reported. This synthesis relies on a one pot regioselective aziridine ring-opening followed by intramolecular cyclization to install the cis-amino–alcohol pattern of jaspine B and on a modified Julia olefination of the lactone followed by a diastereoselective hydrogenation for the introduction of the C14 aliphatic chain. The separation of enantiomers in the course of this synthesis was achieved by
到jaspine B及其对映体A的快速访问ENT被报告从2,3-氮丙啶基-γ内酯-jaspine乙。这种合成依赖于一锅区域选择性氮丙啶开环,然后进行分子内环化,以安装茉莉花B的顺式-氨基-醇型;内酯经修饰的Julia烯化,然后通过非对映选择性氢化引入C14脂族链。在该合成过程中对映异构体的分离通过超临界流体色谱法实现。评价了两种对映异构体的细胞毒性。
