The synthesis and pharmacological activity of a new series of 1-oxa-4,9-diazaspiro[5.5]undecane derivatives as potent dual ligands for the sigma-1 receptor (σ1R) and the μ-opioid receptor (MOR) are reported. The different positions of the central scaffold, designed using a merging strategy of both target pharmacophores, were explored using a versatile synthetic approach. Phenethyl derivatives in position 9, substituted pyridyl moieties in position 4 and small alkyl groups in position 2 provided the best profiles. One of the best compounds, 15au, showed a balanced dual profile (i.e., MOR agonism and sigma antagonism) and a potent analgesic activity, comparable to the MOR agonist oxycodone in the paw pressure test in mice. Contrary to oxycodone, as expected from the addition of σ1R antagonism, 15au showed local, peripheral activity in this test, which was reversed by the σ1R agonist PRE-084. At equianalgesic doses, 15au showed less constipation than oxycodone, providing evidence that dual MOR agonism and σ1R antagonism may be a useful strategy for obtaining potent and safer analgesics.

An approach to the preparation of 2-mono-, 2,2- and 2,3-disubstituted 1,4-dioxane derivatives is described. The reaction sequence commences from readily available epoxides, in most cases prepared via the Corey-Chaikovsky reaction of the corresponding aldehydes and ketones. The key step of the method is epoxide ring opening with ethylene glycol monosodium salt, followed by further cyclization of the diols obtained. The utility of the approach was demonstrated by multigram preparation of novel functionalized 1,4-dioxanes bearing additional cycloalkane, piperidine or pyrrolidine rings, mostly spirocyclic compounds, which are advanced building blocks for medicinal chemistry.
