A series of N-substituted 7-azabicyclo[2.2.1]heptanes (12–17 and 22–25) and similarly substituted pyrrolidines (32–36 and 41–44) were synthesized as sterically-reduced, achiral analogs of adamantane- and trishomocubane-derived σ ligands. In vitro competition binding assays against σ receptors revealed that arylalkyl N-substituents conferred selectivity for the σ2 subtype, while alicyclic or polycarbocyclic
