摘要
A direct electrochemical redox reaction involving radical cross-coupling cyclization for the synthesis of pyrrolo[1,2-a]quinoxaline derivatives from 1-(2-aminophenyl)pyrroles and CH3CN has been developed, which includes the functionalization of C(sp(3))-H bonds as well as the construction of C-C and C-N bonds. Notably, the control and deuterium-labelling experiments suggest that CH3CN in this reaction acts as both a carbon source via C-C cleavage and solvent. The reaction features metal- and oxidant-free conditions, and various substituted pyrrolo[1,2-a]quinoxaline derivatives were obtained.
