Aluminum chloride catalyzed Diels-Alder reactions of a bicyclic dienone of the 2,5-cyclohexadienone type with 1,3-butadiene, isoprene, and (E)-piperylene are described. Structure analysis of the adducts by NMR spectroscopy is presented. The site selectivity and face diastereoselectivity of the reactions are discussed.
