cascade nucleophilic addition reactions of 1,2,3-triazines with activated acetonitriles or ketones, which were used to construct highly substituted pyridines that are not easily accessed by conventional methods. The strategy addressed some structural diversity issues currently facing medicinal chemistry, and the resulting pyridines could be used as convenient precursors for the synthesis of related pharmaceuticals
摘要我们研究了1,2,3-三嗪与活化乙腈或酮的级联亲核加成反应,该反应用于构建传统方法不易获得的高度取代的吡啶。该策略解决了药物化学目前面临的一些结构多样性问题,所得吡啶可用作合成相关药物的方便前体。特别是,我们的方法仅需几个步骤即可应用于市售药物依托考昔和几种生物学上重要的分子的合成。
