A series of new N-acylhydrazone derivatives were synthesized in good yields through the reactions of dehydroabietic acid hydrazide with a variety of substituted arylaldehydes. The structures of the synthesized compounds were confirmed by IR, 1H- and 13C-NMR, ESI-MS, elemental analysis and single crystal X-ray diffraction. From the crystal structure of compound 4l, the C=N double bonds of these N-acylhydrazones
通过脱氢枞酸酰肼与多种取代芳醛的反应,以良好的收率合成了一系列新的N-酰基腙衍生物。合成化合物的结构经IR、1H-和13C-NMR、ESI-MS、元素分析和单晶X射线衍射确证。从化合物4l的晶体结构来看,这些N-酰基腙的C=N双键显示为(E)-构型,而化合物4a-q的NMR数据表明溶液中每种化合物存在两个旋转异构体。评估了目标化合物对四种微生物菌株的抗菌活性。结果表明,几种化合物表现出明显的抗菌活性。特别,化合物4p对金黄色葡萄球菌和枯草芽孢杆菌表现出良好的抗菌活性,与阳性对照相当。还讨论了可能的抗菌代谢和进一步优化该化合物的策略。
