Abstract
Advances in carbohydrate chemistry have certainly made common oligosaccharides much more accessible. However, many current methods still rely heavily upon specialized knowledge of carbohydrate chemistry. The application of automated technologies to chemical and life science applications such as genomics and proteomics represents a vibrant field. These automated technologies also present opportunities for their application to organic synthesis, including that of the synthesis of oligosaccharides. However, application of automated methods to the synthesis of carbohydrates is an underdeveloped area as compared to other classes of biomolecules. The overarching goal of this review article is to present the advances that have been made at the interface of carbohydrate chemistry and automated technology.

Abstract
The mechanism of solvent effects on the stereoselectivity of glycosylation reactions is investigated using quantum-mechanical (QM) calculations and molecular dynamics (MD) simulations, considering a methyl-protected glucopyranoside triflate as a glycosyl donor equivalent and the solvents acetonitrile, ether, dioxane, or toluene, as well as gas-phase conditions (vacuum). The QM calculations on oxacarbenium-solvent complexes do not provide support to the usual solvent-coordination hypothesis, suggesting that an experimentally observed β-selectivity (α-selectivity) is caused by the preferential coordination of a solvent molecule to the reactive cation on the α-side (β-side) of the anomeric carbon. Instead, explicit-solvent MD simulations of the oxacarbenium-counterion (triflate ion) complex (along with corresponding QM calculations) are compatible with an alternative mechanism, termed here the conformer and counterion distribution hypothesis. This new hypothesis suggests that the stereoselectivity is dictated by two interrelated conformational properties of the reactive complex, namely, (1) the conformational preferences of the oxacarbenium pyranose ring, modulating the steric crowding and exposure of the anomeric carbon toward the α or β face, and (2) the preferential coordination of the counterion to the oxacarbenium cation on one side of the anomeric carbon, hindering a nucleophilic attack from this side. For example, in acetonitrile, the calculations suggest a dominant B2,5 ring conformation of the cation with preferential coordination of the counterion on the α side, both factors leading to the experimentally observed β selectivity. Conversely, in dioxane, they suggest a dominant (4)H3 ring conformation with preferential counterion coordination on the β side, both factors leading to the experimentally observed α selectivity.

Abstract
A new method for oligosaccharide assembly that combines the advantages of one-pot synthesis and fluorous separation is described. After one-pot glycosylations are completed, a fluorous tag is introduced into the reaction mixture to selectively "catch" the desired oligosaccharide, which is rapidly separated from non-fluorous impurities by fluorous solid-phase extraction (F-SPE). Subsequent "release" of the fluo rous tag and F-SPE achieved the purification of the desired oligosaccharide without the use of time- and solvent-consuming silica gel chromatography. Linear and branched oligosaccharides have been synthesized with this approach in just a few hours (for the overall oligosaccharide assembly and purification process).

Abstract
2,3-trans-Carbamate- and -carbonate-carrying pyranosides were very easily anomerised from the beta to the alpha direction in the presence of a Lewis acid compared to other pyranosides. This reaction is caused by endocyclic cleavage of the pyranosides. Evidence for endocyclic cleavage of conformationally restricted pyranosides in the chair form was obtained by intra- and intermolecular Friedel-Crafts reactions, chloride addition, and reduction of the generated cation. On the other hand, pyranosides with the distorted conformation were never cleaved in an endocyclic manner.

Abstract
A new method using a light-fluorous glycosyl donor and an orthogonal tagging strategy to synthesize oligosaccharides and glycoconjugates has been developed. The glycosyl donor orthogonally protected with a C8F17-silyl tag and benzoyl groups was reacted with excess amounts of glycosyl acceptor. Fluorous solid-phase extraction separated the glycosylated product and unreacted glycosyl acceptor. This new protocol has high reaction efficiency and easy separation, which was demonstrated in the synthesis of an unprotected trisaccharide and an O-glycosylated serine in this paper.

Abstract
This review is the second update of the original review on the application of MALDI mass spectrometry to the analysis of carbohydrates and glycoconjugates that was published in 1999. It covers fundamental aspects of the technique as applied to carbohydrates, fragmentation of carbohydrates, studies of specific carbohydrate types such as those from plant cell walls and those attached to proteins and lipids, studies of glycosyl-transferases and glycosidases, and studies where MALDI has been used to monitor products of chemical synthesis. Use of the technique shows a steady annual increase at the expense of older techniques such as FAB. There is an increasing emphasis on its use for examination of biological systems rather than on studies of fundamental aspects and method development and this is reflected by much of the work on applications appearing in tabular form.

Abstract
The synthesis of complex oligosaccharides has been a challenge for researchers. Herein, we describe a strategy for the synthesis of an activated oligomannan 1 that employs ionic liquid (IL) support glycosylation methodology on an IL-tagged mannosyl fluoride donor. This method is capable of rapidly producing linear alpha(1-->6) oligomannan thioglycosides in a convenient and cost-effective manner without the need of column purification after each glycosylation step.

Abstract
This paper reports a new strategy for oligosaccharide synthesis by combining solid-phase methods with cap and capture-release separation techniques, using the p-(5-(ethoxycarbonyl)pentyloxy)benzyl group (CPB) as a tag for the capture of desired oligosaccharides. After a complex carbohydrate mixture was obtained by solid-phase synthesis, the desired oligosaccharide containing a free carboxyl group derived from CPB was attached to an amino resin. The loaded resin was readily separated from side products by filtration and finally treated with acid to release the pure oligosaccharide product.

