AbstractOrganocatalyzed asymmetric phenylselenylation of 3-substituted oxindoles was achieved with chiral iminophosphoranes. A wide range of phenylselenylated oxindoles were synthesized in good to excellent yields (80–99%) and up to 97% ee under mild conditions. The procedure feathers simple separation and scale up to semi-gram without loss of enantioselectivity.
