title: 7-Aza analogs of the analgetic agent azabicyclane. Synthesis and pharmacologic analysis.
abstract: Three 3,7-diazabicyclo[3.3.1]nonane derivatives (4) with a structural similarity to the analgetic agent azabicyclane (1) were prepared. The amino alcohol 4a was found to prefer a conformation wherein the six-membered ring to which the hydroxyl group is syn is in the boat form. These three compounds had increased basicity in comparison with 1 due to various forces stabilizing their monocationic states. Compounds 4a-c did not show analgetic activity at the dose levels tested.
