title: 2-Azabicyclo (2.2.2)octane analogues of the prodine analgetics.
abstract: The synthesis and analgetic activity of analogues of prodine-type analgetics in which the conformation of the piperidine ring is restricted in the boat form using the 2-azabicyclo (2.2.2)octane nucleus are reported. One of these analogues, 2-methyl-6-trans-phenyl-6-cis-propionoxy-2-azabicyclo (2.2.2)octane (3), showed significant analgetic activity (ED50 equals 3.1 mg/kg).
