The organocatalytic enantioselective trifluoromethylthiolation of oxindoles employing N-(trifluoromethylthio)phthalimide as a stable, easy to handle CF3S-source has been developed. Optically active products with a quaternary stereogenic center bearing a CF3S-group are obtained in good yields and with good to excellent enantioselectivities.
