Substituted azepanes are common bioactive epitopes with flexible ring structures. The conformational effects of monofluorination in model azepane rings were investigated by (1)H NMR spectroscopy and computational modelling. A single fluorine atom, installed diastereoselectively, was found to bias the azepane ring to one major conformation for one diastereomer.
取代氮杂环庚烷是具有柔性环结构的常见生物活性表位。通过 (1)H NMR 光谱和计算建模研究了模型氮杂环庚烷环中单氟取代的构象效应。发现一个氟原子被非对映选择性地安装，使氮杂环庚烷环偏向一个主要构象，对于一个非对映异构体。
