The synthesis of three phenolic natural products has been accomplished with unprecedented efficiency using a new alumina-promoted regioselective aromatic allylation reaction. Cannabigerol and grifolin were prepared in one step from the inexpensive 5-alkyl-resorcinols olivetol and orcinol. Piperogalin was synthesized, for the first time, via two sequential allylations of orcinol with geraniol and prenol.

The spread of antimicrobial resistance continues to be a priority health concern worldwide, necessitating the exploration of alternative therapies. Cannabis sativa has long been known to contain antibacterial cannabinoids, but their potential to address antibiotic resistance has only been superficially investigated. Here, we show that cannabinoids exhibit antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA), inhibit its ability to form biofilms, and eradicate preformed biofilms and stationary phase cells persistent to antibiotics. We show that the mechanism of action of cannabigerol is through targeting the cytoplasmic membrane of Gram-positive bacteria and demonstrate in vivo efficacy of cannabigerol in a murine systemic infection model caused by MRSA. We also show that cannabinoids are effective against Gram-negative organisms whose outer membrane is permeabilized, where cannabigerol acts on the inner membrane. Finally, we demonstrate that cannabinoids work in combination with polymyxin B against multidrug resistant Gram-negative pathogens, revealing the broad-spectrum therapeutic potential for cannabinoids.

The present disclosure relates to cannabigerol sulfonate esters and processes for their use to prepare cannabigerol (CBG) and related compounds, including cannabigerobutol (CBGB), cannabigerovarin (CBGV), and cannabigerophorbol (CBGP). In a preferred embodiment, the cannabigerol sulfonate ester is (E)-4-(3, 7-5 dimethylocta-2,6-dienyl)-3,5-bis(trimetbylsilyloxy)phenyl trifluoromethanesulfonate. In a preferred process, the trifluoromethansulfonate leaving group is replaced by an alkyl group. The disclosure also relates to the use of catalysts and catalytic processes for the preparation of cannabigerol and related compounds from the cannabigerol sulfonate esters.
