In an effort to find new leads as anticancer or antimicrobial agents, the present work deals with the synthesis of some novel 1-substituted 1,2,4-triazolo[4,3-a]quinoxalines 7, 9a,b, and 14–19 and 1,2,4-triazino[4,3-a]quinoxalines 10a–c as well as 2-[5-amino-3-(4-chlorophenyl)pyrazol-1-yl]-3-benzylquinoxaline 13. These were synthesized using the key intermediate 3-benzyl-2-hydrazinoquinoxaline 6 with
