The preparation and stereochemical characterization of (+/-)-1,trans 2,6-trimethyl-4-phenyl-4-propionoxypiperidine hydrochloride and its (+)- and (-)-antipodes are described. The absolute configurations of the antipodes were established by X-ray analysis of the corresponding (-)-4-piperidinol hydrobromide. In antinociceptive tests on mice and rats, the (+)-2S,6S ester proved the more potent antipode