Abstract
A strategy for facile oligosaccharide synthesis is described. It obviates chromatographic separation of intermediates and enables the isolation of desired oligomers with capture-release purification and reverse-phase silica-gel cartridge separation. As an example, preparation of monoglucosylated mannotetraose (Glc alpha1-->3Man alpha1-->2Man1alpha-->2Man1alpha-->3Man beta) was conducted. After sequential glycosylation, capture-release purification with Cys-resin, global deprotection, and reverse-phase silica-gel cartridge separation, the target pentasaccharide was isolated, while isolation of shorter oligomers that lack nonreducing-end residues (Man alpha1-->2Man1alpha-->2Man1alpha-->3Man beta, Man1alpha-->2Man1alpha-->3Man beta, Man1alpha-->3Man beta) was also achieved. These products were connected to a thiol-containing linker and immobilized on Au-coated chips. Their affinity to recombinant calreticulin was evaluated by quartz-crystal microbalance.

Abstract
Bisubstrate-type inhibitors for N-acetylglucosaminyltransferase (GnT)-V and -IX were designed and synthesized. These compounds carry both an acceptor trisaccaride and an UDP-GlcNAc component tethered by a linker of variable length. The acceptor trisaccharide unit was constructed using a combination of a polymer support and a resin capture-release strategy. Namely, starting with a beta-mannoside bound to low molecular weight monomethyl PEG (MPEG), successive glycosylations with donors having chloroacetyl group produced the trisaccharide, which was subjected to the capture-release purification using cysteine loaded resin. UDP-GlcNAc units carrying phosphate moieties were separately synthesized from the bromoacetamide-containing glucosamine derivative. Ligation between the acceptor thiol and each alkyl bromide on the donor unit readily proceeded, and produced the coupling product. The introduction of the UMP component gave target compounds. All of the synthesized compounds had significant activities to GnT-V and -IX. Their potencies were dependent upon the linkers length. GnT-IX was more sensitive to these inhibitors and optimum linker length was clearly different between these GnTs. The most potent inhibitor of GnT-V had Ki=18.3 microM, while that of GnT-IX had Ki = 4.7 microM.

Abstract
Solid-phase oligosaccharide synthesis is based on a hydroxymethylbenzyl benzoate spacer linker which is connected to the Merrifield resin (1 P). Glycosylation was performed with O-glycosyl trichloroacetimidates of glucosamine, mannose, and galactose permitting chain extension (2e, 5e), branching (4b, 7b, 8b), and chain termination (3t, 6t, 9t) with the use of O-benzyl, O-benzoyl, and N-dimethylmaleoyl as permanent and O-fluorenylmethoxycarbonyl (Fmoc) and O-phenoxyacetyl (PA) as temporary protecting groups. The steps required on solid phase are i) glycosylation under TMSOTf catalysis, ii) selective cleavage of the temporary protecting groups, Fmoc with NEt3 and PA with 0.5 equivalents of NaOMe in CH2Cl2/MeOH, and iii) product cleavage from the resin with 4.0 equivalents of NaOMe in CH2Cl2/MeOH and following O-acetylation for convenient product isolation. Thus a highly successful synthesis of a small library of seventeen N-glycan structures was made possible comprising the N-glycan pentasaccharide core structure 53 and two further chain extended hexa- and heptasaccharide N-glycans with a glucosamine or a lactosamine residue, respectively, which is attached to one of the mannose residues of the core structure (56 and 59).

Abstract
The biological functions of a variety of proteins are regulated by heparan sulfate glycosaminoglycans. In order to facilitate the elucidation of the molecular basis of glycosaminoglycan-protein interactions we have developed syntheses of heparin-like oligosaccharides on polymer supports. A completely stereoselective strategy previously developed by us for the synthesis of these oligosaccharides in solution has been extended to the solid phase using an acceptor-bound approach. Both a soluble polymer support and a polyethylene glycol-grafted polystyrene resin have been used and different strategies for the attachment of the acceptor to the support have been explored. The attachment of fully protected disaccharide building blocks to a soluble support through the carboxylic group of the uronic acid unit by a succinic ester linkage, the use of trichloroacetimidates as glycosylating agents and of a functionalized Merryfield type resin for the capping process allowed for the construction of hexasaccharide and octasaccharide fragments containing the structural motif of the regular region of heparin. This strategy may facilitate the synthesis of glycosaminoglycan oligosaccharides by using the required building blocks in the glycosylation sequence.

Abstract
Glycosylation is one of the most important post-translation modifications of proteins, which affects biological activities by way of controlling higher order structure. Recently, the novel structure of glycoprotein, namely C-glycosyl protein was identified in various proteins. The first total synthesis of the naturally occurring C-glycosyl amino acid and peptide was achieved. The mannose and tryptophan moiety was connected via ring opening reaction of epoxide by lithiated indole derivative. After functional group conversion and deprotection, the glyco-amino acid was synthesized in a concise and stereoselective manner. To develop the rapid oligosaccharide construction methodology, the soluble polymer supported oligosaccharide was investigated. Due to high polarity of polymer support, the purification of PEG bound compound is achieved quite easily. The real-time monitoring of the glycosylation reaction was performed by MALDI-TOF MS, whereas the deprotection reaction of chloroacetyl group was performed by color test using (p-nitrobenzyl) pyridine. The purification of PEG bound compound which has chloroacetyl group, is achieved by capture-release strategy by use of resin bound cysteine derivative. By combination of these methodologies and novel linker, tetrasaccharides were synthesized.
