Реферат: Supramer analysis was applied to explain the earlier discovered phenomenon of the transformation of nonselective glycosylation into stereospecific one upon changing the glycosyl donor concentration. The supramer analysis is a part of the supramer approach being developed by us and makes it possible to find concentration ranges separated by “critical” concentrations at which supramolecular aggregates (supramers) have different structures. As a result, the “critical” concentration for solutions of 2,3,5-tri-O-benzoyl-α-D-arabinofuranosyl bromide (1) in acetonitrile was found by polarimetry, and that for solutions of glycosyl bromide 1 in 1,2-dichloroethane (DCE) was found using static light scattering. The presence of nanosized supramers in solutions of 1 in acetonitrile and nano- and mesoscale supramers in solutions of 1 in DCE was demonstrated using dynamic light scattering. An analysis of the obtained experimental and earlier published data suggested a possibility of both formation of halogen bonds involving DCE molecules and halogen bond-mediated supramolecular aggregation of molecules of the dissolved substance in this solvent.
