项目摘要
Synthetic organic chemistry continues to be of highest importance within drug discovery and development, as well as medicinal chemistry. This led to increased interest in catalytic, enantioselective synthesis in recent years, particularly regarding difficult to access, quaternary stereocenters. Based on previous initial studies the research project will initially focus on developing an Iridium-catalyzed, intramolecular, asymmetric allylic alkylation reaction of 1,3-dicarbonyls. This would allow easy access to various carbocycles with vicinal quaternary-tertiary stereocenters. This new methodology is then to be applied to the total synthesis of Aquilarabietic Acid H, a novel natural compound that showed anti-depressant properties in initial studies. Further, the asymmetric, intramolecular reaction is then to be extended to substrates with carbocycle-containing allyl moieties. This would give easy access to polycyclic motifs commonly found in steroids and related pharmaceutical drugs.
合成有机化学在药物发现和开发以及药物化学中仍然具有最高的重要性。这导致近年来对催化的对映选择性合成的兴趣增加,特别是关于难以接近的季立体中心。基于以前的初步研究,该研究项目将首先集中于开发铱催化的,分子内的,不对称烯丙基烷基化反应的1,3-二羰基化合物。这将允许容易地获得具有邻位的季-叔立体中心的各种碳环。这种新的方法,然后被应用到Aquilarabietic酸H,一种新的天然化合物,在初步研究中显示出抗氧化性能的全合成。此外,然后将不对称的分子内反应扩展到具有含碳环的烯丙基部分的底物。这将很容易获得类固醇和相关药物中常见的多环基序。
