New chemistry to support the search for more effective opioidsTools Yang, Ruoyan (2020) New chemistry to support the search for more effective opioids. MSc(Res) thesis, University of Nottingham.
AbstractHerein is presented a synthesis route to obtain noroxymorphone, a vital intermediate in the manufacture of opioid medicines, using the major ingredient in opium – morphine as the starting material. Two steps of Albright-Goldman oxidation and the formation of diene are combined in one pot to enhance the efficiency of the whole route. The overall 14% yield is still impractical for industry. However, further optimization of Albright-Goldman oxidation can increase the yield to near 30% in total. Noroxymorphone is employed as a starting material to access new opioid derivatives by N-substitution or conjugate addition of amines onto electron-deficient alkenes.
