The 14-O-benzylnaltrexones 3–6 were prepared from naltrexone (2) in several steps. The novel compounds were biologicallyevaluated in radioligand binding and in [35S]GTPγS functional assays in comparison to the reference compound naltrexone. In the binding assay, compounds 3–6 exhibited preference for κ opioid receptors, while the parent compound naltrexone shows preference for μ receptors. In the
