| titleOfInvention | Process for the production of cannabinoids |
| abstract | A process for the preparation of substantially pure diverse known and novel cannabinoids 1 and 2, which include Δ9-tetrahydrocannabinol (7), tetrahydrocannabivarin (9), cannabidiol (11), cannabidivarin (12) and other naturally occurring tetracyclic and tricyclic cannabinoids and other synthetic tetracyclic and tricyclic analogues, via intermediates 3, 6, 4 and 5, using a cascade sequence of allylic rearrangement, aromatization and, for the tetracyclic cannabinoids, further highly stereoselective and regioselective cyclization. These synthesized cannabinoids can more easily be obtained at high purity levels than cannabinoids isolated or synthesized via known methods. The cannabinoids 2, including Δ9-tetrahydrocannabinol (7), tetrahydrocannabivarin (9), are obtained containing very low levels of isomeric cannabinoids such as the undesirable Δ8- tetrahydrocannabinol. The known and novel analogues with variation in aromatic ring substituents, whilst easily synthesized with the new methodology, would be much more difficult to make from any of the components of cannabis or cannabis oil. |
