| titleOfInvention | Synthesis of phytocannabinoids including a demethylation step |
| abstract | The invention relates to a method for the demethylation of a methylated phytocannabinoid compound of formula I to form a phytocannabinoid compound of formula II: formula I formula II, wherein: R 1 is selected from the group consisting of: C5 substituted or unsubstituted; R2 is selected from the group consisting of: OH or O, and R3 is selected from the group consisting of: substituted or unsubstituted cyclohexene, substituted or unsubstituted C2-C8 alkene, or substituted C2-C8 dialkene or unsubstituted; or R2 is O, and R2 and R3 together form a ring structure in which R2 is an internal nuclear atom; the method comprising: heating a reaction mixture comprising the methylated phytocannabinoid compounds and a polar aprotic solvent in the presence of a dissolved inorganic alkali metal salt for a time sufficient to demethylate at least a portion of the methylated phytocannabinoid compounds and form the phytocannabinoid compound. |
