method for decarboxylating a carboxylated phytocannabinoid compound of Formula I to form a phytocannabinoid compound of Formula II: Formula I Formula II wherein: R1 is selected from the group consisting of: substituted or unsubstituted C1-C5 alkyl; R2 is selected from the group consisting of: OH or O, and R3 is selected from the group consisting of: a substituted or unsubstituted cyclohexene, a substituted or unsubstituted C2-C8 alkene, or a substituted or unsubstituted C2-C8 dialkene; or R2 is O, and R2 and R3 together form a ring structure in which R2 is an internal ring atom; wherein the method includes heating a reaction mixture comprising the carboxylated phytocannabinoid compound and a polar aprotic solvent in the presence of a LiCl for a time sufficient to decarboxylate at least a portion of the carboxylated phytocannabinoid compounds and form the phytocannabinoid compound.
将化学方程式中的羧基化植物大麻化合物(Formula I)脱羧成形成另一种植物大麻化合物(Formula II)的方法:Formula I Formula II 其中:R1选自以下组合:取代或未取代的C1-C5烷基;R2选自以下组合:OH或O;R3选自以下组合:取代或未取代的环己烯,取代或未取代的C2-C8烯烃,或取代或未取代的C2-C8二烯烃;或者R2为O,且R2和R3共同形成一个环结构,其中R2是内环原子;该方法包括在存在LiCl的情况下,加热含有羧基化植物大麻化合物和极性非质子溶剂的反应混合物,以足够时间脱羧至少部分羧化植物大麻化合物并形成植物大麻化合物。
