Abstract: The title compound, C₈H₁₂O₄, is formed as a by-product in the preparation of the protected sugar 2,3-O-isopropylidene--D-ribose under acid-catalysed conditions (H₂SO₄/acetone) from D-ribose [Fleetwood & Hughes (1999). Carbohydr. Res. 317, 204-209]. The absolute configuration was assigned on the basis of the known D-ribose configuration.
