Reported herein is a bifunctional‐organocatalyst‐mediated enantioselective inverse‐electron‐demand 1,3‐dipolar cycloaddition of C,N‐cyclic azomethine imines with azlactones. The strategy provides concise access to enantioenriched C1‐substituted tetrahydroisoquinolines featuring a pyrazolidinone scaffold. Moreover, the scalability and practical utility of this protocol was well demonstrated by employing
