The iron-catalyzed six-membered ring carbocyclizations of 5-oxa-2,8,10-undecatriene derivatives proceed with high regio-and stereoselectivity to yield trans-3,4-disubstituted tetrahydropyrans. Substrates containing an alkyl substituent at the 4-or the 7-position of the starting triene ether cyclize
