4-Hydroxy-indole is substituted in the 5-, 5-hydroxy-indole in the 4-, 6-hydroxy-indole in the 7-, and 7-hydroxy-indole probably in the 6-position. The structures of the Mannich bases from 4-, 5- and 6-hydroxy-indole have been confirmed by comparison of the hydroxy-methyl-indoles obtained by reductive desamination with hydroxy-methyl-indoles prepared by unambiguous total synthesis.
已经研究了在曼尼希反应条件下羟基吲哚的反应性。亲电子侧链在每种情况下都在酚基的邻位进入。4-羟基-吲哚被取代在5-,5-羟基-吲哚中的4-,6-羟基-吲哚中的7和7-羟基吲哚可能在6-位。通过与通过明确的总合成制备的羟基甲基吲哚进行还原性脱氨作用而获得的羟基甲基吲哚相比,已经证实了4-,5-和6-羟基吲哚的曼尼希碱的结构。
