S. Mataka et al., AROMATIC RING-SYSTEM CONTROLS PI-FACIAL SELECTIVITY IN DIELS-ALDER REACTIONS OF [3.3]ORTHOANTHRACENOPHANES, Tetrahedron letters, 36(34), 1995, pp. 6105-6108
The Diels-Alder reaction of layered [3.3]orthoanthracenophanes with el
ectron-poor dienophiles is studied. OF special interest is the anthrac
enonaphthophane, which was found to add naphthoquinone, maleic anhydri
de and maleimide favorably from the inside face and N-phenyltriazolind
ione and dimethyl azodicarboxylate to the outside.
