Stereoselective total synthesis of palmyrolide A, a 15-membered neuroactive macrolide, was described by adopting a synthetic strategy developed for the proposed structures, and its 5,7-epi isomers. The strategy was designed in such a way that the set of stereoisomers, which were needed for establishing the absolute configuration of palmyrolide A, could be obtained from one time operation. The diastereoselective
通过采用针对所提出的结构及其5,7- epi异构体开发的合成策略,描述了具有15个成员的神经活性大环内酯类化合物pallyrolide A的立体选择性全合成。设计该策略的方式是,可以从一次操作中获得建立棕榈酰A的绝对构型所需的一组立体异构体。外-亚甲基-γ-丁内酯的非对映选择性加氢成α-甲基-γ-丁内酯,山口酯化和分子内脱水环化形成反式-烯酰胺是合成的关键步骤。
