Synthesis of Functionalized Isoquinolin-1(2<i>H</i>)-ones by Copper-Catalyzed α-Arylation of Ketones with 2-Halobenzamides
Copper is key: A concise route to isoquinolin‐1(2H)‐ones from simple and readily available starting materials is provided by an efficient copper‐catalyzed annulation of ketones with 2‐halobenzamides. The method is applicable to a wide range of ketones containing different functional groups furnishing the products in moderate to excellent yields.
Compounds capable of inhibiting replication of the hepatitis C virus (“HCV”) are described. This invention also relates to processes of making such compounds, compositions comprising such compounds, and methods of using such compounds to treat HCV infection.
