摘要:
Five designed chiral glycosylated amino acids have been synthesized for the first time by coupling of 1,3,4,6-tetra-O-acetyl-β-D-glucosamine sulfate (2), previously prepared by direct acetylation of D-glucosamine hydrochloride with acetic anhydride, with chiral Fmoc-protected amino acids and DIC, HOBt, and DIEA under mild conditions. The structures of these new compounds were characterized by IR, 1H NMR, and 13C NMR spectroscopy and ESI MS.
