Khimiya Prirodnykh Soedinenii (3): 283-285



An alternative synthesis of methyl(methyl-2,3,4-tri-O-methyl-.alpha.-D-galactopyranoside)uronate from 6-O-benzyl-.alpha.-D-galactopyranoside was accomplished. The scheme involved exhaustive methylation, hydrogenolysis of the benzyl group, oxidation and esterification. 2,3-, 2,4-, 3,4-di-O- and 2,3,4-tri-O-methyl esters of methyl(methyl-.alpha.-D-galactopyranoside)uronate were prepared.
