  2,4-Diazido-2,4,6-trideoxy-l-hexopyranoses as valuable building units in the synthesis of natural products

  摘要：

  Synthesis of five L-enantiomers of 2,4-diazido-2,4,6-trideoxy-pyranoses has been accomplished. These sugars were prepared via the regioselective protection of hydroxyl groups in L-rhamnoside and L-fucoside, followed by triflation and subsequent S(N)2 substitution with azido nucleophiles.
