The palladium-catalyzed, two-step, one-pot borylation/Suzuki coupling (BSC) reaction was developed to synthesize sterically hindered 2,2'-disubstituted biphenyl and phenyl-indole compounds in a short, simple, and efficient manner from two easily accessible aryl halides. High yields can be obtained by choosing properly both components according to their rough electronic properties. The illustration
开发了钯催化的两步一锅法硼化/铃木偶联(BSC)反应,以短短,简单和有效的方式从两个容易的位置合成空间位阻的2,2'-二取代联苯和苯基吲哚化合物可及的芳基卤化物。高的产率可通过根据它们的粗糙电子性质适当选择这两种组分来获得。通过七元或八元联苯内酰胺5a-e和paullone 3a的溶液和固相合成,提供了该方法实用性的说明。这些化合物尽管具有明显的细胞毒性,但仍具有中等程度的毒性,并可作为未来药物化学发展的结构模型。
