The 7-oxabicyclo[2.2.1]heptene ring system is a common structural motif in many pharmacologically interesting molecules. We recognized the potential to employ this highly oxygenated and conformationally-restricted scaffold in diversity-oriented synthesis to generate a library of non-chiral but topologically complex compounds. Herein, we report the synthesis and biological evaluation of two 96-member tricyclic libraries containing the oxabicyclo[2.2.1]heptene framework using acetal formation as the key step.
7-氧杂双环[2.2.1]庚烯环系统是许多具有药理学意义分子中的常见结构基元。我们认识到,可以通过利用这种高度氧化的、构象受限的骨架,在定向多样性合成中生成一组非手性但拓扑结构复杂的化合物。本文中,我们报道了利用
缩醛化反应作为关键步骤,合成并
生物评估了两个包含96个成员的
三环化合物库,这两个库均含有氧杂双环[2.2.1]庚烯框架。
