Syntheses of α-, β-monoglycosylceramides and four diastereomers of an α-galactosylceramide

To examine antitumor activities of monoglycosylceramide, we synthesized α-, β-galactosylceramides and α-, β-glucosylceramides which have the same ceramide portion, and four kinds of diastereomers of the ceramide portion in an α-galactosylceramide.
