Abstract: On the basis of the known absolute configuration of D-galactose, the structural study of 3-deoxy-D-xylo-galactono-1,4-lactone, C₆H₁₀O₅ 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.
