{(3aR,5S,6R,6aR)-5-[(R)-1,2-Di­hydroxy­eth­yl]-2,2-di­methyl­tetra­hydro­furo[2,3-d][1,3]dioxol-6-yl}methyl methane­sulfonate

Abstract: In the title compound, C11H20O8S, the furan­ose ring has a pseudorotation phase angle equal to 31.3° and assumes a 3T4 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, mol­ecules are associated into sheets perpendiculer to the b axis by means of O-H...O hydrogen bonds. A few weak C-H...O inter­actions are also observed.
