An efficient method for the synthesis of isoquinolones through base KOtBu-promoted SNAr reaction of 2-halobenzonitriles with ketones followed by Lewis acid Cu(OAc)2-catalyzed cyclization is described. Isoquinolone derivatives were obtained in satisfactory to good yields.
描述了一种有效的方法,该方法通过2-卤代苄腈与酮的碱式KO t Bu促进的S N Ar反应,然后由路易斯酸Cu(OAc)2催化的环化来合成异喹诺酮。以令人满意的至良好的产率获得了异喹诺酮衍生物。
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.

A convenient method is proposed for the synthesis of isoquinolone derivatives from 2-methylaryl aldehydes and nitriles through LiN(SiMe3)2/KOtBu-promoted formal [4 + 2] cycloaddition reaction, featuring high atomic economy, good functional group tolerance, and easy operation. It enables the efficient formation of new C–C and C–N bonds toward isoquinolones without using preactivated amides.

A new Cp*Ir‐catalyzed C–H arylation of 1‐isoquinolinone and 2 pyridones to afford 6‐phenylpyridin‐2(1H)‐ones and 3‐phenylisoquinolin‐1(2H)‐ones by using arylsilanes is described in this paper. This protocol offers significant synthetic advantages, including mild reaction conditions, good functional group tolerance, a wide range of substrate applicability, and a concise approach to the core structure
