Palladium‐Catalyzed Selective Carbofunctionalization of Inert γ‐C(sp3)−O Bonds with 4‐Hydroxypyridin‐2(1H)‐ones and 4‐Hydroxy‐2H‐pyran‐2‐ones

The palladium‐catalyzed selective carbofunctionalization of inert γ‐C(sp3)−O bonds of aliphatic amides by using the strategy of sp3 C−H activation/β‐O elimination/hydrocarbofunctionalization with the assistance of 8‐aminoquinolyl directing group is presented here. This method features a broad scope of both 4‐hydroxypyridin‐2(1H)‐ones and 4‐hydroxy‐2H‐pyran‐2‐ones, providing a versatile method for the synthesis of corresponding γ‐substituted amide derivatives. magnified image
