  Stereoselective Synthesis of a C-Linked Neuraminic Acid Disaccharide: Potential Building Block for the Synthesis of C-Analogues of Polysialic acids

  摘要：

  C-Linked neuraminic acid disaccharide was synthesized in a diastereoselective manner from a sulfone donor and aldehyde acceptor, which was protected as a propargyl ether, through a samarium-mediated coupling reaction. The resulting disaccharide has acetal and phenyl sulfide functional C groups that can be easily converted into aldehyde and phenyl sulfone groups by photolysis and oxidation reactions to serve as disaccharide acceptor and donor, respectively.
