By the nucleophilic substitution reaction of 6-O-tosyl-l,2:3,4-di-O- isopropylidene-a-Z)-galactopyranose (3) with some substituted 1, 2,4- triazole-3-thiols (4a ~ 4c) or 1, 2, 3,4-tetrazole-5-thiols (5a~5f), nine 6-S-(substituted triazolyl or tetrazolyl)-l,2 : 3,4-di-O- isopropylidene-a-D)-galactopyranoses (6a ~ 6i) were prepared in high yields. Their structures and configurations were analyzed and established by elemental analysis, IR, NMR, MS spectra.
