There is a vast and often bewildering array of synthetic methods and reagents available to organic chemists today. The Best Synthetic Methods series allows the practising synthetic chemist to choose between all the alternatives and assess their real advantages and limitations. Each chapter in Carbohydrates details a particular theme associated with carbohydrate synthesis. A brief review of the subject area is provided, but the emphasis in all cases is on describing efficient practical methods to effect the transformations described. In order for the roles of carbohydrates to be thoroughly analysed and assessed, glycobiologists require access to defined target carbohydrates in useful quantities. Thus carbohydrates and glycoconjugates are now recognized as important targets for total synthesis programmes and it is essential to develop efficient regio- and stereoselective methods for the synthesis of carbohydrates. Whilst carbohydrates can sometimes be isolated from natural sources, synthetic strategies often offer the advantage of allowing access to larger quantities of material as well as entry to analogues of the natural carbohydrates. The latest volume in the long standing Best Synthetic Methods series Clear chapter by chapter breakdown of carbohydrate synthesis themes with examples of good practical methods for common carbohydrate syntheses

Solid-phase synthesis of carbohydrates presents unique challenges to synthetic chemists and currently represents one of the hottest areas of research in bioorganic chemistry. Solid Support Oligosaccharide Synthesis and Combinatorial Carbohydrate Libraries addresses the exciting expectation that solid-phase assembly of oligosaccharides will have a fundamental impact on the field of glycobiology. This publication details the methodologies currently investigated for the attachment of carbohydrates to beads, synthesis including coupling strategies, and removal of the product from beads. With chapters written by eminent contributing authors, the material explores different synthetic strategies, glycosylation protocols, the use of solid supports versus soluble polymeric supports, and "on-resin" analytical methods. Tremendous progress in the field has set the stage for Solid Support Oligosaccharide Synthesis and Combinatorial Carbohydrate Libraries to provide a wealth of information on such topics as: Specific oligosaccharide structures used in signal transduction processes Preparation and screening of glycopeptide libraries Solid-phase carbohydrate synthesis
