Synthesis and pharmacology of the isomeric methylheptyl-Delta(8)-tetrahydrocannabinols

The synthesis of the 3-heptyl, and the eleven isomeric 3-methylheptyl-Delta(8)-tetrahydrocannabinols (3-7, R and S methyl epimers, and 8) has been carried out. The synthetic approach entailed the synthesis of substituted resorcinols, which were subjected to acid catalyzed condensation with trans-para-menthadienol to provide the Delta(8)-THC analogue. The 1'-, 2'- and 3'-methylheptyl analogues (3-5) are considerably more potent than Delta(8)-THC. The 4'-, 5'- and 6'-methylheptyl isomers (6-8) are approximately equal in potency to Delta(8)-THC.
