Abstract
3-Sulfonylmethylquinoxalin-2(1H)-ones 2a,b were used for the synthesis of the 2-thioxo 3a,b and 2–hydrazino 8a,b derivatives. The alkyl-thio derivatives 4–7 were obtained from 3a,b. 8a,b were condensed or cyclocondensed with the appropriate reagents to give the hydrazones 9–11. triazolo[4,3-a]quinoxalines 13–16, tetrazolo[1,5-a]quinoxalines 17 and triazino[4,3-a]quinoxalines 12. The quinox-aiino[2,1-b]quinazoline 20 was obtained from 4a and anthranilic acid.
