Polysaccharides are the structurally most complex of the major classes of biopolymers. While nucleic acids and proteins are linear assemblies, polysaccharides are structurally and stereochemically more diverse. Additional complexity is added to the polysaccharide structure by the formation of glycoconjugates such as glycolipids and glycoproteins. Oligosaccharides in the form of glycoconjugates mediate a variety of events, including inflammation, immunological response, metastasis, and fertilization. Cell surface carbohydrates act as biological markers of various tumors and as binding sites for other substances, including pathogens. The increased understanding of the important roles oligosaccharides and glycoconjugates play in fundamental life-sustaining processes has stimulated a need for access to usable quantities of these materials. Glycoconjugates commonly exist as microheterogeneous mixtures and are difficult to isolate in homogeneous form, therefore yielding only small amounts of the desired material. The problems associated with isolation from natural sources give rise to opportunities for chemical synthesis. The developments in synthetic carbohydrate chemistry have centered on finding solutions to two important challenges: the need to differentiate similar functionality (hydroxyl or amino) contained on each monosaccharide and the need to induce the selective formation of a variety of glycosidic linkages. Unlike linkages found in the other two classes of repeating biopolymers, each glycosidic bond to be fashioned in a growing oligosaccharide ensemble constitutes a new locus of stereogenicity. In re-
