    • 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.
    • 通过烷基化2,3-二取代-3-芳基吡咯啉得到1,2,3-三取代-3-芳基-1-吡咯啉鎓盐,制备新的1,3,4-三取代-4-芳基哌啶,使该盐与 重氮甲烷,得到1,2,3-三取代-3-芳基-1,2-亚甲基 - 吡咯烷鎓盐,加热吡咯烷鎓盐进行环扩展至相应的1,3,4-三取代-4-芳基-1 4,5,6-四氢吡啶鎓盐,中和盐并还原四氢吡啶,得到1,3,4-三取代-4-芳基哌啶。 如此形成的哌啶可用作药理学剂和作为制备本发明的其它哌啶的中间体。 本文提供的化合物特别用作麻醉剂激动剂止痛剂和麻醉拮抗剂。
