Process for the production of cannabinoids

A process for the preparation of substantially pure diverse known and novel cannabinoids 1 and 2, which include Δ.sup.9-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 Δ.sup.9-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.

Facile and selective perfluoro- and polyfluoroarylation of Meldrum's acid

This disclosure relates generally to the facile and selective mono-perfluoro and poly-fluoroarylation of Meldrum's acid to generate a versatile synthon for highly fluorinated alpha-phenyl acetic acid derivatives which provide straightforward access to fluorinated building blocks. The reaction takes place quickly and all products were isolated without the need for chromatography. An embodiment provides an alternative strategy to access alpha-arylated Meldrum's acids which avoids the need for aryl-Pb(IV) salts or diaryliodonium salts and provides access to the tertiary product which was not previously synthetically accessible. The synthetic versatility and utility of the Meldrum's acid products is demonstrated by subjecting the products to several derivatizations of the Meldrum's acid products as well as photocatalytic hydrodefluorination which provide access to difficult but valuable synthetic targets such as multifluorinated aromatics.

Applications of Known and Novel Cannabinoids
20210236460 · 2021-08-05 ·

The use of a medicament as a single agent, binary agent, or other combination comprising of substantially pure novel cannabinoids 1 and 2, optionally admixed with one or more known and novel cannabinoids and other known naturally occurring and synthetic tetracyclic 2A and tricyclic 1A cannabinoids for the prevention, treatment or cure of inflammatory mediated diseases or inflammatory mediated pathological conditions, anorexia, arthritis, cancer, pain, glaucoma, migraine, persistent muscle spasms, seizures (epileptic seizures), severe nausea, PTSD, autism spectrum disorder, drug abuse, insomnia, or any other chronic or persistent medical symptom.

Novel Cannabinoids and Cannabinoid Acids and Their Derivatives
20210238157 · 2021-08-05 ·

The present invention relates to novel cannabinoids 1 and 2, synthesized from simple starting materials using a cascade sequence of allylic rearrangement, aromatization and, for 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 are obtained containing very low levels of isomeric cannabinoids such as the undesirable Δ8-tetrahydrocannabinol. The 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 oil. Novel compounds of the formulas 3, 4, 5 and 6, as intermediates for the synthesis of the cannabinoids of the formulas 1 and 2 are also disclosed.
