On the basis of the known absolute configuration of d ‐galactose, the structural study of 3‐deoxy‐ d ‐ xylo ‐galactono‐1,4‐lactone, C 6 H 10 O 5 a valuable synthetic intermediate, allowed the unambiguous confirmation that the chiral centre at position 2 has the R configuration. This centre is formed during synthesis of the title compound from d ‐galactose under environmentally friendly conditions. Three symmetry‐independent intermolecular hydrogen bonds link the molecules into layers parallel to the ac plane.
