Résumé The synthesis of novel imidazolium ionic liquid, tagged Schiff, has been described. The synthesis was achieved in three steps from 2,4-dihydroxybenzaldehyde by selective alkylation with 1,3-dibromopropane, followed by reaction with 1-methylimidazole and Schiff base formation with aromatic amines. The compounds were evaluated for antibacterial and antifungal activities. The ionic liquid tagged Schiff base 4a showed the inhibition of both Gram positive and Gram negative bacteria. It also showed broad spectrum antifungal activity against all four tested fungi; however, 4f showed highest antifungal activity against A. niger.

摘要 描述了新型咪唑离子液体(标记为 Schiff)的合成。合成过程分为三个步骤,首先用 1,3-二溴丙烷对 2,4-二羟基苯甲醛进行选择性烷基化,然后与 1-甲基咪唑反应,再与芳香胺形成希夫碱。对这些化合物进行了抗菌和抗真菌活性评估。离子液体标记的希夫碱 4a 对革兰氏阳性菌和革兰氏阴性菌都有抑制作用。它还对所有四种受试真菌表现出广谱抗真菌活性;不过,4f 对黑曲霉的抗真菌活性最高。 补充材料: 本文的补充材料以单独文件形式提供:mmc1.doc
