    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.

  • Synthesis of a Potent Antagonist of E-Selectin
    作者:Stephen Hanessian、Vincent Mascitti、Olivier Rogel
    DOI:10.1021/jo0110956
    日期:2002.5.1
    A synthesis of an antagonist of E-selectin previously reported by a group at Novartis Pharma in Basel is described. An important feature involves the formation of an ether linkage based on a Rh-II-catalyzed reaction. Stereocontrolled glycosylations rely on the anomeric activation of 2-pyridylthio carbonate as leaving group for the attachment of beta-D-galactopyranosyl and alpha-L-fucopyranosyl units on a common 1,5-anhydro D-glucitol scaffold.
