versatile methodology to synthesise 4-hydroxy-1H-[1,2,4]triazino[4,5-a]quinoline-1,6(2H)-dione from methyl 6-fluoro-4-oxo-1,4-dihydro-2-quinolinecarboxylate has been developed. It involves car-bohydrazide formation followed by a condensation with triphosgene to form the fused [1,2,4]triazino ring. In addition, the reactivity of the [1,2,4]triazino ring has been studied.
从甲基6-氟-4-氧代-合成4-羟基-1 H- [1,2,4]三嗪[4,5- a ]喹啉-1,6(2 H)-二酮的简单通用方法已经开发了1,4-二氢-2-喹啉羧酸酯。它涉及碳酰肼的形成,然后与三光气缩合以形成稠合的[1,2,4]三嗪基环。另外,已经研究了[1,2,4]三嗪基环的反应性。
