The present disclosure generally relates to methods for producing opioid derivatives. More particularly, the present disclosure relates to the preparation of hydromorphone, hydrocodone, or a derivative thereof, by means of a non-catalytic hydrogenation reaction of thebaine, oripavine or a derivative thereof, respectively, using a hydrazide reagent, followed by hydrolysis of the hydrogenated intermediate at a low temperature and for a short period of time. Additionally, the present disclosure relates to a composition comprising the desired hydromorphone, hydrocodone, or a derivative thereof, in combination with a 6-beta compound that is structurally related thereto.
