In this study, a divergent and practical solid-phase parallel diversity-oriented synthesis (DOS) strategy was successfully applied for the construction of five discrete core skeletons embedded with privileged benzopyranyl substructure. The diversity of these core skeletons was expanded through the introduction of various substituents at the R, R(1), and R(2) positions from a single key intermediate
在这项研究中,发散和实用的固相平行分集定向合成(DOS)策略已成功地应用于构建五个嵌入有特权苯并吡喃基亚结构的离散核骨架。这些核心骨架的多样性通过在五个不同途径中的单个关键中间体在R,R(1)和R(2)位置处引入各种取代基而得到扩展。更重要的是,我们通过使用库到库的概念,通过核心骨架本身的转换来有效地最大化了分子多样性,并创建了具有相同构件的独特小分子集合。构建了一个434个成员的多杂环苯并吡喃文库,规模约为10 mg,具有进一步多样化的潜力。无需进一步纯化,
