Abstract :
In the title compound, C15H16O6, obtained from the acylation reaction between 2,3-O-isopropylidene-D-ribono-1,4-lactone and benzoyl chloride, the known absolute configuration for the lactone moiety of the ester substituent has been confirmed. The five-membered rings of the bicyclic lactone–dioxolane moiety both show envelope conformations and form a dihedral angle of 19.82 (7)° between the lactone ring and the benzene ring. In the crystal, molecules of the acylated sugar are linked by very weak intermolecular C—H⋯O interactions, forming a three-dimensional network.
