Disaccharide mimetics of a heparin sequence that binds to fibroblast growth factors were prepared by coupling a D-galactose donor with a methyl beta-D-gluco- or xylopyranoside acceptor. When fully sulfated, the glucose or xylose moieties exist in solution in equilibrium between the (4)C1 and (1)C4 conformers, as confirmed by 1H NMR spectroscopy, thus mimicking the conformationallyflexible L-iduronic
