  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.
