A number of 1-substituted 3,4-dihydro-9H-β-carboline derivatives (4) with high purity and yields have been synthesized by treating of tryptamine (1) with carboxylic acids (2) in polyphosphoric acid. 3,4-Dihydro-9Η-β-carbolines (4) were successfully transformed to 1,2,3,4-tetrahydro-9H-β-carbolines (5) and 9H-β-carbolines (6).
通过在多磷酸中用羧酸 (2) 处理色胺 (1) 合成了许多具有高纯度和收率的 1-取代的 3,4-二氢-9H-β-咔啉衍生物 (4)。3,4-二氢-9H-β-咔啉 (4) 成功转化为 1,2,3,4-四氢-9H-β-咔啉 (5) 和 9H-β-咔啉 (6)。
