  Synthesis of novel types of divalent saccharide structures by a ketene acetal Claisen rearrangement

  摘要：

  A simple allyl uronate was rearranged to give the branched product, which in turn could be transformed into a spiroannellated bicyclic compound. More complex allyl uronates of D-and L-arabinose were rearranged to give novel methylene-bridged dimeric saccharide structures. (C) 2004 Elsevier Ltd. All rights reserved.
