A convenient and efficient C–OH bond activation, PdCl2(PPh3)2catalyzed, C–C bond formation of tautomerizable quinolinones with the aid of BOP reagent and boronic acids

An efficient, highly chemoselective PdCl2(PPh3)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 K2CO3/1,4-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.
