Nitrone cycloaddition on a dearomatized bicyclic phenol enabled the facile construction of the correctly configured phenanthrene skeleton of codeine. Further steps yielded allopseudocodeine in a completely diastereoselective manner and finally (±)-codeine by allylic transposition through the hydrolysis of chlorocodides.

Process for converting neopinone to codeinone
-
, (2008/06/13)
A process for converting neopinone alkaloid to codeinone alkaloid which involves treating neopinone with a hydrohalic acid in a suitable solvent under anhydrous conditions. It also relates to the compound 8-halodihydrocodeinone hydrohalide.
