Irradiation of 5-benzyl-, 5-methoxymethyl-, and 5-allyl-substituted codeinones and morphinones with UV light (lambda 366 nm) leads to formation of the corresponding 18beta-phenyl, 18beta-methoxy, and 18beta-vinyl derivatives of 4,5alpha-epoxymethanomorphin-7-en-6-one.
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.
