A biomimetic synthesis of a model compound for the marine alkaloid halicyclamine A is reported that involves a macrocyclization through the intramolecular addition of a 5‐aminopenta‐2,4‐dienal onto a 2,3‐dihydropyridinium salt generated in situ (see scheme). In this way, a monomacrocyclic model, with the same relative stereochemistry as that of the natural product, was obtained.
据报道,一种生物仿生合成了海洋生物碱盐环己胺A的模型化合物,该过程涉及通过分子内添加5-氨基戊-2,4-二烯丙基到就地生成的2,3-二氢吡啶鎓盐上进行大环化(参见方案)。以此方式,获得了具有与天然产物相同的相对立体化学的单大环模型。
