Rhodium(III)-catalyzed CH amination of 2-arylquinazolin-4(3H)-one with N-alkyl-O-benzoyl-hydroxylamines

Add time:07/13/2019    Source:sciencedirect.com

N-benzoate alkylamines were used as the aminating agents, a efficient Rh-catalyzed ortho CH amination of 2-arylquinazolin-4(3H)-one has been reported. The reactions exhibit high efficient and good functional group tolerance. Exclusive 2,6-bis-aminated product and good to excellent yields were obtained under mild reaction conditions.
