[GRAPHICS]An efficient method for the synthesis of trans-fused polycyclic ether ring systems including tetrahydropyrans and oxepanes, i.e., six-seven-six-, six-seven-seven-, and six-seven-seven-six-membered polycyclic ether ring systems, was developed on the basis of SmI2-induced reductive intramolecular cyclization.
