An unusual Bronsted acid catalyzed benzofuran ring opening and furan ring closure sequence for the formation of tri- and tetrasubstituted furans is presented. Benzofuranyl carbinols and 1,3-dicarbonyls in the presence of a catalytic amount of an acid generated functionalized, polysubstituted furans in good to excellent yields via an unusual benzofuran ring opening and furan recyclization process. This reaction is found to be general even on furyl carbinols; however, it generates the rearranged polysubstituted furans in moderate yields.

A range of polysubstituted furans were synthesized from furan derivatives involving copper-catalyzed ring opening of the furan ring. This synthetic method possesses the advantages of readily available starting materials, mild reaction conditions, and shor
