An efficient and facile method for the synthesis of a broad series of benzofurans and naphthofurans is described. The direct intramolecular cyclodehydration of aryloxyketones in the presence of titanium tetrachloride affords the corresponding benzofurans and naphthofurans with good regioselectivity and yields.
Dimethyldioxirane epoxidation of benzofurans: Reversible thermal and photochemical valence isomerization between benzofuran epoxides, quinone methides, and benzoxetenes

Low-temperature oxidation of the four possible regioisomeric methoxy-substituted benzofurans 1 by dimethyldioxirane afforded the rather labile epoxides 2, which are in equilibrium with their equally labile quinone methides 3 through reversible valence iso
