Quinoxalines. XXVI. Synthesis of Bis-azolo[a,c]-fused Quinoxalines. I. Synthesis from 4-Substituted 1,2,3-Triazolo[1,5-a]quinoxalinesThe synthesis of bis-azolo-fused quinoxalines of type. 6 is described. The new bisazolo-fused compounds 9, 10a, b, 12, and 16 were synthesized from the 4-substituted 1,2,3-triazolo-[1,5-a]quinoxalines 7, 8, 11, and 13 by intramolecular cyclization reactions. The structures were determined by microanalysis, i.r., 1H-n.m.r., and mass spectra.
