  Stereoselective Synthesis of Dithymidine Phosphorothioates Using Xylose Derivatives as Chiral Auxiliaries

  摘要：

  1,2-O-Cyclopentylidene-5-deoxy-5-isopropylamino-alpha-D-xylofuranose 1 and its enantiomer 11 were used as chiral auxiliaries to form, respectively, Sp and Rp dithymidine phosphorothioates 9 and 10 in 98% diastereomeric excess, using phosphoramidite methodology and 2-bromo-4,5-dicyanoimidazole as catalyst. The stereochemistry of the coupling reaction is discussed.
