Abstract
1-Thio-β-D-glucopyranurono-6, 1-thiolactone was prepared by hydrolysis of methyl 2, 3, 4-tri-O-acetyl-1-thio-β-D-glucopyranuronate 1-ethylthionocarbonate which was prepared from methyl 2, 3, 4-tri-O-acetyl-1-bromo-1-deoxy-α-D-glucopyranuronate and potassium ethylxanthate. Methylation of this compound with diazomethane and subsequent acetylation afforded methyl (methyl 2, 3, 4-tri-O-acetyl-1-thio-β-D-glucopyranosid) uronate.
