1-O-Acetyl-3,4,6-tri-O-benzyl-2-C-bromomethyl-2-deoxy-α-d-glucopyranose
In the title compound, C30H33BrO6, the pyran-ose ring adopts a chair conformation. Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1 (2) and 64.6 (2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.9 (2)° to this C/C/C/O plane. Th...

متن کاملp-Tolyl 2-O-benzoyl-3-O-benzyl-4,6-O-benzylidene-1-thio-α-l-idopyranoside
The title compound, C(34)H(32)O(6)S, is an ido-configured thio-glycoside building block for heparan sulfate fragments. It contains disordered tolyl and O-benzyl groups with occupancy ratios of 0.539 (13):0.461 (13) and 0.613 (13):0.387 (13), respectively, as determined from a weakly diffracting crystal. The fused rings adopt chair conformations with the mol-ecules packing into a three-dimension...
متن کاملPhenyl 2,3,4-tri-O-benzyl-1-thio-α-d-mannopyranoside monohydrate
In the title compound, C(33)H(34)O(5)S·H(2)O, the mannopyran-oside ring adopts a chair conformation with the 2-α-thio-phenyl group occupying an axial position. One of the pendant benzyl groups is disordered over two sets of sites in a 0.5:0.5 ratio. In the crystal, the water mol-ecule makes two O-H⋯O hydrogen bonds to an adjacent sugar mol-ecule with the O atoms of the primary alcohol and ether...
متن کامل1,3,4-Tri-O-acetyl-2-N-(trifluoroacetyl)-β-l-fucose
The title compound, C14H18F3NO8, was produced through conjugation of 1,3,4-tri-O-acetyl-2-azidode-oxy-α,β-l-fucose with tri-fluoro-acetyl chloride in the presence of bis-(di-phenyl-phosphino)ethane in tetra-hydro-furan at room temperature. The X-ray crystal structure reveals that the β-anomer of the product mixture crystallizes from ethyl acetate/hexa-nes. The compound exists in a typical chair...
