solani and could be used as potential lead compounds for further development of novel fungicides.
六种新型氯含量的1-芳基-3-羟基吡唑TMa–TMf,具有氧肟酯或氧肟酰胺基团,通过1-芳基-1H-吡唑-3-醇与溴化苄的反应制备而成。它们的结构通过1H-NMR、13C-NMR、红外光谱、质谱和元素分析进行了表征。初步的体外生物测定表明,化合物TMa、TMe和TMf对根腐病菌Rhizoctonia solani表现出优异的杀菌活性,可作为进一步开发新型杀菌剂的潜在先导化合物。
