4-diazepane analogs of N-(2-benzofuranyl)methyl-N′-(4-alkoxybenzyl)piperazines were prepared to explore the effect of ringcontraction and expansion on σ receptor affinity and subtype selectivity within a series of cyclic diamines. In vitro receptor binding assays revealed that all cyclic vicinal diamines possessed affinity and selectivity for σ1 receptors. The imidazolidines possessed nanomolar σ1 affinities
