title: {(3aR,5S,6R,6aR)-5-[(R)-1,2-Di-hydroxy-eth-yl]-2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxol-6-yl}methyl methane-sulfonate.
abstract: In the title compound, C11H20O8S, the furan-ose ring has a pseudorotation phase angle equal to 31.3° and assumes a (3) T 4 conformation, with deviations of 0.297 (4) and -0.152 (4) Å for the corresponding C atoms. The dioxolane ring adopts an envelope conformation. One of the O atoms is at the flap and deviates from the least-squares plane formed by the other four ring atoms by 0.405 (2) Å. The dihedral angle between the planar fragments of the rings is 63.53 (8)°. In the crystal, mol-ecules are associated into sheets perpendiculer to the b axis by means of O-H⋯O hydrogen bonds. A few weak C-H⋯O inter-actions are also observed.
