Cc. Lin et al., Synthesis of beta-D-glucopyranosyl(1 -> 3)-1-thiol-beta-glucosamine disaccharide derivative as building block for the synthesis of hyaluronic acid, J CHIN CHEM, 47(4B), 2000, pp. 921-928
A practical synthetic method for the title disaccharide 2 is described. Gly
cosylation using thioglycoside as acceptor and glycosyl imidate as donor wa
s performed with trimethylsilyltriflate as the promoter.
