in pharmaceuticals, drug candidates, ligands for transition metal catalysts, and other molecular functional materials, so efficient methods for the synthesis of these compounds are of significant value. We herein describe a selective strategy for the synthesis of poly-substituted pyridines and fluoroalkyl dihydropyrimidines based on C–F bond breaking of the anionically activated fluoroalkyl group.

氟氮杂杂环经常在药物,候选药物,过渡金属催化剂的配体和其他分子功能材料中发现,因此合成这些化合物的有效方法具有重要价值。我们在此描述了一种基于阴离子活化的氟代烷基的CF键断裂合成多取代吡啶和氟代烷基二氢嘧啶的选择性策略。通过这种多米诺骨牌工艺在无贵金属催化剂的条件下以高收率制备了一系列吡啶和二氢嘧啶,这使该方法成为氮杂杂环合成的有价值的补充。
