Controlling the Stereochemistry of the Ring Junction in Hexahydrodibenzofurans

The 8-hydroxy-1,2,3,4,4a,9b-hexahydrodibenzofuran-3-one formed during the acid-catalyzed rearrangement of 1,4,4a,8a-tetrahydro-1-methoxy-1,4-ethanonaphthalene-5,8-dione is, contrary to published reports, exclusively the cis isomer by X-ray crystallography
