  • Patent number: 4175197
    Abstract: Novel 1,3,4-trisubstituted-4-arylpiperidines are prepared by alkylating a 2,3-disubstituted-3-arylpyrroline to afford a 1,2,3-trisubstituted-3-aryl-1-pyrrolinium salt, reacting the salt with diazomethane to provide a 1,2,3-trisubstituted-3-aryl-1,2-methylene-pyrrolidinium salt, heating the pyrrolidinium salt to effect a ring expansion to the corresponding 1,3,4-trisubstituted-4-aryl-1,4,5,6-tetrahydropyridinium salt, neutralizing the salt and reducing the tetrahydropyridine to provide a 1,3,4-trisubstituted-4-arylpiperidine. The piperidines so formed are useful as pharmacological agents and as intermediates in the preparation of other piperidines of the invention. The compounds provided herein are especially useful as narcotic agonists analgesics and as narcotic antagonists.
