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.
