Silver lining: Highly exo‐selective asymmetric [3+2] cycloaddition of α‐amino ester Schiff bases with activated olefins proceeds in the presence of AgHMDS/1. The α‐amino ester Schiff bases including those derived from aliphatic imines successfully reacted to afford the corresponding pyrrolidine derivatives in high yield with high exo‐ and enantioselectivities. EWG=electron‐withdrawing group, HMDS=
