Abstract

Substituted tricyclic or tetracyclic quinoxalines, tricyclic pyridoquinoxalines and bis-quinoxalines were synthesized in high yields starting from cyclic ketones by the α-bromination of cyclic ketones with N-bromosuccinimide (NBS) followed by condensation of the resulting α-bromo ketones with 1,2-diaminobenzene, 3,4-diaminopyridine, or 3,3′-diaminobenzidine.
