An enantioselective synthesis of the acyl side-chain 3 of polyoxypeptins 1 and 2 was achieved by the Sharpless AE, with subsequent regioselective opening of the epoxyalcohol using a Grignard reagent in the presence of CuI, and an aldol condensation using Seebach's ester. The method reported has the advantage of a concise route and excellent enantiomeric purity, as well as starting from readily available
通过Sharpless AE实现了对多氧肽1和2的酰基侧链3的对映选择性合成,随后在CuI存在下使用Grignard试剂对环氧醇进行了区域选择性开环,并使用Seebach酯进行了醛醇缩合。所报道的方法具有路线简洁和对映体纯度极佳的优点,以及从容易获得的化学底物和使用廉价试剂开始的优点。
