This second volume in a series offers a collection of synthetic procedures valuable to the practice of synthetic carbohydrate chemistry, both for specific synthetic transformations and the preparation of common synthetic intermediates. Each chapter presents in-depth experimental descriptions for the reported procedures, including reaction setup, reaction conditions, work-up procedures, and purification protocols. All described procedures have been independently verified as reliable and reproducible. With editors and contributors who are highly respected scientists in the field, this book…mehr

Series Editor:Pavol Ková¿, Ph.D., Dr. h.c., obtained his Ph.D. in organic chemistry at the Institute of Chemistry, Slovak Academy of Sciences, Bratislava. Dr. Ková¿ is a strong promoter of good laboratory practices and a vocal critic of the publication of experimental chemistry lacking data that allow reproducibility. He has more than 40 years of experience in carbohydrate chemistry and over 280 papers published in refereed scientific journals, several patents, and book chapters. He joined the National Institutes of Health (NIH) (Bethesda, Maryland) in 1983 where he is currently one of the principal investigators and chief of the Section on Carbohydrates (NIDDK, Laboratory of Bioorganic Chemistry). The world's oldest research group continuously working on chemistry, biochemistry, and immunology of carbohydrates, it was originally established by the American carbohydrate chemist Claude S. Hudson. Ková¿'s main interest is the development of conjugate vaccines for bacterial diseases from synthetic carbohydrate antigens. Volume Two Editors: Jeroen Codée obtained his Ph.D. from Leiden University, the Netherlands, under the guidance of Jacques van Boom and Stan van Boeckel in 2004. Codée then moved to the Eidgenossische Technische Hochschule (ETH) Zurich, Switzerland, for a two-year post-doctoral stay with Peter Seeberger. He subsequently returned to Leiden University, where he is now an associate professor in bio-organic chemistry. His research focuses on glycochemistry and glycobiology, ranging from fundamental organic synthesis to vaccine/drug development and the development of glycobiology tools. He has authored or co-authored more than 70 publications and seven book chapters. Gijs van der Marel conducted his Ph.D. studies on DNA chemistry with Jacques van Boom and received his Ph.D. degree in 1981 from Leiden University, the Netherlands. He has remained associated with this university, where he is now a full professor in synthetic organic chemistry. He has supervised more than 70 Ph.D. students and authored or co-authored over 700 papers. His research focuses on all synthetic aspects of biopolymers, including nucleic acids, peptides, and carbohydrates, and hybrids and analogues thereof.
