Synthesis of Novel Morphinans From Thebaine [PDF]
, 1981 The synthesis of codeinone enol ethers from thebaine, via acetals of 14beta-bromocodeinone, has been successfully carried out. These enol ethers have, in turn, been converted into 6-alkoxy-6-desmethoxy-19-alkylthevinols, which have been shown to be ...

THEBAINE METABOLITES IN THE URINE OF RHESUS MONKEYS
Japanese Journal of Pharmacology, 1981 The metabolic fate of thebaine in rhesus monkeys was investigated. Using thin layer chromatography, more than four metabolites were detected in the urine of monkeys given thebaine (8 mg/kg, s.c.). Two of the metabolites isolated by high performance liquid chromatography were not consistent with those reported previously.
