The formal total synthesis of FR252921 is described. The key steps include the preparation of three fragments starting from 1,4-butanediol, (R)-malic acid, and prenol, respectively, followed by two consecutive peptide couplings of the three fragments. Other key steps involve an allene-type rearrangement or enyne isomerization to install the triene moiety, a Seebach methylation, a Julia olefination
描述了 FR252921 的正式全合成。关键步骤包括分别从 1,4-丁二醇、(R)-苹果酸和异戊烯醇开始制备三个片段,然后是三个片段的两个连续肽偶联。其他关键步骤包括丙二烯型重排或烯炔异构化以安装三烯部分、Seebach 甲基化、Julia 烯化以构建三取代二烯单元,以及酶促拆分策略以生成 C-18 立体中心。
