Targeted structural modifications have led to a novel type of buprenorphine-derived opioid receptor ligand displaying an improved selectivity profile for the μ-OR subtype. On this basis, it is shown that phenylazocarboxamides may serve as useful bioisosteric replacements for the widely occurring cinnamide units, without loss of OR binding affinity or subtype selectivity. This study further includes functional experiments pointing to weak partial agonist properties of the novel μ-OR ligands, as well as docking and metabolism experiments. Finally, the unique bifunctional character of phenylazocarboxylates, herein serving as precursors for the azocarboxamide subunit, was exploited to demonstrate the accessibility of an 18F-fluorinated analogue.

The cross-coupling reaction of 4-[18F]fluoroiodobenzene 3a with vinyl or aryl tin reagents in the presence of tetrakis(triphenylphosphine)palladium was found to provide a convenient and rapid method for the preparation of 4-[18F]fluorostyrene or 4-[18F]fluorobiphenyl within 45-50 min and 47% or 86% radiochemical yields, respectively, counted from 3a. (E)-N-{3-(4-[18F]fluorophenyl}prop-2-enyl]piperidine 2a was obtained within 45 min and in 80% radiochemical yield from 3a. 4-[18F]Fluorobromobenzene 4a was prepared in 24-48% yield from 2-nitro-5-bromobenzaldehyde and [18F]KF in 95 min.
