A Frontier in Indole Chemistry: 1-Hydroxyindoles, 1-Hydroxytryptamines, and 1-Hydroxytryptophans

  • Masanori SomeiEmail author
Part of the Topics in Heterocyclic Chemistry book series (TOPICS, volume 6)


Many new members of the 1-hydroxyindole, -tryptamine, and -tryptophan families are prepared. They demonstrate totally different reactivities from those of the corresponding indoles upon electrophilic substitution reactions. They also undergo nucleophilic substitution reactions that are unprecedented in indole chemistry. Doors to various kinds of new reactions and novel products open depending on the substrate structures and reaction conditions. 1-Hydroxyindoles, -tryptamines, and -tryptophans show a variety of biological activities, which makes this chemistry worth exploring for the development of new drugs.
