Abstract

The known sesquiterpenes that arise biosynthetically from hedycaryol are summarised. Reasonings for the assignments of their absolute configurations are discussed. The analysis provided here suggests that reprotonations at the C1=C10 double bond of hedycaryol are directed toward C1 and generally lead to 6-6 bicyclic compounds, while reprotonations at the C4=C5 double bond occur at C4 and result in 5-7 bicyclic compounds.

摘要

从贺迪卡醇生物合成的已知倍半萜类化合物被总结。对其绝对构型的分配理由进行了讨论。这里的分析表明,贺迪卡醇 C1=C10 双键的质子化反应是定向于 C1 的,通常导致 6-6 双环化合物,而 C4=C5 双键的质子化反应发生在 C4 上,导致 5-7 双环化合物。详细内容见 H. Xu 和 J. S. Dickschat 的综述(DOI:10.1002/chem.202200405)。
