Several 2-thioglycosides were prepared. Glycosylation of 2-thioxo-thieno [2, 3-d]- pyrimidines 5a, b with 1-bromo-2, 3, 5-tri-O-acetyl-α-d-arabinofuranosyle 7, 2, 3, 4, 6-tetra-O- acetyl-α-d-glucopyranosyl and galacto-pyranosyl bromide 8a, b gave the protected β-d- nuclosides 10a, b and 13a–d in high yields, which were transformed to deacetylated derivatives 14a, b and 15a–d. The structures of the compounds were elucidated by ...
