## Abstract **Amino sulfonamide catalyst**: A distal proton of the axially chiral amino sulfonamide (__S__)‐**1** realized the opposite diastereoselectivity in Mannich and cross‐aldol reactions compared with that observed in proline‐catalyzed reactions. The reactions catalyzed by (__S__)‐**1** proc
