3,5-Di-O-benzoyl-1,2-O-isopropyl-idene-α-d-ribo-hexos-3-ulo-1,4:3,6-difuran-ose.

ABSTRACT: The title compound, C(23)H(22)O(8), is a binary benzoyl ester whose nucleus consists of a fused system made up of a methyl-enedi-oxy ring and two tetra-hydro-furan rings. One of the benzoyl ester groups is attached at the junction of the two tetra-hydro-furan rings. The other is attached to the outer tetra-furan ring. Both the benzoyl ester groups are in an axial conformation with respect to the outer tetrhydro-furan ring. In the crystal, mol-ecules are linked by two weak C-H⋯O hydrogen bonds, forming a chain running parallel to the a axis.
