details of the total syntheses of the initially reported and revised structures of the neuroprotective agent palmyrolide A are reported. The key macrocyclization step was achieved using a sequential ring-closing metathesis/olefin isomerization reaction. Furthermore, the total synthesis of the related macrolide (2S)-sanctolide A is reported. The synthesis used key elements from the synthesis of palmyrolide
报道了神经保护剂棕榈酰吡咯烷酮A的最初报道和修改的结构的全部合成的全部细节。关键的大环化步骤是使用顺序的闭环复分解/烯烃异构化反应实现的。此外,已经报道了相关的大环内酯(2S)-三萜内酯A的全合成。合成过程中使用了棕榈油酸酯A合成中的关键元素,包括RCM /烯烃异构化序列。本文所述的合成工作用于促进天然产物Sanctolide A的立体化学分配,并证明了该方法在合成大环叔烯酰胺天然产物中的效用。
