Synthesis of Fused Polycyclic Indoles by Brønsted Acid-Catalyzed Intramolecular Alkylation of Indoles with Alcohols

Abstract

An efficient methodology for the synthesis of a series of new fused polyclyclic indoles has been developed by Brønsted acidcatalyzed intramolecular Friedel−Crafts reactions of properly designed indolyl alcohols.
