(2R*,4R*,7S*,10R*,12R*)-3,11,13,15-Tetra-oxa-penta-cyclo-[5.5.3.0(1,7).0(2,4).0(10,12)]penta-deca-5,8-dien-14-one.

ABSTRACT: The title compound, C11H8O5, features a 'skipped' diene, an anti-bis-(epoxide) and a cyclic carbonate, all embedded in a densely functionalized [4.4.3]propellane scaffold. The crystal packing of this diepoxide is effected primarily by C-H⋯O hydrogen bonds, which link the mol-ecules into tapes along the b axis. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of C⋯O contacts [3.183 (4) Å] between the C(δ+)=O(δ-) dipoles of neighbouring carbonate moieties.
