摘要：

An asymmetric cascade Mannich/cyclization reaction between 3-isothiocyanato oxindoles and sulfimides using a commercially available organocatalyst has been developed. A wide range of structurally diverse spiro[imidazolidine-4,3'-oxindole] derivatives were obtained with good yields (up to 92%) and excellent enantioselectivities (up to 99% ee).
