method involves a copper-catalyzed tandem radical addition/cyclization of N- arylacrylamides with the alkyl radicals generated from isocyanides. Two C–C bonds are formed in a single step.
A novel and efficient protocol for the synthesis of 3,3-dialkylated oxindoles is described. The method involves a copper-catalyzed tandem radical addition/cyclization of N-arylacrylamides with the alkyl radicals generated from isocyanides. Two C–C bonds are formed in a single step.
