Abstract

The preparation and stereochemical characterization of alpha- and beta-isomers of 1,2-dimethyl-4-m-hydroxyphenyl-4-propionyloxypiperidine are described. Both the alpha (axial 4-aryl/chair) and beta (equatorial 4-aryl/chair) isomers were of low potency or inactive in mice antinociceptive tests. Shortcomings of the alpha-isomer as a model for the 4-arylpiperidine moiety of morphine are discussed.
