Synthesis and Antibacterial Activities of 2-Aryl-3-N-Propanoyl-5-(4-Pyridyl)-1,3,4-Oxadiazoline Derivatives
【摘要】 4-吡啶苯甲酰肼(1)与芳香醛缩合得到酰腙(2a~2h),而后2a~2h与丙酸酐环合,以良好的收率合成出2-芳基-3-N-丙酰基-5-(4-吡啶基)-1,3,4-口恶唑啉类衍生物(3a~3h),并通过元素分析,IR,1H NMR和MS对3a~3h的结构进行了表征.初步的抗菌试验表明,部分目标化合物表现出较好的抑菌活性.
【Abstract】 Condensation of 4-picolinyl hydrazine(1) with aromatic aldehydes produced corresponding hydrazones(2a~2h).Cyclization of 2a~2h with propanoic anhydride gave the title compounds 3a~3h in good yield.The structures of 3a~3h were characterized by elementary analyses,IR,1H NMR,and MS spectroscopy.The preliminary antibacterial tests showed that most of them had good antibacterial activities.
