6-Azido-3-O-benzyl-6-deoxy-N,N-diethyl-1,2-O-isopropylidene-d-glycero-α-d-gluco-heptofuranuronamide
Reaction of 3-O-benzyl-1,2-O-isopropyl-idene-α-xylo-pentodialdo-1,4-furan-ose with N,N-diethyl-2-(dimethyl-sulfuranil-idene)acetamide gave stereoselectively an ep-oxy-amide, which was regioselectively opened by NaN(3) in dimethyl formamide to give the title compound, C(21)H(30)N(4)O(6). X-ray crystallography confirmed the relative stereochemistry of the title compound and the absolute configura...
متن کامل[μ-10,21-Dimethyl-3,6,14,17-tetraazatricyclo[17.3.1.18,12]tetracosa-1(23),8(24),9,11,19,21-hexaene-23,24-diolato-κ8 N 3,N 6,O 23,O 24:N 14,N 17,O 23,O 24]bis[(nitrato-κ2 O,O′)nickel(II)]
In the title centrosymmetric dinuclear nickel complex, [Ni(2)(C(22)H(30)N(4)O(2))(NO(3))(2)], each of the two Ni(II) atoms has a distorted octa-hedral geometry, defined by two N atoms and two O atoms from the macrocyclic ligand and two O atoms from a chelating nitrate anion. The two Ni atoms are bridged by two phenolate O atoms, forming a four-membered Ni(2)O(2) ring.

The mol-ecule of the title compound, C(22)H(27)NO(9), an azasugar derivative, consists of one benzene ring and two fused rings, which have the cis arrangement at the ring junctions, and gives a V-shaped geometry. The inter-planar angle between the five- and six-membered rings is 65.69 (11)°. The crystal structure is stablized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کاملEthyl 3,6-di-O-benzyl-2-deoxy-N-phthalimido-1-thio-β-d-glucopyranoside
In the title compound, C(30)H(31)NO(6)S, the plane of the N-phthalimido group is nearly orthogonal to the least-squares plane of the sugar ring (defined by atoms C2, C3, C5 and O5 using standard glucose nomenclature), making a dihedral angle of 72.8 (1)°. The thio-ethyl group has the exo-anomeric conformation. The hy-droxy group forms an inter-molecular hydrogen bond to the O atom in the sugar ...
متن کامل2-N-Benzyl-2,6-dideoxy-2,6-imino-3,4-O-isopropylidene-3-C-methyl-d-allononitrile
X-ray crystallography firmly established the relative stereochemistry of the title compound, C(17)H(22)N(2)O(3). The absolute configuration was determined by use of 2-C-methyl-d-ribonolactone as the starting material. The compound exists as O-H⋯N hydrogen-bonded chains of mol-ecules running parallel to the a-axis.
