Dibenzopyran

Dibenzopyrans are a chemical class of organic compounds consisting of a tricyclic ring system in which two rings flank a central oxygen-containing pyran ring. This ring system underlies the classical phytocannabinoids. Members act at the cannabinoid receptors, producing effects that range from intoxication to more subtle modulation depending on the specific compound. The tricyclic dibenzopyran framework is the defining structural feature of the class.
