Synthesis of 5-Methoxymethyl, 5-(2-Methoxyethyl), and 5-Allyl Thebaine, Codeinone, and Morphinone Derivatives
摘要:
Simple routes to 5-methoxymethylthebaine, 5-(2-methoxyethyl)thebaine, 5-allylthebaine, and similarly substituted codeinones and morphinones are described.

5β- versus 7-benzyl products and the deviation of the electronic structure of ringC of 7-benzyl products. The acid-catalyzed rearrangement of morphinan-5,8-dienes, 5,6- and 6,7-disubstituted morphinan-6,8-dienes was achieved and mechanistic interpretations for the formation of new, potentially dopamine-active aporphines were provided.
