Abstract: Cannabinol (CBN) is a minor cannabinoid found in the cannabis plant and there is significant interest in exploring CBN for pharmaceutical applications. It is currently being investigated for treating glaucoma, sleep disorders and skin inflammations. Several synthetic approaches for CBN have been described in the prior art, however methods are still limited in scope because of the harsh reaction conditions, number of steps involved, low yields and extensive purifications that are generally required. The present disclosure relates to new cannabinol precursor compounds and processes to prepare cannabinol compounds. The disclosure also relates to the use of catalysts and catalytic processes for the preparation of cannabinol compounds from the cannabinol precursors.
Abstract: 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(trimethylsilyloxy)phenylromethanesulfonate. 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.
Abstract: The present disclosure relates to new cannabinoid derivatives and precursors and processes for their preparation. The disclosure also relates to pharmaceutical and analytical uses of the new cannabinoid derivatives.
Abstract: The present disclosure relates to new cannabinoid derivatives and precursors and catalytic asymmetric processes for their preparation. The disclosure also relates to pharmaceutical compositions and pharmaceutical and analytical uses of the new cannabinoid derivatives. For instance, the disclosure relates to the preparation of new precursors, and the use of such precursor compounds for the preparation of isotope labelled cannabinoid products using chiral and achiral catalysts and catalytic processes. The deuterium, carbon-13 and carbon-14 containing compounds can be prepared and purified prior to transformation to the desired individual deuterated cannabinoid products.
Abstract: The present disclosure relates to a new catalytic process for the production of methanol from carbon dioxide, comprising: (1) the conversion of carbon dioxide and hydrogen to formic acid or formate salts; (2) converting the formic acid or formate salts to diformate esters of diols; (3) hydrogenating the diformate esters to methanol and diols. The diols produced from the hydrogenation reaction can be recovered and re-used to prepare the diformate esters.
