Abstract Rhodium(III)-catalyzed synthesis of indole derivatives has been realized via cascade reaction of C H alkylation/nucleophilic cyclization starting from readily available N-phenylpyridin-2-amines and sulfoxonium ylides. Notably, this transformation could smoothly proceed with high yields, good regioselectivity, and feature broad group tolerance and under redox-neutral condition to avoid external

A study of the nucleophilic addition of amines to 2,3-pyridyne has been carried out. 2-Aminopyridines have been generated exclusively. A series of benzonaphthyridinones have been synthesized by reacting 2,3-pyridyne and o-aminobenzoates. (C) 2012 Elsevier Ltd. All rights reserved.

Iridium-Catalysed Cascade Synthesis of Oxindoles Using Diazo Compounds: A Quick Entry to C-7-Functionalized Oxindoles
A cascade iridium-catalysed oxindolesynthesis was achieved using pyridyl-protected anilines and bis(2,2,2-trifluoroethyl) 2-diazomalonate. The developed protocol is simple and scalable, and has a broad scope and excellent regioselectivity. The pyridyl directing group can easily be removed. The method was further extended to give C-7-functionalized oxindole derivatives in a straightforward manner.
