  synthesis of isoquinolones from benzamides and alkynes via the oxidative ortho C−H activation of benzamides has been developed. Ag2CO3 proved to be an optimal oxidant when MeCN was used as a solvent, and [RhCp*Cl2]2 was utilized as an efficient catalyst. Both N-alkyl and N-aryl secondary benzamides can be applied as effective substrates. Furthermore, primary benzamides react with two alkyne units, leading

  已开发出一种方法，可通过苯甲酰胺的氧化邻位C-H活化从苯甲酰胺和炔烃高产且轻松地合成异喹诺酮。当以MeCN为溶剂和[RhCp * Cl 2 ] 2时，Ag 2 CO 3被证明是最佳氧化剂。被用作有效的催化剂。N-烷基和N-芳基仲苯甲酰胺都可以用作有效的底物。此外，一级苯甲酰胺与两个炔烃单元反应，通过双重CH活化和氧化偶合生成三环产物。还证明了与结构相关的1-羟基异喹啉的反应性，其中可以同时生成含N和O的rhodocyclic中间体，从而导致构建不同的含O或N的杂环。

  A simple and efficient approach for the preparation of substituted indoles and isoquinolones via a nickel-catalyzed Larock-type heteroannulation reaction is reported. This transformation employed air-stable and inexpensive Ni(dppp)Cl2 as a precatalyst and Et3N as a mild base. Moreover, the reaction occurs efficiently under mild conditions, and a wide range of substituted indoles and isoquinolones bearing

  日期：2017.11

  Pd/C-catalyzed direct synthesis of N-aryl and N-alkyl isoquinolones was developed via the annulation reactions of benzamides and alkynes in high yields (up to 99%) through the cleavage of CH/NH bonds. The reaction was ligand-free and air was used as oxidant. High regioselectivities were found when unsymmetrical alkynes or meta-benzamides were used as substrates. The heterocyclic carboxamide substrates
