Abstract
The thermal and catalyzed Diels-Alder reactions of (+)-apoverbenone (1) with isoprene, 2, 3-dimethyl-1,3-butadiene, (E)-piperylene, (E)-1-methoxy-1,3-butadiene and cyclopentadiene are described; structural analysis by 1H and 13C-NMR spectroscopy is reported, and the syn-anti and endo-exo diastereoselectivity of the reactions is discussed.
