Abstract: 4a-phenyl and substituted phenyl 2,3,4,4a,5,6,7,7a-octahydro-1H-2-pyrindines having a 2-substituent are disclosed. Such compounds are useful as analgesic agents having mixed agonist and antagonist properties. The compounds can be prepared by reacting an amine with a 4-aryl-2,6-dioxocyclopenta[c]pyran, followed by reduction, or alternatively by alkylating a 4a-aryl-octahydro-1H-2-pyrindine at the 2-position.
