Av. Nikolaev et al., PARASITE GLYCOCONJUGATES .4. CHEMICAL SYNTHESIS OF DISACCHARIDE AND PHOSPHORYLATED OLIGOSACCHARIDE FRAGMENTS OF LEISHMANIA-DONOVANI ANTIGENIC LIPOPHOSPHOGLYCAN, Journal of the Chemical Society. Perkin transactions. I, (16), 1995, pp. 1977-1987
The disaccharide 1, tetraglycosyl monophosphate 2, hexaglycosyl diphos
phate 3 and octaglycosyl triphosphate 4, which are fragments of the ph
osphoglycan portion of Leishmania donovani lipophosphoglycan, have bee
n synthesized. Elongation of the chain was performed using the suitabl
y protected glycobiosyl hydrogenphosphonate derivatives 5 and 6 for th
e successive introduction of glycobiosyl phosphate units.
