Abstract
In each independent molecule of the title compound, C28H26O4, the pyran rin g adopts a half-chair conformation and the tetrahydrobenzene ring is in a f lattened-boat conformation. The phenyl rings are orthogonal to each other; in one of the enantiomers, they form dihedral angles of 74.66(6) and 54.38( 6)degrees with the pyran ring, while in the other enantiomer, these angles are 76.42 (6) and 54.15(5)degrees.
