A convenient and efficient C–OH bond activation, PdCl 2 (PPh 3 ) 2 catalyzed, C–C bond formation of tautomerizable quinolinones with the aid of BOP reagent and boronic acids

An efficient, highly chemoselective PdCl 2 (PPh 3 ) 2 catalyzed, C–C bond formation of tautomerizable quinolinones with various boronic acids via C–OH bond activation using benzotriazol-1-yloxytris(dimethylamino) phosphonium hexafluorophosphate (BOP) reagent in the presence of K 2 CO 3 /1,4-dioxane system under aqueous condition, leads to the formation of functionalized quinolines in excellent yields, which offers great utility advantages in the synthesis of interesting compounds.
