A highly efficient method to access unprotected C-3 bifunctional quaternary 3-allyl-3-(amino)oxindoles

Abstract

A highly efficient Rh(II) catalyzed non-radical protocol access to NH-free C-3 bifunctional oxindoles, which possess 3-allyl and 3-amino simultaneously, was first achieved by employing intermolecular [2,3]-sigmatropic rearrangement reaction between diazooxindoles...
