In the biologically active title compound, C(26)H(26)O(5), the pyran ring of the chromene unit adopts a half-chair conformation. The C=C double bond of the propenone unit exhibits a trans conformation and the carbonyl group is syn conformation to the double bond. The dihedral angle between the benze...

Descripción
Sumario:In the biologically active title compound, C(26)H(26)O(5), the pyran ring of the chromene unit adopts a half-chair conformation. The C=C double bond of the propenone unit exhibits a trans conformation and the carbonyl group is syn conformation to the double bond. The dihedral angle between the benzene ring and the benzopyran­one moiety is 31.54 (4)°. The mol­ecular structure is stabilized by an intra­molecular C=O⋯H—O hydrogen bond.
