Dehydration of N-unsubstituted-N-(2-ureidobenzoyl)-anthranilic acids 1 and 2 furnishes derivatives (10 and b), 4H-3,1-benzoxazin-4-one. The latter may subsequently be isomerized into quinazolin-2-on 16 and 19, respectively. The former may be further dehydrated to yield the quinazolino-[4.3-b]quinazoline-6,8-dione (17).
N-未取代的-N-(2-脲基苯甲酰基)-邻氨基苯甲酸1和2的脱水提供衍生物(10和b),4 H -3,1-苯并恶嗪-4-酮。后者随后可以分别异构化为喹唑啉-2-on 16和19。前者可以进一步脱水以产生喹唑啉基-[4.3-b]喹唑啉-6,8-二酮(17)。
