Morphine alkaloids, part 114. A stereohomogeneous synthesis of N-demethyl-N-substituted-14-hydroxydihydromorphines
摘要:
A new route for the stereohomogeneous synthesis of N-demethyl-N-substituted-14-hydroxydihydromorphines 2 a - f has been elaborated, involving O-demethylation of the novel dihydrocodeine derivatives 6 a - f, obtained upon alkylation of the hitherto unknown N-demethyl-14-hydroxydihydrocodeine (5).
