Synthesis of 2-pyridones

Recent Literature

CuI-catalyzed coupling reactions of tetrabutylammonium pyridin-2-olates with aryl iodides allow an efficient synthesis of N-aryl pyridine-2-ones. This coupling reaction is mild, high-yielding, remarkably chemoselective (N- vs. O-arylation), and tolerates labile functional groups.
