Abstract

A simple route to various N‐substituted 1‐amino‐1__H__‐indole‐3‐carboxylates by use of copper(I)‐catalyzed intramolecular N‐arylation has been established. For the preparation of N‐monosubstituted and N‐unsubstituted derivatives, the cyclization of Boc‐protected enehydrazines and subsequent deprotection were applied. Furthermore, 1‐alkoxyindole‐3‐carboxylates can be synthesized by use of the same protocol(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
