| Abstract: | Regioisomeric 5-amino- and 6-amino- 1,3-benzoxazole-4,7-diones were prepared from 2,6-diamino-4-methoxyphenol and 2-amino-5-methoxyresorcinol, respectively. These symmetrical precursors have the property to be antisymmetrical to each other with respect to their amino and hydroxy substituents. |
