Norcolaurine is converted into (S)-reticuline, which is then isomerised into (R)-reticuline; this undergoes successive cyclisations (ring-forming reactions) generating first salutaridine and then the alkaloid thebaine. Synthesis of thebaine. Subsequent steps generate codeine (and morphine). read more
