The isomerization of 1,2-diaryl-1, 1a-dihydroazirino[1,2-a]quinozalines into 3-aryl-2-benzylquinoxalines under the action of acids is considered. The structures of the compounds synthesized have been confirmed by IR and PMR spectroscopy. It has been shown that the center of protonation in the azirinoquinoxalines and the model 1,2-dihydro-2,3-diphenylquinoxaline is the nitrogen atom of the azomethine group.
