N-(2-Nitro­phenyl­sulfonyl)glycine methyl ester

The structure of the title compound, C₉H₁₀N₂O₆S, has been determined as part of an ongoing investigation into the preparation of N-allyl-substituted amino acids suitable for alkene cross-metathesis reactions in the generation of combinatorial libraries. The conformational structure is determined by intra- and intermolecular N—H...O and C—H...O hydrogen-bonding interactions.

Methyl 2,3,4-tri-O-acetyl-1-azido-1-deoxy-β-D-gluco­pyran­uronate at room temperature

The structure of the title compound, C₁₃H₁₇N₃O₉, has been determined as part of our continuing investigation into the development of modified sugar amino acid (SAA) scaffolds for dyamic combinatorial libraries of cyclic oligomers. The title compound serves as a viable synthetic precursor and a building block for the synthesis of reversible β-glucosidase inhibitors utilizing target-accelerated in situ click methodologies. The overall structure is stabilized by a number of C—H...O interactions.

N-(2-Nitro­benzene­sulfonyl)-L-alanine methyl ester

The structure of the title compound, C₁₀H₁₂N₂O₆S, has been determined as part of an ongoing investigation into the preparation of substituted amino acids suitable for the generation of combinatorial libraries. The molecular conformation is stabilized by intra- and intermolecular N—H...O and C—H...O hydrogen-bonding interactions.

Methyl 3,4-O-dibenzoyl-2-O-benzyl-1-thio-β-L-fucopyran­oside

The title compound, C₂₈H₂₈O₆S, is a protected fucose donor, synthesized as part of our investigations into the preparation of complex oligosaccharides. The benzoyl groups are equatorial and axial, while the thio­ether and ether groups are equatorial. The carboxyl­ate O atoms form a number of intra- and inter­molecular C—H...O inter­actions.
