An enantioselective synthesis of mitosane core (-)-1 has been achieved. Key steps include a rapid assembly of a key eight-membered-ring intermediate employing ring-closing metathesis. Kinetic resolution of an advanced secondary alcohol was then accomplished by using a peptide-based asymmetric acyl transfer catalyst that was discovered from a parallel screen of catalyst candidates. Optically pure material
已经实现了对映体选择性合成米托烷核(-)-1。关键步骤包括采用闭环复分解快速组装关键的八元环中间体。然后通过使用基于肽的不对称酰基转移催化剂(从候选催化剂的平行筛选中发现)来实现高级仲醇的动力学拆分。然后将光学纯的材料转化为三聚氰胺核,这是选择性修饰的进一步研究的主题,以生产几种含有三聚硅氧烷环系统的取代化合物。
