SYNTHESIS OF PHYTOCANNABINOIDS INCLUDING A DECARBOXYLATION STEP
method for decarboxylating a carboxylated phytocannabinoid compound of Formula I to form a phytocannabinoid compound of Formula II: Formula I Formula II wherein: R1 is selected from the group consisting of: substituted or unsubstituted C1-C5 alkyl; R2 is selected from the group consisting of: OH or O, and R3 is selected from the group consisting of: a substituted or unsubstituted cyclohexene, a substituted or unsubstituted C2-C8 alkene, or a substituted or unsubstituted C2-C8 dialkene; or R2 is O, and R2 and R3 together form a ring structure in which R2 is an internal ring atom; wherein the method includes heating a reaction mixture comprising the carboxylated phytocannabinoid compound and a polar aprotic solvent in the presence of a LiCl for a time sufficient to decarboxylate at least a portion of the carboxylated phytocannabinoid compounds and form the phytocannabinoid compound.

SYNTHESIS OF PHYTOCANNABINOIDS INCLUDING A DEMETHYLATION STEP
A method for demethylating a methylated phytocannabinoid compound of Formula I to form a phytocannabinoid compound of Formula II: Formula I Formula II wherein: R1 is selected from the group consisting of: substituted or unsubstituted C1-C5 alkyl; R2 is selected from the group consisting of: OH or O, and R3 is selected from the group consisting of: a substituted or unsubstituted cyclohexene, a substituted or unsubstituted C2-C8 alkene, or a substituted or unsubstituted C2-C8 dialkene; or R2 is O, and R2 and R3 together form a ring structure in which R2 is an internal ring atom; wherein the method includes: heating a reaction mixture comprising the methylated phytocannabinoid compounds and a polar aprotic solvent in the presence of a dissolved inorganic alkaline salt for a time sufficient to demethylate at least a portion of the methylated phytocannabinoid compounds and form the phytocannabinoid compound.
