The first synthesis of squamostanal-A (1), separated as a degradation product of tetrahydrofuranic acetogenins, is described. Iodide 7, which corresponds to the latent aldehyde moiety of 1, was prepared through a 2-step sequence from 13-[tetrahydropyran-2'- yloxy]-2-tridecyn-l-ol (5). The NaHMDS-based coupling reaction of 7 with γ-lactone 8 gave compound 9, which by a 3-step sequence, was coverted to 1
本文描述了作为四氢呋喃苷元降解产物分离出来的角鲨烷-A(1)的首次合成。碘化物 7 与 1 的潜在醛基相对应,它是由 13-[四氢吡喃-2'-氧基]-2-十三炔-l-醇(5)通过两步法制备的。7 与γ-内酯 8 发生基于 NaHMDS 的偶联反应,得到化合物 9,并通过 3 步顺序将其转化为 1
