Diels-Alder Reactions Catalyzed by Zeolites

Abstract
Various Zeolite catalysed Diels-Alder reactions of cyclopentadiene, cyclohexadiene and furan with less reactive dienophiles were studied. Exclusive endoselectivity was obtained with Ce-Y zeolite + anhydrous ZnBr2 for cyclopentadiene as well as cyclohexadiene Diels-Alder reactions.
