The synthesis of methyl 3-O-(beta-D-fucopyranosyl)-beta-D-Quinovopyranoside and its 3'-O-, 2,3'-Di-O-, and 2', 3'-Di-O-methyl derivatives
No full textMethyl 3-O-(β-D-fucopyranosyl)-β-D-Quinovopyranoside and its 3'-O-, 2,3'-Di-O-, and 2', 3'-Di-O-methyl derivatives were obtained by the regioselective Helferich glycosylation of methyl-2-O-benzyl-β-D-quinovopyranoside with the 2,3,4-tri-O-benzyl-α-Dfucopyranosyl bromide followed by the methylation with diazomethane or methyl iodide
