Abstract
In the title compound, C15H16O6, obtained from the acyl-ation reaction between 2,3-O-iso-propyl-idene-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, mol-ecules of the acyl-ated sugar are linked by very weak inter-molecular C-H⋯O inter-actions, forming a three-dimensional network.
