  Comparative investigations on the regioselective mannosylation of 2,3,4-triols of mannose

  摘要：

  Regioselective glycosylation of 2,3,4-unprotected benzyl alpha-D-mannopyranoside and allyl alpha- and -beta-D-mannopyranosides has been investigated. The configuration at the anomeric centre influences the outcome of the reaction. Possible role of hydrogen-bonding network in glycosylation of the above triols used as glycosidic acceptors is discussed. (C) 2008 Elsevier Ltd. All rights reserved.
