Silicon-29 NMR Spectroscopy in Carbohydrate Chemistry: Galactose Derivatives

29Si NMR spectra of the O-trimethylsilyl (OTMS) derivatives of various methyl α- and β-D-galactopyranosides have been recorded.The effect of changes in the anomeric configuration provides a means of assigning the resonance of the 2-OTMS substituent.Whereas the signal of the OTMS group attached at the 6-position can be assigned readily, those of the OTMS group at the 3- or 4-position cannot be assigned unequivocally.

Ectyoceramide, the first natural hexofuranosylceramide from the marine sponge Ectyoplasia ferox

Ectyoceramide (1a), a unique monoglycosylceramide with a galactose in the furanose form, was isolated from Ectyoplasia ferox, and its structure was determined by NMR spectroscopy, multiple tandem mass spectrometry, and chemical degradation. Ectyoceramide is the first example of a monohexofuranosylceramide and, more generally, the first natural glycosphingolipid with its first sugar in the furanose form.

A convenient method for the cleavage of the D-mannosyl-L-gulose disaccharide from bleomycin-A2.

In order to elucidate the biological role of the sugar residue of the antitumor drug bleomycin, this was deglycosylated by beta-elimination under mild alkaline conditions, and by solvolysis with hydrogen fluoride. The latter procedure proved to be better because it led to the complete deglycosylation without modification of the peptide, thus allowing further biological investigations of this component.
