were elucidated by 1H and 13C NMR, IR, and HRMS data. These derivatives were evaluated in vitro for their fungicidal activity against Fusarium solani sp. Among the nine triazolic thymol derivatives obtained, seven of them were found to have moderated antifungal activity. In contrast, naphthoquinone/thymol hybrid ether 2b displayed activity comparable with that of the commercial fungicide thiabendazole
通过威廉姆森合成和铜催化叠氮化物-炔环加成 (CuAAC) 方法实现了 15 种新百里酚衍生物的半合成。CuAAC 使用“点击化学”策略,在炔基百里酚衍生物和商业或制备的叠氮化物存在下的反应,在微波辐射下提供了九种百里酚衍生物。该程序减少了反应时间和成本。通过1 H 和13 C NMR、IR 和 HRMS 数据阐明了所有分子实体。体外评估了这些衍生物对茄病镰刀菌的杀真菌活性sp. 在获得的九种三唑百里酚衍生物中,发现其中七种具有适度的抗真菌活性。相比之下,萘醌/百里酚杂化醚2b显示出与商业杀菌剂噻苯达唑相当的活性。讨论了最活跃的化合物2b的构效关系,并通过可能与真菌麦角甾醇结合和干扰 K +渗透平衡进入细胞外介质来预测作用模式。
