英文摘要: Abstract(#br)The preparation and NMR analysis of 2,3-di- O -benzyl d -ribose and 2,3-di- O - d -xylose are described. In DMSO- d 6 the sugars adopt a conformation in which the hydroxyl groups are in an equatorial position. In CDCl 3 and CD 2 Cl 2 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.
