1,5-Di(hetero)arylated-pyridin-2(1H)-one derivatives have been readily obtained in good yields starting from 2-fluoro-5-pyridylboronic acid. The sequence comprises three steps: (i) palladium-catalysed Suzuki-Miyaura reaction; (ii) base-catalysed hydrolysis; (iii) copper-catalysed C–N coupling. X-ray crystal structures are reported for selected pyridin-2(1H)-one derivatives. These compounds are of interest
从2-氟-5-吡啶基硼酸开始容易地以高收率获得1,5-二(杂)芳基化吡啶-2-2(1 H)-one衍生物。该序列包括三个步骤:(i)钯催化的Suzuki-Miyaura反应;(ii)碱催化水解;(iii)铜催化的C–N耦合。报告了选定的吡啶-2(1 H)-one衍生物的X射线晶体结构。这些化合物作为用于药物发现的新支架是令人感兴趣的。
