The arylcyclopropane motif as the combination of aryl and cyclopropyl ring systems can be found in an increasing amount of approved and investigational drugs. Herein, we have developed a mild, efficient nickel-catalyzed reductive cross-coupling protocol, featuring a simple Ni(II) precatalyst, a novel picolinamide NN2 pincer ligand. Notably, the reaction is tolerant of a broad range of functionalities
芳基环丙烷基序作为芳基和环丙基环系统的组合,可以在越来越多的批准和研究药物中找到。在此,我们开发了一种温和、高效的镍催化还原交叉偶联方案,其特点是一种简单的 Ni(II) 预催化剂,一种新型吡啶酰胺 NN 2钳形配体。值得注意的是,该反应对包括游离胺在内的广泛功能具有耐受性。
