The naturally occurring dibenzofuran cannabifuran ( has been synthesized from 2,3-dimethyoxy-p-toluic acid and 2-bromoolivetol dimethyl ether. In the key step, the aryl-aryl bond has been formed via a methoxy displacement in the aryloxazoline (). The final furan ring closure in () to () was accomplished by the HI/Ac2O reagent.
