Synthesis of Enantiomerically Enriched 3-Amino-2-oxindoles through a Palladium-Mediated Asymmetric Intramolecular Arylation of α-Ketimino Amides

A highly efficient and enantioselective synthesis of 3-amino-2-oxindoles through a palladium-catalyzed asymmetric intramolecular arylation of alpha-ketimino amides using (R)-DiFluorPhos as the coordinating ligand is reported. This report constitutes the first enantioselective palladium. catalyzed arylation of ketimines.
