In the title compound, C(15)H(20)O(4)S, a dioxolane ring is fused to the pyran ring of the sugar which carries a thio-phenyl substituent on the anomeric C atom. The dioxolane ring adopts an envelope conformation and the pyran ring system a distorted (4)C(1) chair. The structure is stabilized by O-H⋯O hydrogen bonds, forming centrosymmetric dimers that generate an R(2) (2)(10) ring motif. Additi...

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 ...
