The invention involves condensation of various derivatives of cyclic alkene alcohols of Formula (II) or Formula (III) where, R1 is alkyl, aryl, alkyl aryl or heterocyclic carbamoyl. R2 is either R1 as mentioned earlier or an acyl group, -C(=O)-R3 where, R3 is selected from a group comprising (subst)C1-C12 alkyl, (subst)aryl, alkyl aryl with olivetol to get (-)-trans-∆9-tetrahydrocannabinol (also known as Dronabinol, Formula (I)). The process disclosed provides high purity of dronabinol at crude stage making it easy for purification.
该发明涉及将环烯醇衍生物的各种衍生物进行凝结,其中环烯醇的化学式为(II)或(III),其中,R1为烷基、芳基、烷基芳基或杂环羰胺。R2可以是前述的R1,也可以是酰基、-C(=O)-R3,其中,R3选自包括(subst)C1-C12烷基、(subst)芳基、烷基芳基的一组化合物,与橄榄酚发生反应,得到(-)-反式-∆9-四氢大麻酚(也称为Dronabinol,化学式(I))。所披露的方法在原料阶段提供了高纯度的Dronabinol,使其易于纯化。
