摘要:
A tertiary amino-thiourea catalyzed asymmetric aldol reaction between 2-isocyanatomalonate esters and isatins has been achieved. Optical active spirooxazolidinone oxindole derivatives could be obtained with excellent yields (80%-96%) and enantioselectivities (67%-99% ee) under mild conditions, providing an updated example to apply isatins as the electrophile in the asymmetric aldol reaction with 2-isocyanatomalonate esters.
