3-[(1,3-Benzodioxol-6-yl)methylene]-4-(pentan-3-ylidene)tetrahydrofuran-2,5-dione.

In the structure of the title compound, C17H16O5, the dihydrofuran ring adopts an envelope conformation while the methylenedioxyphenyl ring system is essentially planar. The vinyl group is inclined to the dihydrofuran ring by 30.22 (12)°. The dihedral angle between the atoms defining the planar part of the dihydrofuran ring and the aryl ring is 19.12 (8)° [ABSTRACT FROM AUTHOR]
