title: (2R,3aR,4S,7R,7aS,9R,10aR,11S,14R,14aS)-rel-3a,4,7,7a,10a,11,14,14a-Octa-hydro-4,14:7,11-diep-oxy-2,9-propanona-phtho[1,2-f:5,6-f']diisoindole-1,3,8,10-tetrone (9CI): a cyclo-phane derived from naphtho[1,2-c:5,6-c]difuran.
abstract: The title compound, C(25)H(18)N(2)O(6), is a naphthalenophane styled in the manner of Warrener's alicyclic cyclo-phanes or mol-ecular racks wherein a trimethyl-ene tether is perfectly staggered between the two N atoms such that the central methyl-ene H atoms point toward the naphthalene π-system. The dihedral angle between the mean planes of the two benzene rings is 7.61 (7)°.
