, p. 228 - 238 (2018)
A series of compounds associated with naturally occurring and biologically relevant glycans consisting of α-mannosides were prepared and analyzed using collision-induced dissociation (CID), energy-resolved mass spectrometry (ERMS), and 1H nucle

The role of sulfur in glycosidic bonds has been evaluated using quartz crystal microbalance methodology. Synthetic routes towards α1-2- and α1-6-linked dimannosides with S- or O-glycosidic bonds have been developed, and the recognition properties assessed in competition binding assays with the cognate lectin concanavalin A. Mannose-presenting QCM sensors were produced using photoinitiated, nitrene-mediated immobilization methods, and the subsequent binding study was performed in an automated flow-through instrumentation, and correlated with data from isothermal titration calorimetry. The recorded Kd-values corresponded well with reported binding affinities for the O-linked dimannosides with affinities for the α1-2-linked dimannosides in the lower micromolar range. The S-linked analogs showed slightly disparate effects, where the α1-6-linked analog showed weaker affinity than the O-linked dimannoside, as well as positive apparent cooperativity, whereas the α1-2-analog displayed very similar binding compared to the O-linked structure.

Synthesis of laminin hexasaccharide analogue
Ding, Xianglan,Kong, Fanzuo
, p. 915 - 922 (2007/10/03)
The synthesis of laminin hexasaccharide analogue di-O-[Gal-β-(1→4)-Glc-β]-(1→2)-(1→6)-man-α- (1→6)-man-α-Me derivative (1) was achieved with 1,2-anhydromannopyranose benzyl ether (3) as the key intermediate. Coupling of 3 with methyl 2,3,4-tri-O-benzyl-α-D-mannopyranoside (4) promoted by ZnCl2 gave methyl 2,3,4-tri-O-benzyl-6-O-(3,4,6-tri-O-benzyl-α-D-mannopyranosyl)-α-D- mannopyranoside (2a). Selective 6-O-debenzylation of 2b with ZnCl2-Ac2O-HOAc followed by coupling with acetobromolactopyranose afforded 1.
Synthesis and glycosylation of pyrimidin-2-yl 1-thio-α-D-manno- and -α-L-rhamnopyranoside

, p. 135 - 139 (2007/10/03)
Pyrimidin-2-yl 2,3,4,6-tetra-O-benzyl-1-thio-α-D-mannopyrano side (9), pyrimidin-2-yl 2,3,4-tri-O-benzyl-α-L-rhamnopyranoside (10), pyrimidin-2-yl 2-O-acetyl-3,4,6-tri-O-benzyl-1-thio-α-D-mannopyranoside (7), and pyrimidin-2-yl 2-O-acetyl-3,4-di-O-benzyl-1-thio-α-L-rhamnopyranoside (8) were prepared almost quantitatively from the corresponding protected 1,2-O-methoxyethylidene-β-D-manno-or-β-L-rhamnopyranose with 2-mercaptopyrimidine in the presence of mercuric bromide. Coupling reactions of the thioglycosides promoted by silver triflate with suitable glycosyl acceptors afforded 1,2-trans linked disaccharides. Copyright (C) 1998 Elsevier Science Ltd.
