Highly selective reaction of methyl tetra-O-pivaloyl-beta-D-glucopyranuronate 2 with iodotrimethylsilane or (Me3Si)2 and I2 affords, in excellent yield, the 'disarmed' glycosyl iodide 1 which has good stability at 20 degrees C and excellent stability at 0 degrees C; the X-ray crystal structure of 1 is described, along with a comparison of its utility as a glycosyl donor to that of the corresponding bromide.

The mechanism of attachment of Na(+) on glucose, methyl-alpha-D-glucose, methyl-beta-D-glucose, 3-O-methylglucose, tetra-O-methylglucose, and also on galactose and methyl-beta-D-galactose, was studied. For this we measured the ion yields for the complex [sugar-Na(+)] formed by ionisation by matrix-assisted laser desorption/ionisation (MALDI) and ionspray. These data were compared with the relative volatilities and hydrophobicities of the sugars, measured by evaporative light scattering and reversed-phase liquid chromatography, respectively. Some formation enthalpies for the complexes [sugar-Na(+)], starting from the sugar and the cation, were obtained by ab initio calculations. No simple correlations could be observed between the ion yields and the parameters studied, so that the cationisation mechanism of the sugars remains unclear.
