摘要

Two isomeric partially acetylated galactocerebrosides, ?-D-galactopyranosyl (2,3,4-tri-O-acetyl)- and ?-Dgalactopyranosyl (2,4,6-tri-O-acetyl)-1’(3’-O-acetyl)ceramide, were prepared from galactocerebroside and sulfatide, respectively. Their galactofuranosylation produced ?-D-galactofuranosyl-6- and ?-D-galactofuranosyl-3-?-Dgalactopyranosyl- 1’ceramide, as demonstrated by 1H and 13C NMR spectra as well as by chemical means.
