Parasite glycoconjugates. Part 9.1 Synthesis of dec-9-enyl β-D-galactopyranosyl-(1→4)-α-D-mannopyranosyl phosphate and its epimers at the D-galactose moiety, substrate analogues for the elongating α-D-mannopyranosylphosphate transferase in the Leishmania

Abstract

A set of phosphodisaccharides, substrate analogues, which will be used to study the acceptor substrate specificity of the Leishmania biosynthetic enzymes, have been synthesized using the trichloroacetimidate method for the glycosylation reactions, S_N2 nucleophilic displacement of triflic esters for epimerization and the glycosyl hydrogenphosphonate method for phosphorylation.
