An efficient zinc(II)‐catalyzed alkyne oxidation/CH functionalization sequence was developed, thus leading to highly site‐selective synthesis of a variety of isoquinolones and β‐carbolines. Importantly, in contrast to the well‐established gold‐catalyzed intermolecular alkyne oxidation, over‐oxidation can be completely suppressed in this system and the reaction most likely proceeds by a Friedel–Crafts‐type
一种有效的锌(II) -催化的炔氧化/ C ħ官能序列被开发,因此导致多种异喹诺酮和β咔啉的高度位点选择性合成。重要的是,与公认的金催化的分子间炔烃氧化相反,该体系中的过氧化可以被完全抑制,并且反应很可能通过Friedel-Crafts型途径进行。描述了力学研究和理论计算。
