A manganese‐catalyzed C−H annulation of ketimines with poly‐substituted ester‐activated allenes toward the synthesis of 1‐aminoindanes bearing two vicinal all‐substituted carbon stereocenters and an exocyclic double bond was developed. The reaction features high diastereoselectivity, high E/Z selectivity, 100% atom‐economy, broad substrate scope and good functional group tolerance.
