A dense hydrogen-bond network is responsible for the mechanical and structural properties of polysaccharides. Random derivatization alters the properties of the bulk material by disrupting the hydrogen bonds, but obstructs detailed structure–function correlations. We have prepared well-defined unnatural oligosaccharides including methylated, deoxygenated, deoxyfluorinated, as well as carboxymethylated cellulose and chitin analogues with full control over the degree and pattern of substitution. Molecular dynamics simulations and crystallographic analysis show how distinct hydrogen-bond modifications drastically affect the solubility, aggregation behavior, and crystallinity of carbohydrate materials. This systematic approach to establishing detailed structure–property correlations will guide the synthesis of novel, tailor-made carbohydrate materials.

The attempted synthesis of several carbohydrate 1,2-diols is reported, together with the transformation of two of these diols into cyclic thiocarbonates, namely 4,6-O-benzylidene-3-O-methyl-1,2-O-thiocarbonyl-α-D-glucose and 3,4-O-isopropylidene-1,2-O-thiocarbonyl-β-D-arabinose.The treatment of these thiocarbonates, and a furanose 1,2-thiocarbonate previously prepared by Mukaiyama, with methyl halides and with tributyltin hydride is discussed.A single-crystal X-ray diffraction study of 3,4-O-isopropylidene-1,2-O)-thiocarbonyl-β-D-arabinose is recorded.
