A recently filed patent (Publication Number: US20240002320A1) outlines a method for preparing cannabigerol (CBG) or a CBG analog by reacting geraniol with a compound (I) of a specific structure. The method involves the use of a solvent, with options including chloroform, heptane, and diethyl ether, among others. The compound (I) and geraniol are to be present in a specific molar ratio, and an acid catalyst is utilized in a defined amount to facilitate the reaction. Additionally, the patent details variations in the alkyl group (R1) present in the compound (I) structure, offering flexibility in the process.

Furthermore, the patent extends the method to prepare a CBG analog by reacting geraniol with the same compound (I) structure but introduces different acid catalyst options such as camphorsulfonic acid and acidic alumina. The use of specific solvents and molar ratios between the compound (I) and geraniol are reiterated in this context as well. The patent also specifies the inclusion of an acid catalyst in a defined amount and highlights the importance of performing the reaction step with heating. These detailed claims provide a comprehensive guide for preparing CBG and its analog using specific reagents and conditions, offering potential applications in the pharmaceutical and cannabinoid industries.
