Description

technical field [0001] The invention relates to the field of organic synthesis, in particular to a method for synthesizing 10-carbonyl / hydroxymorphine-6-glucuronide. Background technique [0002] Morphine-6-glucuronide (M6G) is the main metabolite of morphine, and its mechanism of action is similar to that of other opioids. It is a central nervous system μ-receptor opioid agonist. Compared with morphine, the analgesic effect of M6G is slower but lasts longer, and the side effects are milder, especially the incidence of nausea, vomiting and respiratory depression is lower. In addition, since morphine glucuronide is not metabolized by the liver, compared with other opioids, it has obvious advantages for patients with hepatic insufficiency. The structural formula is as follows: [0003] [0004] M6G itself is relatively stable, but it can be oxidized in aqueous solution. The oxidation reaction is a free radical reaction. Oxygen in the air, sunlight, ultraviolet radiation or...
