A series of racemic N-arylalkyl-2-azaadamantan-1-ols (9-15) and the corresponding deoxygenated, achiral N-arylalkyl-2-azaadamantanes (23-29) were synthesized and screened in competition binding assays against a panel of CNS targets. Adamantyl hemiaminals 9-15 displayed generally low affinity for both sigma(1) (K-i values = 294-1950 nM) and sigma(2) receptors (K-i values = 201-1020 nM), and negligible affinity for 42 other CNS proteins. Deoxygenation of 9-15 to give the corresponding achiral azaadamantanes 23-29 greatly improved affinity for sigma(1) (K-i values = 8.3-239 nM) and sigma(2) receptors (K-i values = 34-312 nM).
