2-溴-1, 4-二羟基蒽醌与氨基醇, 缩合可以生成2-取代氨基-1, 4-二羟基蒽醌, 但在较高温度下并延长反应时间, 部分产物可以进行分子内脱水而进一步环化为2, 3-二氢蒽并(1, 2-b)(1, 4)恶嗪-7, 12-二酮的衍生物。用MS和NMR确定其结构。

Condensation of 2-bromo-1, 4-dihydroxyanthraquinone with aminoalcohol af-fords initially 2-substitutedamino-1, 4-dihydroxy anthraquinone, which is then converted under more stringent reaction conditions into the ring closed 2, 3-dihydroanthra (1, 2-b)(1, 4) oxazine-7, 12-dione analogue. Their structures are confirmed by MS and NMR spectroscopy.

Key words: CONDENSATION REACTION, MASS SPECTROGRAPHY, AMINO ALCOHOL, NMR SPECTROMETRY, ANTHRAQUINONE P
