Formation and synthetic applications of carbohydrate-iron complexes possessing C-metal bond are discussed. Some of these intermediates are stable and can be isolated and characterized. In many instances, however, the sugar carbon-iron complexes exhibit a limited stability and are directly converted into the final products without their prior isolation and characterization. Nevertheless, the presence of such complexe Read More

The monosaccharide derivatives containing the C-Sn and C-Li bonds are reviewed. Both types of these organometallics are useful intermediates in the synthesis of variety of optically pure compounds such as higher carbon sugars, C-disaccharides, carbocyclic derivatives, etc.Organometallics containing the C-Sn bond are usually stable and can be isolated in the pure form, but their reactivity is low. The tin moiety in such comp Read More

The aim of this review is to discuss the accomplishments made in the area of the stereoselective formation of a 1,2-cis glycosidic bond. Importance of this subject derives primarily from the natural occurrence of numerous 1,2-cis-linked oligosaccharides, glycosides, and glycoconjugates, which are widely distributed in living tissues. These compounds are also found in the human milk, in blood group compounds, in bacterial lipop Read More

The molecular recognition of carbohydrates in water is an intriguing subject in view of the important role of saccharides in biological activities, such as intercellular recognition, signal transduction or as targets of bacterial / viral infection of cells. Considerable efforts have been directed toward understanding and mimicking such recognition processes, and developing effective agents to control these events. Driven by the need t Read More
