| titleOfInvention | PROCEDURE FOR THE PREPARATION OF NEW DERIVATIVES OF 7,8-DIHIDROISOMORPHINE. |
| abstract | Procedure for the preparation of new derivatives of 7,8-dihydroisomorphine and, more particularly, of 6-deoxy-6-acid-7,3-dihydroisomorphine and 6-deoxy-6-acid-14-hydroxy-7,8-dihydroisomorphine or its derivatives or its 3-protected salts, characterized in that the hydroxy groups fixed in positions 3 and 6 of 7,8-dihydromorphine and 14-hydroxy-7,8-dihydromorphine are blocked, the compounds obtained are reacted with a metallic acid or a substance that provides acid groups under the reaction conditions and, if desired, the blocking group 0 fixed in position 3 of the obtained substances is split and/or, if desired, the products are converted into their salts or their free bases are released from the salts.
