RESUMO
A simple and effective method for the synthesis of 3-aryl-3-substituted oxindole derivatives via a [Rh]-catalyzed three-component reaction of 3-diazooxindoles with N,N-disubstituted anilines and glyoxylates is developed. This transformation is proposed to proceed through an intermolecular aldol-type trapping of zwitterionic intermediates.
