,Armed–Disarmed Effects in Carbohydrate Chemistry: History, Synthetic and Mechanistic Studies,ed by the chance events that laid the foundation for the armed–disarmed strategy for oligosaccharide assembly. A key mechanistic issue for this strategy was that, although both armed and disarmed entities could function independently as glycosyl donors, when one was forced to compete with the other

Effect of Electron-Withdrawing Protecting Groups at Remote Positions of Donors on Glycosylation Stedonors, rhamnopyranosyl donors, and 2,6-dideoxyglucopyranosyl donors. We discuss the equatorial α-directing effect of an electron-withdrawing group at the N-5 position of sialyl donors. The proposed mechanism and origin of some of the equatorial β-directing effects are described. We also review the

Influence of Protecting Groups on the Reactivity and Selectivity of Glycosylation: Chemistry of theed on the influence of the various protecting groups on stereoselectivity and these effects are interpreted in the framework of a general mechanistic scheme invoking a series of solvent-separated and contact ion pairs in dynamic equilibrium with a covalent α-glycosyl trifluoromethanesulfonate.

Uronic Acids in Oligosaccharide and Glycoconjugate Synthesis,t molecules, namely a pre-glycosylation oxidation approach, in which uronic acid building blocks are used, and a post-glycosylation oxidation strategy, which employs an oxidation step after the assembly of the oligosaccharide chain. Because uronic acid building blocks are generally considered to be
