Syntheses, analgetic activity and physical dependence capacity of 5-phenyl-6,7-benzomorphan derivatives

Abstract
Observations made during the Stevens'' rearrangement of 1-benzyl-1-methyl-.DELTA.3-piperidinium salt derivatives under various conditions are discussed. The absolute configuration of the 9-demethyl series and the 2''-deoxy series is established. A convenient synthesis of 3H-labeled phenols using 3H3PO4 is described, as well as the preparation of 14C-labeled compounds by conventional methods. Analgetic activity and physical dependence was examined in mice.
