摘要：
Ketone derived from diacetone-alpha-D-glucose is a suitable starting material for the synthesis of 3-C-linked glycohybrids containing 1,2,3-triazole moiety as an intersugar linkage. The pyranose tautomers of 3-deoxy-3-(1,2,3-1H-triazol-1-yl) glucose, 3-C-[(1,2,3-1H-triazol-1-yl) methyl] allose and 3-C-[(1,2,3-1H-triazol-1-yl) methyl] gulose moieties are released upon the acidic hydrolysis of the corresponding O-isopropylidene-protected furanosyl-type synthetic intermediates. Some of the title compounds show a rare property of activating beta-galactosidase from Escherichia coli.
