Provided is a method for preparing synthetic cannabidiol, including hydrolysis-decarboxylation of a compound represented by formula (II) in a solvent-free state under atmospheric pressure. The method further includes preparation of the compound represented by formula (II). The method provides a safe, economical, environmentally friendly and scalable method for synthetic preparation of cannabidiol.
Disclosed is a method for preparing cannabidiol and analogues thereof; the method is implemented by means of reacting a resorcinol derivative with menthyl-2,8-dien-1-ol or a derivative thereof. The method of the present invention has advantages of such as high chemical reaction selectivity and simple operation.
