Esters of hexahydro-8-hydroxy-2,6-methano-2H-quinolizin-3 (4H) -ones and hexahydro-8-hydroxy-2,6-methano-2H-quinoliziner and pharmaceutically acceptable acid addition salts and quaternary ammonium salts thereof, method for their preparation, as well as an intermediate

摘要

The present invention is directed to a group of esters of hexahydro-8-hydroxy-2,6-methano-2H-quinolizin-3(4H)-one and related compounds. The compounds are prepared from the appropriate carboxylic acids and alcohols by standard procedures or, where steric factors are significant, a new process which makes use of heavy metal salts of super acids can be used. The compounds involved are useful in the treatment of migraine and similar disorders and in cytotoxic drug-induced vomiting.
