Abstract: The present disclosure relates to the preparation of a cannabidiol compound or a derivative thereof. The cannabidiol compound or derivatives thereof can be prepared by an acid-catalyzed reaction of a suitably selected and substituted di-halo-olivetol or derivative thereof with a suitably selected and substituted cyclic alkene to produce a dihalo-cannabidiol compound or derivative thereof. The dihalo-cannabidiol compound or derivative thereof can be produced in high yield, high stereospecificity, or both. It can then be converted under reducing conditions to a cannabidiol compound or derivatives thereof.

Abstract: The present disclosure relates to a cannabidiol compound and compositions thereof and processes for preparing the compound and compositions. The processes include an acid-catalyzed reaction of a suitably selected and substituted di-bromo-olivetol or derivative thereof with a suitably selected and substituted cyclic alkene to produce a dibromo-cannabidiol compound or derivative thereof. The dibromo-cannabidiol compound or derivative thereof can be produced in high yield, high stereospecificity, or both. It can then be converted under reducing conditions to a cannabidiol compound or derivatives thereof.

Abstract: The present disclosure relates to N-demethylation of a compound containing a tertiary N-methylamine, including for example a morphinan alkaloid, in a continuous flow system. In particular, the present disclosure relates to N-demethylation of oxymorphone-3,14-diacetate or 14-hydroxymorphinone-3,14-diacetate using highly active catalytic palladium (0) in a continuous flow system under elevated temperature and pressure condition. The methodology can be utilized towards the synthesis of noroxymorphone via aerobic palladium-catalyzed continuous flow N-demethylation.
