Crystal structure of 4,6-dimethyl-2-[(2,3,4,6-tetra-O-acetyl-β-d-galacto-pyranos-yl)sulfan-yl]pyrimidine.

ABSTRACT: In the title com-pound, C₂₀H₂₆N₂O₉S, the S atom is attached equatorially to the sugar ring. The C-S bond lengths are unequal, with S-C_s = 1.8018 (13) Å and S-C_p = 1.7662 (13) Å (s = sugar and p = pyrimid-yl). In the crystal, a system of three weak hydrogen bonds, sharing an oxygen acceptor, links the mol-ecules to form chains propagating parallel to the b-axis direction.

Project description:In the title compound, C(16)H(24)N(4)O(9)S(2)·H(2)O, the hexopyranosyl ring adopts a chair conformation ((4)C(1)), and the five substituents are in equatorial positions. In the crystal structure, extensive O-H⋯O, N-H⋯S and N-H⋯O hydrogen bonding leads to the formation of a three-dimensional network.

2,3,4,6-Tetra-O-acetyl-β-d-galacto-pyranosyl 2,3,4,6-tetra-O-acetyl-β-d-glucopyranosyl disulfide tetra-hydro-furan solvate.

Project description:The asymmetric unit of title compound, C(28)H(38)O(18)S(2)·C(4)H(8)O, comprises one disulfide-bridged sugar molecule and one solvent molecule. No significant differences in structural parameters are found between the present structure and the previously determined unsolvated form [Brito, López-Rodríguez, Bényei & Szilagyi (2006 ▶). Carbohydr. Res.341, 2967-2972]. The compounds are characterized by a compact structure with spatial proximity of the two pyranosyl rings. One of the carbonyl atoms is disordered over two sites [site occupancy = 0.69 (7) for major component] and the displacement parameters for the THF species are unsually large.

Project description:The title compound, C(18)H(26)O(11), was synthesized by a condensation reaction of 2,3,4,6-tetra-O-acetyl-α-d-galactopyranosyl bromide and butyric acid. The acet-oxy-methyl and butyrate groups are located on the same side of the pyran ring, showing the β configuration for the d-glycosyl ester; the butyl group adopts an extend conformation, the C-C-C-C torsion angle being 179.1 (7)°. In the crystal, the mol-ecules are linked by weak C-H⋯O hydrogen bonds.
