Abstract

The title compound, C(7)H(10)O(6), was obtained from a regioselective enzyme-catalysed acyl-ation of d-ribono-1,4-lactone. The five-membered ring of the acyl-ated sugar shows an envelope conformation. In the crystal, the mol-ecules are linked by inter-molecular O-H⋯O hydrogen-bonds, forming a one-dimensional polymeric structure parallel to [010]. In addition, packing analysis shows stacking along the b axis.
