A versatile copper-catalyzed coupling reaction of pyridin-2(1H)-ones with aryl halides
摘要:
A robust method has been developed to couple a wide variety of pyridin-2-ones and aryl halides. This C-N bond forming reaction makes use of catalytic copper(I) iodide and the ligand 8-hydroxyquinoline. These conditions tolerate a wide degree of functionality on both the aryl halide and pyridin-2-one reactants and have resulted in numerous examples being synthesized. (c) 2006 Elsevier Ltd.

A Pd(II)-catalyzed straightforward oxidative naphthylation of unmasked 2-pyridone derivatives is described using a twofold internal alkyne as a coupling partner. The reaction proceeds through N–H/C–H activation to provide polyarylated N-naphthyl 2-pyridones. An unusual oxidative annulation at the arene C–H bond of the diarylalkyne leads to the formation of polyarylated N-naphthyl 2-pyridones, where

The hetero - Diels-Alder reaction of 3-(N-acetylbenzylamino)-2-cyano-1-phenyl-2-propen-1-one (3) with enol ethers (4) leads to diastereoisomeric cycloadducts 5 and 6 in good yields. The structure of the products is discussed in terms of configuration and preferred conformation. Reaction of 5 with sulfuric acid yields 3-benzoyl-1,2-dihydropyridin-2-one (7).
