  Synthesis and Selectin‐Blocking Activity of a Novel Analog of Sulfatide: 3‐C‐Carboxymethylgalactosyl Lipid

  摘要：

  The 3-C-carboxymethylgalactose derivative carrying the 2-(tetradecyl)hexadecyl residue, which was designed as a novel analog of sulfatide, was synthesized. A key intermediate, 3-C-carboxymethylgalactose, was prepared from the suitably protected galactose by Swern oxidation and Wittig-Horner carboxymethylenation, followed by stereoselective reduction of the double bond. The compound obtained showed much more potent activity as a selectin blocker than the 3-O-sulfogalactose derivative with 2-(tetradecyl)hexadecyl residue.
