antimicrobials, and corrosion inhibitors. In this study, eugenol, a natural product, was synthetically modified to generate a novel heterocyclic compound: pyrrole, which forms crystals. The latter is the outcome of the condensation reaction between eugenol hydrazide and 2,5-hexanedione, conducted under reflux ethanol conditions, without a catalyst, achieving a 96% yield. This compound structure was characterized
天然产物的半合成改性已产生许多抗癌药物、抗菌剂和缓蚀剂。在这项研究中,丁香酚是一种天然产物,被合成改性以生成一种新型杂环化合物:吡咯,它形成晶体。后者是丁香酚酰肼和 2,5-己二酮之间缩合反应的结果,在回流乙醇条件下进行,无需催化剂,产量为 96%。这种化合物结构通过 NMR 和 FTIR 等光谱方法进行了表征,并通过晶体的 X 射线衍射分析进行了验证。根据电化学研究的结果,吡咯在 1 M HCl 酸溶液中表现出对碳钢腐蚀的有效抑制作用。
