  The Total Synthesis of Immunostimulant α-Galactosylceramides from Naturally Configured α-Galactoside Raffinose

  摘要：

  The total synthesis of absolute anomeric confirmation alpha-galactosylceramide analogues from raffinose is described. Using the naturally occurring alpha-galactoside raffinose as the starting material, the easily maneuverable protocol without glycosylation reactions ensured the critical alpha-linkage in the product and simplified the synthetic procedures. The immunostimulatory activities of the new alpha-galactosylceramides were validated by both in vitro and in vivo NKT cell stimulation assays.

• Highly Efficient and Mild Method for Regioselective De-<i>O</i>-benzylation of Saccharides by Co₂(CO)₈-Et₃SiH−CO Reagent System

  日期：2010.2.5

  A highly efficient and mild method for the de-O-benzylation of protected saccharides was developed by transforming terminal benzyl ethers into silyl ethers using Co-2(CO)(8)-Et3SiH under 1 atm of CO. The method was successfully used for the de-O-benzylation of perbenzylated monosaccharides with various anomeric protecting groups, as well as natural disaccharides and trisaccharides such as sucrose, raffinose, and melezitose in good yields (>80%).

  Several partially benzylated mono-, di-, and trisaccharides having an anomeric hydroxyl group were successfully prepared by selective cleavage of the beta-fructofuranosidic linkage in fully benzylated sucrose and sucrose-related oligosaccharides derived from lactosucrose, raffinose, melezitose, stachyose, and nystose under acidic conditions using 1:10 75% aqueous sulfuric acid-dioxane at room temperature
