Abstract

Under microwave irradiation (MWI), 4??phenyl??5??substituted??4H??1, 2, 4??triazole??3??thiol derivatives 7 and 8 were synthesized in a good yield by intramolecular cyclization of the aroyl phenyl thiosemicarbazides 5 and 6. The respective triazolylglycosides (Str??glycosides) 12–17 were obtained by reaction of triazoles 7 and 8 with glycosyl halides 9–11 in dry acetone in the presence of potassium carbonate as base under both conventional and ...
