SYNTHESES OF CODEINE DERIVATIVES AND OTHER 3-O-ALKYLMORPHINS AND INTERMEDIATE COMPOUNDS USED THEREOF |
| abstract |
THE INVENTION CONCERNS THE SYNTHESIS OF DERIVATIVES OF CODEINE AND OTHER 3-0-ALKYLMORPHINES. A 14-OH GROUP IS INTRODUCED INTO A MORPHINANE BY REACTION OF SINGLE OXYGEN WITH A NEW DIENOL-ESTER OF A N-SUBSTITUENT-3-O-ALKYLNORMORPHINONE. THE COMPOUND OBTAINED IS ALSO A NEW COMPOUND WHICH CAN BE TRANSFORMED INTO NOROXYMORPHONE BY SUCCESSIVE OPERATIONS OF CATALYTIC HYDROGENATION, HYDROLYTIC REMOVAL OF THE SUBSTITUTE OF NITROGEN AND HYDROLYSIS AND O-DEALKYLATION. THE INTERMEDIATE DIENOL ESTER IS PREPARED BY N-DEMETHYLATION OF CODEINE OR ANOTHER 3-O-ALKYLMORPHINE FOLLOWED BY OXIDATION AND ESTERIFICATION OF THE OXIDIZED PRODUCT WITH AN ANHYDRIDE OR AN ACID HALOGENIDE . 14-HYDROXYMORPHINANS ARE STRONG ANALGESICS AND ANTAGONISTS OF NARCOTICS. |
