Photooxidation of thebaine. A route to 14-hydroxymorphinones and hydrodibenzofuran analogs of methadone
摘要:
The photooxidation of thebaine (1) produces a highly functionalized hydrodibenzofuran 2 via formation of the endoperoxide and a tert-amine radical cation. Photooxidation of the quaternary ammonium salt of thebaine 6, allows the isolation of the endoperoxide 7. Photooxidation of thebaine 1 in acidic medium (TFA), yields 14-hydroxycodeinone salt 3 via the corresponding endoperoxide.
