Syntheses of various symmetrical naphthalenophanes and anthracenophanes via a Diels-Alder reaction between syn-[2.2](5,8)phthalazinophane derivatives and some selected dienophiles as well as the synthesis of other symmetrical heterophanes.
The syntheses of various classes of unreported naphthalenophanes, anthracenophanes and heterophanes are herein reported. The key to their successful preparation depends on the synthesis of syn-4,7,14,17-tetra(phenyl and chloro)-[2.2](5,8)phthalazinophanes as well as syn-4,5,6,7,14,15,16,17-octahydro[2.2](5,8)phthalazinophane- 4,7,14,17-tetraone and 4,5,12,13-tetrakis(methoxycarbonyl)-[2.2]paracyclophane.
