simultaneous asymmetric Mannichreaction and the construction of axially chiral sulfone-containing styrenes in one pot from α-amidosulfones based on the waste–reuse strategy was demonstrated. A series of chiral β-amino diesters and axially chiral sulfone-containing styrenes with various functional groups were synthesized in good to excellent yields and enantioselectivities under mild conditions.
