Abstract
Keto sugar nucleotides (KSNs) are common and versatile precursors to various deoxy sugar nucleotides, which are substrates for the corresponding glycosyltransferases involved in the biosynthesis of glycoproteins, glycolipids, and natural products. However, there has been no KSN synthesized chemically due to the inherent instability. Herein, the first chemical synthesis of the archetypal KSN TDP-4-keto-6-deoxy-d-glucose (1) is achieved by an efficient and optimized route, providing feasible access to other KSNs and analogues, thereby opening a new avenue for new applications.

Abstract
The synthesis of a carbohydrate building block usually starts with introduction of a temporary protecting group at the anomeric center and ends with its selective cleavage for further transformation. Thus, the choice of the anomeric temporary protecting group must be carefully considered because it should retain intact during the whole synthetic manipulation, and it should be chemoselectively removable without affecting other functional groups at a late stage in the synthesis. Etherate groups are the most widely used temporary protecting groups at the anomeric center, generally including allyl ethers, MP (p-methoxyphenyl) ethers, benzyl ethers, PMB (p-methoxybenzyl) eithers, and silyl ethers. This chapter provides a comprehensive review on their formation, cleavage, and applications in the synthesis of complex carbohydrates.

Abstract
Self-assembled monolayers (SAMs) decorated with photoisomerizable azobenzene glycosides are useful tools for investigating the effect of ligand orientation on carbohydrate recognition. However, photoswitching of SAMs between two specific states is characterized by a limited capacity. The goal of this study is the improvement of photoswitchable azobenzene glyco-SAMs. Different concepts, in particular self-dilution and rigid biaryl backbones, have been investigated. The required SH-functionalized azobenzene glycoconjugates were synthesized through a modular approach, and the respective glyco-SAMs were fabricated on Au(111). Their photoswitching properties have been extensively investigated by applying a powerful set of methods (IRRAS, XPS, and NEXAFS). Indeed, the combination of tailor-made biaryl-azobenzene glycosides and suitable diluent molecules led to photoswitchable glyco-SAMs with a significantly enhanced and unprecedented switching capacity.

Abstract
Molecular recognition of mannose-6-phosphate (M6P)-modified oligosaccharides by transmembrane M6P receptors is a key signaling event in lysosomal protein trafficking in vivo. Access to M6P-containing high-mannose N-glycans is essential to achieving a thorough understanding of the M6P ligand-receptor recognition process. Herein we report the application of a versatile and reliable chemical strategy to prepare asymmetric di-antennary M6P-tagged high-mannose oligosaccharides in >20% overall yield and in high purity (>98%). Regioselective chemical glycosylation coupled with effective phosphorylation and product purification protocols were applied to rapidly assemble these oligosaccharides. The development of this synthetic strategy simplifies the preparation of M6P-tagged high-mannose oligosaccharides, which will improve access to these compounds to study their structures and biological functions.

Abstract
The oligosaccharide phosphate fraction (OPF) obtained from mild acid hydrolysis of P. holstii NRRL Y-2448 phosphomannan is the starting material for the preparation of the Phase III anticancer drug candidate PI-88. The OPF was for the first time successfully separated by preparative ion exchange chromatography and the major oligosaccharides isolated and characterized by NMR spectroscopy. The components were also acetylated and subjected to LC-MS analysis. These studies revealed that the OPF also contained all-α(1 → 3)-linked oligosaccharides in addition to the known α(1 → 3)/(1 → 2)-linked species, most likely formed by hydrolysis of the latter. Contrary to previous assumptions, the only phosphorylated disaccharide present is α(1 → 3)-linked. In addition, it was determined that a glycosylamine derivative previously isolated is, in fact, a manufacturing byproduct formed from exposure to aqueous ammonium bicarbonate during chromatographic purification. Based on these findings a new generic structure for PI-88 is proposed which more accurately reflects its composition.

Abstract
Efficient sialylations using N-glycolylneuraminic acid (Neu5Gc) phosphite donors having an acetyl or benzyl group on the glycolyl moiety are described in the synthesis of Neu5Gc-containing glycans. Both phosphite donors 1 and 2 were readily coupled with primary and secondary acceptor alcohols in propionitrile at -78 degrees C to provide the desired glycosides with good alpha-selectivities.

Abstract
An improved synthetic route to α(1→3)/α(1→2)-linked mannooligosaccharides has been developed and applied to a more efficient preparation of the potent anti-angiogenic sulfated pentasaccharide, benzyl Manα(1→3)-Manα(1→3)-Manα(1→3)-Manα(1→2)-Man hexadecasulfate, using only two monosaccharide building blocks. Of particular note are improvements in the preparation of both building blocks and a simpler, final deprotection strategy. The route also provides common intermediates for the introduction of aglycones other than benzyl, either at the building block stage or after oligosaccharide assembly. The anti-angiogenic activity of the synthesized target compound was confirmed via the rat aortic assay.

Abstract
A stepwise synthetic route to the mannooligosaccharides from the neutral fraction of Pichia holstii phosphomannan hydrolysate, including a tetrasaccharylamine component, was developed using only two or three readily available d-mannose building blocks. These compounds were sulfonated to give the corresponding sulfated oligosaccharides which are closely related to the constituents of the anticancer agent PI-88. The synthetic approach is well suited to the preparation of analogues as demonstrated by the synthesis of a series of (1-->3)-linked mannooligosaccharides. The inhibitory activity of the sulfated oligosaccharides against heparanase was determined using a Microcon ultrafiltration assay. The tetra- and pentasaccharides were potent competitive inhibitors of heparanase (K(i)=200-280nM) whilst the shorter di- and trisaccharides were partial competitive inhibitors and did not completely inhibit the enzyme even at very high concentrations.
