syn-dimethanotetrahydroanthracene, -tetracene, and -pentacene derivatives 8a–d, 9a–d, and syn-25 are described. Highly stereoselective, pressure-induced Diels-Alder reactions of the bis-dienophiles 8a and/or 9a with the bis-diene 7 lead to the sterically rigid macrocycles 1a, 2a, and 3a/3b, which have well defined cavities of different sizes.
