Abstract: | Quinoxalino[2,3-b]-1,4-thiazines were obtained by the reaction of 2-aminoquinoxaline-3-thione and its 6,7-dimethyl derivative with -halocarbonyl compounds. Hydrolysis of these compounds in alkaline and acid media gave 2-amino-3-quinoxalone and quinoxaline-2,3-dione. The IR and UV spectra are presented.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 853–856, June, 1971. |
