摘要：

MS and H-1, C-13 and B-11 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. (C) 2008 Elsevier Ltd.
