The title compound, C21H18O2, resulted from a Diels-Alder reaction. The chromanone moiety consists of one benzene ring fused with a six-membered heterocyclic ring, which adopts a half-chair conformation. In the bicyclo[2.2.1]heptene (norbornene) unit, the two five-membered rings are in envelope conformations, while the six-membered ring adopts a boat conformation. The dihedral angle between chromanone system and norbornene six-membered ring moiety is 54.5 (4)° and that between the norbornene six-memebered ring and the phenyl substituent is 68.0 (1)°.
