Fragment-based lead generation has proven to be an effective means of identifying high-quality lead compounds for drug discovery programs. However, the fragment screening sets often used are principally comprised of sp(2) -rich aromatic compounds, which limits the structural (and hence biological) diversity of the library. Herein, we describe strategies for the synthesis of a series of partially saturated
事实证明,基于片段的线索生成是识别用于药物发现计划的高质量线索化合物的有效手段。但是,经常使用的片段筛选集主要由富含sp(2)的芳香族化合物组成,这限制了文库的结构(因而也具有生物学上的多样性)。在这里,我们描述了具有增强的sp(3)特性的一系列部分饱和的双环杂芳族支架的合成策略。随后的衍生化导致片段集合,其特征在于在饱和环系统上区域和立体控制地引入取代基,通常形成新的立体中心。
