The Lewis acid catalyzed Diels-Alder reactions of 4-acetoxycyclopentenone 3 with both cyclic and acyclic dienes is described. Subsequent base induced elimination of the B-acetoxy group from the respective cycloadducts Ieaak to bi-and tricyclic erwnes in good yields. The x-facial diastereoselectivity
