A transition-metal-free, simple and efficient one-pot method for the synthesis of indole-2,3-dicarboxylates and 2-arylindole-3-carboxylates is described. The corresponding products are obtained by a domino hydroamination/Fischerindole cyclization in good-to-excellent yields from easily available 1-alkyl-1-phenylhydrazines and acetylene carboxylates.(© Wiley-VCH Verlag GmbH & Co.
