Complete analysis of the1H- and13C-NMR spectra of four blood-group A active oligosaccharides

The fully assigned¹H and¹³C-NMR spectra of four group A oligosaccharides by use of multiple-relayed, coherence-transfer chemical-shift-correlated spectroscopy (multiple-RELAY-COSY) and¹H-/¹³C-correlation spectroscopy are reported. These analyses were performed on the following compounds: $$\begin{array}{*{20}c} {III - A;GalNAc\alpha 1 - 3[Fuc\alpha 1 - 2]Gal:} \\ {VI - A;GalNAc\alpha 1 - 3[Fuc\alpha 1 - 2]Gal\beta 1 - 3[Fuc\alpha 1 - 4]GlcNAc\beta 1 - 3Gal:} \\ {VII - A - 1;GalNAc\alpha 1 - 3[Fuc\alpha 1 - 2]Gal\beta 1 - 3[Fuc\alpha 1 - 4]GlcNAc\beta 1 - 3Gal\beta 1 - 1Glycerol:} \\ {VII - A - 2;GalNAc\alpha 1 - 3[Fuc\alpha 1 - 2]Gal\beta 1 - 3[Fuc\alpha 1 - 4]GlcNAc\beta 1 - 4Glc.} \\ \end{array}$$
