(NHC)-catalyzed formal [4 + 2] annulation of 2-aryl-3H-indol-3-ones with α,β-unsaturated carboxylicacids bearing γ-H was developed via an in situactivationstrategy. The reaction involves the γ-addition of vinyl enolates to the unique cyclic ketimines to afford chiral tricyclic indolin-3-ones with a quaternary carbon center at 2-position. This protocol provides a rapid and enantioselective pathway to
