The total synthesis of immunostimulant α-galactosylceramides from naturally configured α-galactoside raffinose.

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