Abstract

AbstractChemodivergent cycloadditions of azomethine ylides with diphenylcyclopropenone involving either Cu-catalyzed [3+3] or Ag-catalyzed [3+2] processes have been developed. These transformations provide a highly efficient method for the preparation of a variety of aromatic substituted dihydropyridinones and dihydropyrrolones with excellent regio and diasteroselectivities.
