چکیده انگلیسی
MS and 1H, 13C and 11B NMR results are presented revealing the formation of cyclic seven-membered boronate structures at trans-1,2-diol moieties of carbohydrates providing new opportunities for the activation, protection and analysis of glucopyranose-based oligomers and polymers such as cellulose or starch. 'Coordination-induced shifts' in 13C NMR spectra were identified for the esterification by boronic acids of carbohydrates, which can be applied for further studies.
