Disclosed is the trisaccharide .alpha.-D-Glcp-(1-2)-.alpha.-D-Glcp-(1-3)-.alpha.-D-Glcp and compounds related thereto as well as pharmaceutical compositions thereof.
The influence of C2 [OH F] substitution on the stereochemical course of chemicalglycosylation was interrogated in both D-glucose and its C4 epimer D-galactose. Molecularediting at C2 and configurational inversion at C4 were simultaneously investigated by variable-temperature glycosylation studies of both systems. Extrapolation of the differences in enthalpic (ΔΔHβα‡) and entropic (ΔΔSβα‡) contributions
