Crystal packing in three related disaccharides: precursors to heparan sulfate oligosaccharides.

ABSTRACT: The three title compounds form part of a set of important precursor dissacharides which lead to novel therapeutics, in particular for Alzheimer's disease. All three crystallize as poorly diffracting crystals with one independent mol-ecule in the asymmetric unit. Two of them are isostructural: 4-meth-oxy-phenyl 4-O-[6-O-acetyl-2-azido-3-O-benzyl-2-de-oxy-4-O-(9-fluor-en-yl-methyl-oxycarbon-yl)-α-d-gluco-pyranos-yl]-2-O-benzoyl-3-O-benzyl-6-O-chloro-acetyl-α-l-ido-pyran-oside, C59H56ClN3O16, (I), the ido-relative of a reported gluco-disaccharide [Gainsford et al., 2013 ▶). Acta Cryst. C69, 679-682] and 4-meth-oxy-phenyl 4-O-[6-O-acetyl-2-azido-3-O-benzyl-2-de-oxy-4-O-(9-fluorenyl-methyl-oxycarbon-yl)-α-d-gluco-pyranos-yl]-2-O-benzoyl-3-O-benzyl-6-O-meth-oxy-acetyl-α-l-ido-pyran-oside, C60H59
