1,4-Dialkoxy 1,3-dienes and bis(dienes)–stereocontrolled synthesis and reactivity

Abstract
γ-Aryloxy and -alkoxy α,β-unsaturated dimethyl acetals are direct precursors to (1Z, 3E)-1,4-dialkoxy 1,3-dienes and bis(dienes) which are fine partners in cycloaddition reactions with classical dienophiles.
