,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
