The first stereoselectivesynthesis of Certonardolsterol D3 was described. Ene reaction and improved allylic oxidation were employed as key steps for efficient construction of the desired 3β,6α,15β-triol steroidal framework. The chiral side chain in Certonardolsterol D3 was finally introduced by Julia olefination.
描述了Certonardolsterol D 3的第一个立体选择性合成。烯反应和改进的烯丙基氧化被用作有效构建所需的3β,6α,15β-三醇甾体骨架的关键步骤。最后,通过朱莉娅烯化反应引入了Certonardolsterol D 3中的手性侧链。
