The glycosphingolipid neurosporaside (α-D-Glcp-(1→2)-β-D-Galp-(1→6)-β-D-Galp-(1→6)-β-D-Galp-(1→)-Cer) occurs in Neurospora crassa. We attempted to synthesize neurosporaside by block synthesis (route A) and linear synthesis (route B). Oligosaccharide derivatives were synthesized using trimethylsilyltrifluoromethanesulfonate and N-iodosuccinimide/trifluoromethane sulfonic acid as promoters. The target tetrasaccharide could not be attained via route A, but route B showed potential: glycosidic bonds (β-D-Galp-(1→6)-β-D-Galp-(1→6)-β-D-Galp) were formed stereoselectively, leading to the synthesis of glycosphingolipid 2.

Effective syntheses of galactose hepta-, octa-, nona-, and decasaccharides that exist in the rhizomes of Atractylodes lancea DC were achieved with 2,3,4,6-tetra-O-benzoyl-α-D-galactopyranosyl trichloroacetimidate (1), 4-methoxyphenyl 2,3,4-tri-O-benzoyl-β
