An efficient, enantioselective synthesis of apoptolidinone has been completed, demonstrating the versatility of thiazolidinethione auxiliaries. Three propionate aldol additions and two asymmetric glycolate alkylations function to establish 8 of the 12 stereogenic carbon centers. A cross-metathesis reaction is utilized to assemble the C1-C10 trieneoate fragment and the C11-C28 polypropionate region
已经完成了一种高效的、对映选择性合成的apoptolidinone,证明了噻唑烷硫酮助剂的多功能性。三个丙酸醛醇加成和两个不对称乙醇酸烷基化作用建立 12 个立体碳中心中的 8 个。交叉复分解反应用于组装分子的 C1-C10 三烯酸酯片段和 C11-C28 聚丙酸酯区域。
