Abstract

In the title compound, $C_{26}H_{30}O_5$, both the double bonds exist in an E configuration. The aryl rings are not coplanar with the adjacent olefinic groups owing to non-bonded interactions between the ortho H atoms of the aryl rings and the equatorial H atoms at the 3- and 5-positions of the cyclohexyl ring; the dihedral angles between the aryl rings and the olefinic groups are 33.7 (3) and $48.6 (4)^o$. The cyclohexanone ring adopts an envelope conformation and the crystal structure is stabilized by $C—H...O$ hydrogen bonds.
