Synthesis of 4-Quinolones through Nickel-Catalyzed Intramolecular Amination on the β-Carbon of o-(N-Alkylamino)propiophenones
摘要:
o-(N-Alkylamino)propiophenones are converted into 4-quinolones in the presence of chlorobenzene, potassium phosphate, morpholine, and nickel(0) catalyst. The reaction proceeds through the nickel-catalyzed formation of beta-enaminones from o-(N-alkylamino)propiophenones and morpholine, followed by the intramolecular transamination.
