Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time."
The government has acted swiftly to the recommendations made by the Advisory Council on the Misuse of Drugs (ACMD) and we fully support the banning of 15 new synthetic opioids as Class A drugs.
