substituted pyrazole derivatives were prepared from N1-[4-(cinnamoyl) phenyl]-5-chloro-2-methoxybenzamides 2a–c, which were prepared from N-(4-acetylphenyl)-5-chloro-2-methoxybenzamide as starting material. Treating of compound 2a–c with methylhydrazine or phenylhydrazine afforded the corresponding N-substituted pyrazoline derivatives 3a–c and 4a–c, respectively. The acryloyl derivatives 2a–c were reacted
由N 1- [4-(肉桂酰基)苯基] -5-氯-2-甲氧基苯甲酰胺2a – c制备了一系列取代的吡唑衍生物,它们由N-(4-乙酰基苯基)-5-氯-2-制备甲氧基苯甲酰胺为起始原料。用甲基肼或苯肼处理化合物2a – c分别得到相应的N-取代吡唑啉衍生物3a – c和4a – c。丙烯酰基衍生物2a – c与水合肼在二恶烷中反应,得到吡唑啉5a –c,将其在二恶烷中用乙酰氯乙酰化,得到N-乙酰基类似物6a - c。另外,吡唑啉5c在低聚甲醛的存在下与吗啉反应,得到相应的N-取代的吡唑啉衍生物7。新化合物的结构分配基于化学和光谱学证据。药理学筛选显示,这些化合物中的许多化合物毒性较小,抗炎活性良好。
