was synthesized via the condensation of thiosemicarbazone derivatives (III) with chloroacetyl chloride which gave a 1,3-disubstituted thiourea derivative (IV) as an intermediate compound, this was followed by cyclization of (IV) in situ boiling ethanol solvent in the presence of anhydrous potassium carbonate. The treatment of thiazole derivative (V) with 4-hydroxybenzaldehyde yielded the corresponding
摘要 2-[2-(1-(4-氯苯基)亚乙基]肼基-1,3-噻唑烷-4-酮( V )化合物通过缩氨基硫脲衍生物( III )与氯乙酰氯缩合合成,得到1,以3-二取代硫脲衍生物( IV )为中间体,在无水碳酸钾存在下,将( IV )在沸腾的乙醇溶剂中原位环化,用4-羟基苯甲醛处理噻唑衍生物( V ),得到相应的产物2,5-二取代-1,3-噻唑烷-4-酮( VI ).化合物( VI)与4-氯苯甲酰溴反应,得到5-(4-羟基亚苄基)-2-(1,2-二取代)肼基-1,3-噻唑烷-4-酮(VIII )。化合物( VI )和( VIII )用乙酸酐乙酰化形成乙酰基衍生物( VII )和( IX )。基于光谱方法和微量分析方法(元素分析)对合成化合物的结构进行了表征和确认。结果发现,大多数1,3-噻唑衍生物( V–IX )表现出酶活性,而化合物( VIII )对α-淀粉酶表现出优异的活性,IC 50值(4
