Regioselective Functionalization of Quinolin‐4(1H)‐ones via Sequential Palladium‐Catalyzed Reactions.

A variety of 1,3,6-trisubstituted quinolinones of potential pharmaceutical activity is prepared starting from the corresponding N-alkyl-6-bromo-3-iodo-substituted quinolinones by sequential regioselective and microwave-assisted Suzuki—Miyaura, Sonogashira, or aminocarbonylation reactions (15 examples).
