title: 2,3-O-Isopropyl-idene-3-C-phenyl-erythrofuran-ose.
abstract: The title compound, C(13)H(16)O, comprises two fused five-membered rings. Each ring has an envelope conformation, with the ether O atom in the furan-ose ring, and the CMe(2) atom in the acetonide ring as the flap atoms. In the crystal, centrosymmetrically related mol-ecules associate via hydr-oxy-ether O-H⋯O hydrogen bonds and the resulting dimers are linked into a supra-molecular chain with a flattened topology via C-H⋯O(hydr-oxy) contacts, and aligned in the a-axis direction.
