    Description / Table of Contents: Zusammenfassung Es wurde ein neuer Weg für die Darstellung von N-Demethyl-N-Substituierten-14-Hydroxydihydromorphinen2 a – f in stereochemisch einheitlicher Form ausgearbeitet. Diese erfolgte durch die O-Demethylierung der neuen Dihydrocodein-Derivate6 a – f, die durch N-Alkylierung des neuen N-Demethyl-14-hydroxycodeins hergestellt wurden.
    Notes: Summary A new route for the stereohomogeneous synthesis of N-demethyl-N-substituted-14-hydroxydihydromorphines2 a – f has been elaborated, involving O-demethylation of the novel dihydrocodeine derivatives6 a – f, obtained upon alkylation of the hitherto unknown N-demethyl-14-hydroxydihydrocodeine (5).
