(E)-1-(4-Chlorophenyl)-3-[4-(2,3,4,6-tetra-O-acetyl-β-d-allopyranosyloxy)phenyl]prop-2-en-1-one

The asymmetric unit of the title compound, C29H29ClO11, contains two independent molecules of similar geometry, both adopting an E conformation about the C=C double bond. The dihedral angles formed by benzene rings are 10.73 (16) and 13.79 (18)°. The pyranoside rings adopt a chair conformation. Intramolecular C—H...O close contacts occur. The crystal packing is stabilized by intermolecular C—H...O hydrogen bonds
