Synthesis and NMR assignments of galactosylgloboside and its β-d-GalNAc-(1→4)-α-D-Gal-linked positional isomer in a conjugatable form

Two pentasaccharides suitable for conjugation, namely 3-aminopropyl glactosylgloboside and its β-D-GalNAc-(1→4)-α-D-Gal-linked positional isomer, were synthesized from 3(III),4(III)-di-O-unprotected globotrioside and the trichloroacetimidate of β-D-Gal-(1→3)-β-D-GalNPhth derivative. Glycosylation at both positions led to the formation of β-D-GalNPhth-(1→4)-α-D-Gal and β-D-GalNPhth-(1→3)-α-D-Gal-linked products in a ratio of 1:1 without selectivity. Complete NMR spectral assignments are also described. Copyright (C) 1999 Elsevier Science Ltd.
