This third edition is a comprehensive and extended study about the best known approaches for preparing the main types of glycosides, covering the classic and more recent glycosylation reactions used for preparing simple and challenging glycosides currently used as potent antiviral and antineoplastic drugs, or fluorogenic substrates used for enzymatic detection in cell biology. Besides, this new edition provides more examples of the glycosidic methodologies followed for preparing complex glycoconjugates such as glycoproteins and glycosphingolipids and gangliosides used as adjuvants or as synthetic vaccines candidates. Also, additional mechanistic evidence is presented for better understanding of the glycosylation reaction, trying to identify the variables mainly depending on protecting and leaving groups, as well as catalyst and reaction condition which altogether directs the anomeric stereo control. A chapter on the glycoside hydrolysis is included in view of the increasing interest in the use of biomass as a natural and renewable source for obtaining important intermediates or products used in food or valuable materials. The author includes information in the characterization of glycosides section with the aim of giving additional tools for the structural assignment through NMR, X-Ray and mass spectra techniques.

In recent years C-glycoside chemistry has been one of the main topics in carbohydrate chemistry, not only because of the synthetic challenges posed, but also because C-glycosides have the potential to serve as carbohydrate analogues resistant to metabolic processes. Consequently, this class of compounds is currently receiving much interest as a potential source of therapeutic agents for clinical use. This book provides a broad coverage of the various synthetic methods available for the preparation of C-glycosides, and illustrates the interesting breadth of connections between carbohydrate chemistry and modern general synthetic organic chemistry by including topics such as transition-metal catalysis, radical chemistry, cycloaddition and rearrangement processes. In addition, in the final chapter of the book, the syntheses of C-di and trisaccharides reported through 1994 are reviewed. This well organised account of the synthetic chemistry in this field will prove to be very valuable to a wide range of researchers and advanced students, both as an introduction to the topic and for reference.

Chemistry of the O-glycosidic Bond: Formation and Cleavage focuses on the compositions, characteristics, formation, and reactions of O-glycosidic bonds, including the synthesis of oligosaccharides and polysaccharides. The publication first offers information on the characteristics and formation of O-glycosidic bonds, as well as the Fischer, Koenigs-Knorr, orthoester, and oxazoline methods. The text also looks at the synthesis of oligosaccharides. Concerns include evaluation of methods of glycosylation from the oligosaccharide synthesis viewpoint; stepwise propagation of oligosaccharide chains; and synthesis of disaccharides and higher oligosaccharides. The manuscript analyzes the synthesis of polysaccharides, including polycondensation, cationic polymerization, and synthesis of branched polysaccharides from linear ones. The book also reviews miscellaneous glycoside synthesis and cleavage of O-glycosidic bonds. Topics include synthesis of sugar anhydrides and aryl glycosides and acid-catalyzed hydrolysis. The text is a dependable reference for readers interested in O-glycosidic bonds.

Carbon analogs of carbohydrates, dubbed C-glycosides, have remained an important and interesting class of mimetics, be it in natural product synthesis, for pharmacological applications, as conformational probes, or for biological studies. C-Furanosides: Synthesis and Stereochemistry provides a much-needed overview of synthetic and stereochemical principles for C-furanosides: analogs of a 5-membered ring carbohydrate glycoside (furanoside), in which the anomeric oxygen has been replaced with a carbon. While our understanding of conformational behavior and of stereoselective synthesis in 6-membered ring compounds is quite good, our ability to predict the conformation of 5-membered ring compounds, or to predict the stereochemical outcome of a given reaction, remains anecdotal. Through a comprehensive review of literature approaches to the different C-furanoside stereoisomers, as well as an interpretation of the outcome in terms of a reasonable number of stereochemical models, C-Furanosides: Synthesis and Stereochemistry enables the reader to determine the best approach to a particular C-glycoside compound, and also hopes to provide a certain level of rationalization and predictability for the synthesis of new systems. Provides a comprehensive review of the growing literature in C-furanosides Enables readers to choose the most convenient approach to access a defined target in natural products synthesis or pharmacology and make reasonable predictions for the stereochemical outcome in unpublished cases Explores the various rational models for stereochemical analysis of furanoside reactivity, with a clear distinction made between physical chemical mechanisms and stereochemical models

Modern Methods in Carbohydrate Synthesis presents in one volume a sequence of chapters leading from classical methods through to today's newest state-of -the-art technology for oligosaccharide synthesis. It places particular emphasis on the most recent breakthroughs in the field, including emerging technologies for both oligosaccharide and glycoconjugate synthesis. Chapters describing the synthesis of increasingly important glycosidic linkage analogs, as well as the oligosaccharides containing derivatives and analogs of natural sugars are included. While chemical-synthetic methods constitute the major part of the book, completing the volume is a section on the rapidly expanding and important field of enzymatic synthesis, also covering combined chemical and enzymatic synthesis. Chapters are written by leading experts in the field. Wherever possible, methods of synthesis are provided in sufficient detail to allow the reader to implement the techniques described. More than 1700 references are provided in the 21 chapters comprising the book. This volume should provide a wealth of information to a large number of synthetic organic chemists, medicinal chemists, protein chemists, biochemists, glycobiologists and cell biologists, including students in these fields.

As a reflection of the quantum leap that has been made in the study of glycostructures, the first edition of this book has been completely revised and updated. The editors give up-to-date information on glycostructures, their chemistry and chemical biology in the form of a completely comprehensive survey. Glycostructures play highly diverse and crucial roles in a myriad of organisms and important systems in biology, physiology, medicine, bioengineering and technology. Only in recent years have the tools been developed to partly understand the highly complex functions and the chemistry behind them. While many facts remain undiscovered, this MRW has been contributed to by a large number of the world’s leading researchers in the field.

The synthesis of very complex saccharide structures is one of the most challenging areas of modern glycoscience. This volume presents the state of the art of complex carbohydrate synthesis, written by leading scientists whose groups are making major contributions in the field. Reflecting the particular interest in inhibitors and modulators as well as in mimetics, an in-cepth treatment is given both of their selective syntheses and of their biological implications. In addition the concept of multivalent glycoconjugate recognition as well as supramolecular implications of amphiphilic carbohydrates are highlighted.

A comprehensive summary of novel approaches to the stereoselective construction of glycosidic linkages, covering modern glycosylation methods and their use and application in natural product synthesis and drug discovery. Clearly divided into five sections, the first describes recent advances in classical methodologies in carbohydrate chemistry, while the second goes on to deal with newer chemistries developed to control selectivity in glycosylation reactions. Section three is devoted to selective glycosylation reactions that rely on the use of catalytic promoters. Section four describes modern approaches for controlling regioselectivity in carbohydrate synthesis. The final section focuses on new developments in the construction of "unusual" sugars and is rounded off by a presentation of modern procedures for the construction of glycosylated natural products. By providing the latest advances in glycosylation as well as information on mechanistic aspects of the reaction, this is an invaluable reference for both specialists and beginners in this booming interdisciplinary field that includes carbohydrate chemistry, organic synthesis, catalysis, and biochemistry.
