一种结构复杂的海洋抗肿瘤药物,从已知的醛中通过27步合成出了会聚的、立体控制的全合成方法8。该合成的亮点包括一个新颖高效的跨环Michael加成/内酯还原序列,以构建高取代的2,6-反式四氢吡喃;一个非对映选择性ibr诱导的碘碳酸环化反应,以引入C17立体中心;以及一个Diels-Alder /芳构化反应,以安装高取代的芳环。
A convergent, stereocontrolled total synthesis of psymberin, an architecturally complex marine antitumor agent, has been achieved in 27 steps from the known aldehyde8. Highlights of this synthesis include a novel and efficient transannular Michael addition/lactone reduction sequence to construct the highly substituted 2,6-trans-tetrahydropyran, a diastereoselective IBr-induced iodocarbonate cyclization to introduce the C17 stereogenic center, and a Diels–Alder/aromatization reaction to install the highly substituted aromatic ring.
