Descripción
Sumario:The title compound, C(45)H(34)O(4), is the product of a tandem ‘pincer’ Diels–Alder reaction consisting of two consecutive [4 + 2] cyclo­additions between two 2-benzofuran units and ethyl propiolate. The mol­ecule comprises a fused hexa­cyclic system containing four five-membered rings, which are in the usual envelope conformation, and two six-membered rings. In addition, four phenyl rings are attached to the hexa­cyclic system. The packing is stabilized by C—H⋯π inter­actions.
