Abstract
A method is described for the production of 6,12-dihydro-6-hydroxy-cannabidiol which is obtained by the reaction of olivetol and cis-p-menth-2-ene-1,8,-diol and the reaction thereof to yield trans-delta-9-tetrahydrocannabinol.

A method of producing 6,12-dihydrohydroxy-cannabidiol of the formula (I) ##STR2## wherein an equimolar amount of olivetol of the formula (II) ##STR3## is reacted with cis-p-menth-2-ene-1,8-diol of the formula (III) ##STR4## in an organic solvent in the presence of a Lewis acid catalyst.
A method for producing trans-delta-9-tetrahydrocannabidiol of the formula (IV) ##STR5## wherein a ring condensation is performed on 6,12-dihydro-6-hydroxy-cannabidiol of the formula (I) ##STR6## in a solvent selected from the group consisting essentially of hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons and in the presence of a Lewis acid as a catalyst.
