| Abstract: | The interaction of 1,3-disubstituted-5-bromo-2-thioxo-barbituric acid with o-aminothiophenols and o-aminophenol affords 5, 7-disubstituted-8-oxo-6-thioxo-pyrimido[5, 4-b](l, 4) benzothiazines and 5,7-disubstituted-8-oxo-6-thioxo-pyrimido[5,4-b] (1,4)-benzoxazines, respectively. The reaction of 5, 5-dibromo-1,3-disubstituted-2-thioxo-barbituric acid, with o-amino-thiophenols and o-aminophenol is discussed. The compounds have been characterised by chemical reactions and spectral studies. |
