Abstract
In the central fused ring system of the title compound, C51H42O5, all of the five-membered rings are in an envelope conformation. The dihedral angle between the two benzene rings in the fused ring system is 74.66 (7)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming a layer parallel to the ab plane. Each mol-ecule acts as a double donor as well as a double acceptor of the C-H⋯π inter-actions. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H (61.4%) and C⋯H/H⋯C (25.3%) contacts.

Summary
The hexadehydro-Diels–Alder reaction, by which benzyne intermediates (Niu et al, 2013) as well as highly functionalized benzenoid products (Karmakar et al, 2013) are prepared, has played a very significant role in the field of organic synthesis. Zhang et al (2015) observed that benzyne intermediates can be captured by five-membered heterocyclic compounds, such as furans, pyrroles and thiophenes.
