Rac-12,14-Dicyclo-propyl-5,8,13,18,21-penta-oxapenta-cyclo-[13.8.0.0.0.0]tricosa-1(15),2(11),3,9(10),16,22(23)-hexa-ene.

ABSTRACT: The mol-ecule of the title compound, C(24)H(24)O(5), has crystallographic twofold symmetry, with the central O atom lying on the rotation axis. The dihedral angle between the best planes of the benzene rings fused to the oxepine fragment is 38.5?(1)°. The dioxine ring adopts a twist form with the ethyl-ene group C atoms deviating by 0.472?(5) and -0.248?(6)?Å from the plane defined by the remaining ring atoms.
