Abstract
A copper-promoted direct C1-amination of pyrrolo[1,2-a]quinoxalines with N-fluorobenzenesulfonimide (NFSI) has been achieved. A series of C1-aminated pyrrolo[1,2-a]quinoxalines were obtained with broad substrate scope and good functional group tolerance. Gram-scale synthesis and further derivation of this aminated product were also investigated. Mechanism studies suggest that this reaction probably undergoes a free-radical process.
