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.
