Abstract

Two tricyclic dihydrobenzofuran cannabinoids, cannabielsoic acids A (4a) and B (5a) were isolated from hashish. Their structures were elucidated by chemical transformations and from spectral data. Cannabielsoic acid A was synthesized from cannabidiolic acid by an oxidative cyclization in the presence of air under irradiation, or with manganese dioxide.
