  Synthesis of Sugar Nucleotides by Application of Phosphoramidites

  摘要：

  A new method for the construction of pyrophosphates is reported based on the coupling of a sugar phosphate and a nucleoside phosphoramidite. The in situ formed phosphate-phosphite intermediate Was subsequently oxidized with tBuOOH. Three UDP-N-acetylglucosamine derivatives were prepared using this one-pot procedure in good yields.
