3,5-Di-O-benzoyl-1,2-O-isopropylidene-α-d-ribo-hexos-3-ulo-1,4:3,6-difuranose

The title compound, C23H22O8, is a binary benzoyl ester whose nucleus consists of a fused system made up of a methylenedioxy ring and two tetrahydrofuran rings. One of the benzoyl ester groups is attached at the junction of the two tetrahydrofuran rings. The other is attached to the outer tetrafuran ring. Both the benzoyl ester groups are in an axial conformation with respect to the outer tetrhydrofuran ring. In the crystal, molecules are linked by two weak C—H...O hydrogen bonds, forming a chain running parallel to the a axis.
