A novel catalytic asymmetric 1,2‐difunctionalization reaction of indolenines with α‐(benzothiazol‐2‐ylsulfonyl) carbonyl compounds was developed. By employing the strategy of Brønsted acid‐assisted chiral phosphoric acid catalysis, the Mannich addition/Smiles rearrangement cascade occurred smoothly and provided a new family of optically active 1,2‐difunctionalized 2‐substituted indolines in good yields and enantioselectivities.
