Article abstract of DOI:10.1016/0040-4039(94)88436-6

An efficient synthesis of the title compound, per-6-bromo-per-2,3-dimethyl-β-cyclodextrin, is described, giving access to a highly soluble cyclodextrin, which may be used for further chemical modification of β-cyclodextrin.Crystals of the target compound were grown and the solid state structure was determined by X-ray crystallography, revealing a cyclodextrin derivative whose conformation deviates substantially from C₇ symmetry.
