Abstract
An organocatalyzed oxidative C-N bond formation of phenylpropanamide derivatives provides 3,3-disubstituted oxindole derivatives in very good yields. This highly efficient intramolecular reaction offers transition metal-free mild conditions and the ability to perform the reaction on a gram scale.
