Stereocontrolled syntheses of a neutral glycosphingolipid found from a marine sponge Spheciospongia vesparia and its analogue have been accomplished. Disaccharide glycosphingolipids, β-D-Arap-(16)-β-D-Glcp-(11)-Cer (1) and α-D-Arap-(16)-β-D-Glcp-(11)-Cer (2), were synthesized from suitable monosaccharide donors and an acceptor by stepwise synthesis.
