Stereoselective synthesis of the (4R)-C1-C6 and (14R, 15R)-C9-C17 segments, 4 and 5 respectively, of amphidinolides O and P have been achieved starting from a common chiral precursor 6 which was obtained by radical-mediated opening of a trisubstituted epoxy alcohol using Cp2TiCl-cyclohexa-1,4-diene.
两栖类内酯 O 和 P 的 (4R)-C1-C6 和 (14R, 15R)-C9-C17 片段分别为 4 和 5 的立体选择性合成是从通过自由基介导获得的共同手性前体 6 开始实现的使用 Cp2TiCl-环己-1,4-二烯打开三取代环氧醇。
