reaction of 2a with hydroxylamine hydrochloride, while its reactions with hydrazines afforded the respective 4,5-dihydro-1H-pyrazoles. The target compounds were evaluated as antioxidant and antibacterial agents. The tested compounds showed good to moderate activities compared to ascorbic acid and chloramphenicol, respectively.
姜黄素与对甲苯胺、2-氨基吡啶和4-氨基安替比林的不同重氮盐在吡啶中发生重氮偶联反应,得到芳基腙2a-c。对甲苯胺的芳基腙与尿素、硫脲、硝酸胍反应生成5,6-二氢嘧啶。2a与2,3-二氨基吡啶在乙醇钠溶液中进一步反应,得到1H-吡啶并[2,3-b][1,4]二氮杂卓衍生物。双(2,5-二氢异恶唑)由2a与盐酸羟胺反应得到,而其与肼反应分别得到4,5-二氢-1H-吡唑。目标化合物作为抗氧化剂和抗菌剂进行了评估。与抗坏血酸和氯霉素相比,测试的化合物分别显示出良好至中等的活性。
