The diacetylated derivative of this compound easily crosses the blood-brain barrier before being converted to 6-MAM and this compound.
The Grewe cyclization is central to Kenner Rice's total synthesis of this compound, considered the only one remotely close to being synthetically viable. Robert Robinson's proposed structure for this compound was confirmed after its 1952 total synthesis by Marshall Gates. That synthesis of this compound saw an early synthetic use of the Diels-Alder reaction to form this compound's C-ring. This compound's biosynthesis begins from the benzylÂ·isoÂ·quinolone reticuline, whose R-isomer is converted to to salutaridine, then thebaine, which can be used to produce (*) thebacon. The diacetylated derivative of this compound easily crosses the blood-brain barrier before being converted to 6-MAM and this compound. Rearranging this compound results in the compound found in Dilaudid. Reacting pyridine with codeine demethylates it, resulting in this compound. For 10 points, name this potent analgesic, the primary component of opium.
