Synthesis of optically active 3-substituted-3-aminooxindoles containing vicinal quaternary stereogenic centers was achieved using a quinine thiourea organocatalyst. α-Acetoxy-β-keto esters have been introduced as nucleophiles to undergo Mannich reaction with isatin imines for asymmetric organocatalysis.
