has been established for total synthesis of the naturally occurring (–)‐palmyrolide A and (+)‐5,7‐epi‐palmyrolide A. By using the racemic tert‐butyl carbinol‐containing alkyl iodide, the two diastereoisomeric macrolides could be obtained from the same sequence of reactions, demonstrating the flexibility of the multimodule assembly strategy for diverted total synthesis.
已经建立了一种五模块组装方法,用于完全合成天然存在的(–)‐ palmyrolide A和(+)‐ 5,7 ‐ epi‐ palmyrolideA。通过使用外消旋叔丁基甲醇含有的烷基碘,这两种非对映异构体大环内酯类化合物可从相同的反应序列中获得,证明了多模块组装策略用于转移总合成的灵活性。
