N-Glycosides of nitrogen heterocycles XIV. Synthesis of 2,6-bis[5-N-(b-D-glycopyranosylamino)-1,3,4-oxadiazol-2-yl]pyridine. Borkowski, Boguslaw; Wojtowicz, Mscislaw; Gmernicka-Haftek, Cecylia; Nowakowska, Zofia; Bogacka, Izabella (Dep. New Drugs, Inst. Drug Res. Control, Warsaw 00-725, Pol.). Acta Pol. Pharm., 39(1-3), 55-60 (Polish) 1982. CODEN: APPHAX.In this article, certain chemicals are used. One of their cas registry numbers is 80666-77-9 ISSN: 0001-6837. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Section cross-reference(s): 28 D-Glucopyranosyl- and D-galactopyranosylbis[(thiocarboxamido)carbazoyl]pyridines I (R = tetraacetyl-D-glucopyranosyl, tetraacetyl-D-galactopyransoyl) were cyclized by desulfuration with yellow HgO. Hydrolysis with aq. ammonia of the resultant oxadiazolylpyridines II (R as before) gave II (R = D-glucopyranosyl, D-galactopyranosyl). The NH groups of II were acylated on reacetylation with Ac2O in pyridine. Spectrometric studies confirmed the presence of the b-N-glycosidic linkage and 1C1 conformation of the sugar ring in the obtained compds. .
