“Cannabisol (1), a unique dimer of Δ9-tetrahydrocannabinol (Δ9-THC) with a methylene bridge, was isolated from Cannabis sativa.
This is the first example of a C-bridged dimeric cannabinoid.
The structure of 1 was unambiguously deduced by HRESIMS, GCMS, and NMR spectroscopy.
A plausible biogenesis of 1 is described.”
