- 5-Hydroxy-β-carboline 4 was synthesized and submitted to the Mannichreaction towards formaldehyde and some primary amines. It undergoes an original reaction of bis-aminomethylation-cyclisation giving the oxazinopyrimidocarboline derivatives 5a-d. The structure of these compounds was confirmed by their high-resolution mass, IR, 1 H NMR and 13 C NMR spectral data.
- 合成 5-Hydroxy-β-carboline 4 并进行 Mannich 反应,生成甲醛和一些伯胺。它经历双氨基甲基化环化的原始反应,得到恶嗪并嘧啶并咔啉衍生物 5a-d。这些化合物的结构通过它们的高分辨率质量、IR、1 H NMR 和 13 C NMR 光谱数据得到证实。
