Semisynthetic phenol derivatives were obtained from the natural phenols: thymol, carvacrol, eugenol, and guaiacol through catalytic oxychlorination, Williamson synthesis, and aromatic Claisen rearrangement. The compounds characterization was carried out by 1H NMR, 13C NMR, and mass spectrometry. The natural phenols and their semisynthetic derivatives were tested for their antimicrobial activity against
通过催化氧氯化,威廉姆森合成和芳族克莱森重排,从天然酚类百里酚,香芹酚,丁子香酚和愈创木酚中获得半合成酚衍生物。化合物的表征通过1 H NMR,13 C NMR和质谱进行。测试了天然酚及其半合成衍生物对细菌的抗微生物活性:金黄色葡萄球菌,大肠杆菌,无毒李斯特菌,铜绿假单胞菌,肠炎沙门氏菌,鼠伤寒沙门氏菌。肠杆菌和蜡状芽孢杆菌。使用220至3.44μgmL –1的浓度确定最小抑菌浓度(MIC)和最小杀菌浓度(MBC)值。对于所有用于分析的细菌,大多数测试化合物的MIC值均≤220μgmL –1。化合物的分子性质用PM6方法计算。通过主成分分析,将具有较高抗菌潜能的天然酚及其半合成衍生物归为一组。
