1',1'-Cyclopropyl side chain substituents enhance the affinities of Delta(8)-tetrahydrocannabinol and respective cannabidiol analogues for the CB1 and CB2 cannabinoid receptors. The results support the hypothesis for a subsite within CB1 and CB2 binding domain at the level of the benzylic side chain carbon in the tetrahydrocannabinol and cannabidiol series. Efficient procedures for the synthesis of 1',1'-cyclopropyl analogues are described. (C) 2002 Elsevier Science Ltd. All rights reserved.

A regioselective Heck reaction of aliphaticolefins and aryl bromides is realized at internal carbons of olefins. Methanol solvent promoted halide ionization from neutral arylpalladium halide complexes via hydrogen bonding, so as to create cationic aryl-Pd species for regioselective olefin insertion.
