hyl)-1,3-butadiene, have been synthesized and their diene-transmissive Diels-Alder cycloadditions are investigated. The initial Diels-Alder reaction selectively occurs not across the diene part substituted with the alkoxyl moiety but the monosubstituted diene. Some cross types of diene-transmissive Diels-Alder reaction are demonstrated using the triene equivalent and two different dienophiles.
