摘要

The development of a Michael/cyclization cascade reaction between 3-isothiocyanato-oxindoles and maleimide catalyzed by chrial squaramides is reported. This protocol provides a series of pyrrolidonyl spirooxindoles bearing three contiguous stereocenters in excellent yields (up to 99 %) with high diastereo- and enantioselectivities (up to >99:1 dr, 91 % ee).
