Niphathesine C and related pyridine alkaloids are well known natural products with interesting antimicrobial activities, characterized by a pyridine ring and a lipophilic side chain with a terminal nitrogen‐containing functional group. This paper describes the synthesis of analogues of these alkylpyridine alkaloids with variation of the heterocyclic ring and the terminal functional group. Key steps
Niphathesine C 和相关的吡啶生物碱是众所周知的具有有趣抗菌活性的天然产物,其特征在于一个吡啶环和一个带有末端含氮官能团的亲脂侧链。本文描述了这些烷基吡啶生物碱的杂环和末端官能团变化的类似物的合成。合成的关键步骤是适当的芳基碘化物与 undec-10-ynol 或 undec-10-ynoic 酸衍生物的 Sonogashira 反应。所得化合物在琼脂扩散试验中针对几种细菌和真菌进行了测试。
