Abstract: The invention is directed to processes for the preparation of benzhydrocodone hydrochloride. More particularly, the invention is directed to processes for a one-pot synthesis of benzhydrocodone hydrochloride of improved yield and/or purity.
Abstract: An invention includes a process for the preparation of (S)-2((4R,4aS,6R,7R,7aR,12bS)-7,9-dimethoxy-1,2,3,4,5,6,7,7a-octahydro-4a,7-ethano-4,12-methanobenzofuro[3,2-e]isoquinolin-6-yl)-3,3-dimethylbutan-2-ol.
Abstract: The present invention relates to processes useful in the preparation of morphine analogs and derivatives, such as naltrexone, naloxone and nalbuphine and intermediates in the synthesis of said morphine analogs and derivatives. In a particular example, the process begins with for example oxymorphone, oxycodone, 14-hydroxycodeinone or 14-hydroxymorphinone, and includes the formation of an oxazolidine-containing intermediate using catalytic oxidation.

Abstract: The present disclosure relates to the preparation of a cannabidiol compound or a derivative thereof. The cannabidiol compound or derivatives thereof can be prepared by an acid-catalyzed reaction of a suitably selected and substituted di-halo-olivetol or derivative thereof with a suitably selected and substituted cyclic alkene to produce a dihalo-cannabidiol compound or derivative thereof. The dihalo-cannabidiol compound or derivative thereof can be produced in high yield, high stereospecificity, or both. It can then be converted under reducing conditions to a cannabidiol compound or derivatives thereof.
