title: Novel 1',1'-chain substituted Delta(8)-tetrahydrocannabinols.
abstract: 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.
