Bis-1,2,4-triazolo[4,3-a:3′,4′-c]quinoxalines of pharmaceutical interest from 1,3-dipolar cycloaddition

New derivatives of the heterocyclic system 1,12,12a,12b-tetrahydrobis-1,2,4-triazolo[4,3-a:3′,4′-c]quinoxaline of pharmaceutical interest have been synthesized by 1,3-dipolar cycloaddition of arylnitrilimines to quinoxalines.
