in medicinal chemistry, where they serve as bioisosteres of indoles or purines. Herein, we present a novel rhodium-catalyzed asymmetric 1,4-addition of arylboronic acids to 3-benzylidene-1H-pyrrolo[2,3-b]pyridin-2(3H)-ones, as these substrates are exocyclic methylene lactamyl Michael acceptors. Ten new original derivatives of 1H-pyrrolo[2,3-b]pyridin-2(3H)-one have been obtained.
7-氮杂吲哚是多用途的构建基块,尤其是在药物化学中,它们可作为吲哚或嘌呤的生物等排体。在本文中,我们介绍了一种新型的铑催化的芳基硼酸不对称的1,4-加成反应,将3-甲基亚苄基-1 H-吡咯并[2,3- b ]吡啶2-2 (3 H)-取代,因为这些底物是环外亚甲基内酰胺基迈克尔受体。获得了十个新的1 H-吡咯并[2,3 - b ]吡啶-2(3 H)-一的原始衍生物。
