construction of polyoxygenated dibenzo[b,d]furan frameworks from the union of substituted phenols/naphthols and o-benzoquinones via a Michael-oxidation-oxa-Michael cascade is reported. The power of this transformation is demonstrated in the generation of a library of highlysubstituted dibenzofurans, featuring specifically substituted molecules containing broad ranges of functionality. The utility of this
