Methyl 3-O-α-d-mannopyranosyl β-d-glucopyranoside tetrahydrate
The title compound, C(13)H(24)O(11)·4H(2)O, forms extended hydrogen-bonded networks. These are present between disaccharides, but not as inter-residue hydrogen bonds, as well as to water mol-ecules that in addition form an inter-molecular chain of hydrogen bonds. The conformation of the disaccharide is described by the glycosidic torsion angles ϕ(H) = -34° and ψ(H) = -5°. Macroscopically, the d...
متن کاملMethyl 3-O-α-l-fucopyranosyl β-d-glucopyranoside tetrahydrate
The title compound, C(13)H(24)O(10)·4H(2)O, is the methyl glycoside of a disaccharide structural element present in the backbone of the capsular polysaccharide from Klebsiella K1, which contains only three sugars and a substituent in the polysaccharide repeating unit. The conformation of the title disaccharide is described by the glycosidic torsion angles ϕ(H) = 51.1 (1)° and ψ(H) = 25.8 (1)°. ...
متن کامل2-Acetamido-2-deoxy-3-O-β-d-galactopyranosyl-d-glucose dihydrate
In the title compound, C(14)H(25)NO(11)·2H(2)O, the primary hydroxyl group connected to the anomeric C atom of the N-acetyl-β-d-glucopyran-ose residue exhibits positional disorder, with occupancy factors for the α and β anomers of 0.77 and 0.23, respectively. The two torsion angles (Φ and Ψ) and the bridge angle (τ) that describe conformation of the glycosidic linkage between the galactopyran-o...
متن کامل2,6-Dichloro-9-(2′,3′,5′-tri-O-acetyl-β-d-ribofuranosyl)-9H-purine
The title synthetic analog of purine nucleosides, C16H16Cl2N4O7, has its acetyl-ated β-furan-ose ring in a 3'β-envelope conformation, with the corresponding C atom deviating by 0.602 (5) Å from the rest of the ring. The planar part of the furan-ose ring forms a dihedral angle of 65.0 (1)° with the mean plane of the purine bicycle. In the crystal, mol-ecules form a three-dimensional network thro...
متن کاملSynthesis and hybridization studies of oligonucleotides containing 1-(2-deoxy-2-α-C-hydroxymethyl-β-d-ribofuranosyl)thymine (2′-α-hm-dT)
We report the first investigation of oligoribonucleotides containing a few 1-(2-deoxy-2-alpha-C-hydroxymethyl-beta-D-ribofuranosyl)thymine units (or 2'-hm-dT, abbreviated in this work as 'H'). Both the 2'-CH2O-phosphoramidite and 3'-O-phosphoramidite derivatives of H were synthesized and incorporated into both 2',5'-RNA and RNA chains. The hybridization properties of the modified oligonucleotid...
