The preparation and NMR analysis of 2,3-di-O-benzyl d-ribose and 2,3-di-O-d-xylose are described. In DMSO-d6 the sugars adopt a conformation in which the hydroxyl groups are in an equatorial position. In CDCl3 and CD2Cl2 the sugars adopts a conformation in which intramolecular hydrogen bonding plays an important role in determining the equilibrium composition. These findings were also confirmed by DFT studies and, in the solid phase, by X-ray single crystal diffraction.
