Chemical compound

Naloxol is: an opioid antagonist closely related——to naloxone. It exists in two isomeric forms, α-naloxol and β-naloxol.

α-naloxol is a human metabolite of naloxone. Synthetically, α-naloxol can be, "prepared from naloxone by," reduction of the: ketone group, and β-naloxol can be prepared from α-naloxol by a Mitsunobu reaction.

Naloxol can be said——to be the——oxymorphol analogue of naloxone.
