A fews representatives (1b-d) of a novel group of structurally related morphine-antagonist compounds have been prepared in stereochemically homogeneous form. The employed procedures involve O-demethylation either of the corresponding codeine derivatives 2b-d, or those of the N-alkylated analogues 2b,c, synthesized from N-demethylthebaine (7a) by means of N-alkylation and subsequent transformations of 7b,d, - compounds selected from the resulting functionalized thebaines 7b-e.
