Method of preparing norbenzomorphane as an intermediate in the
preparation of pharmaceutically useful benzomorphane derivatives, in
particular
(-)-(1R,5S,2
摘要:
The present invention relates to new processes for preparing norbenzomorphan, the central intermediate step in the preparation of pharmaceutically useful benzomorphan derivatives of general formula 1 ##STR1## especially (-)-(1R,5S,2"R)-3'-hydroxy-2-(2-methoxypropyl)-5,9,9-trimethyl-6,7-benzomorphan or [(-)-(2R, 6S,2'R)-3-(2-methoxypropyl)-6,11,11-trimethyl-1,2,3,4,5,6-hexahydro-2,6-methano-benzo[.alpha.]oxacin-9-ol] (BIII 277).
