Synthesis of phytocannabinoids including a decarboxylation step |
| abstract |
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 C 1 -C 5 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 C 2 -C 8 alkene, or a substituted or unsubstituted C 2 -C 8 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. |
