In the title compound, C(25)H(27)NO(5), each of the cyclo­hexenone rings adopts a half-chair conformation, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms. In the crystal, weak C—H⋯O hydrogen bo...

description In the title compound, C(25)H(27)NO(5), each of the cyclo­hexenone rings adopts a half-chair conformation, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms. In the crystal, weak C—H⋯O hydrogen bonds link mol­ecules into chains parallel to the c axis.
