Book Description
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

Book Description
This text provides experimental methods for a wide range of organic reactions, systematically arranged according to reaction type, and describes the advantages and limitations of the procedures. Traditional methods to speed up organic reactions involve energy-consuming processes and costly and environmentally "unfriendly" solvents. Additionally, isolation of the product requires energy and time-consuming purification processes. A simple solution, especially for reactions involving anionic reactants, is the use of phase-transfer catalysis. Quaternary ammonium cations have the ability to transfer the anionic reactants as non-solvated ion-pairs from aqueous media into organic media. The resultant effect is to increase the rate of the organic reaction by enhancing the reactivity of the anionic species and increasing the encounter rate with the organic substrate. Side reactions are frequently eliminated so that the overall yield of the desired product is increased.Quaternary Ammonium Salts presents procedures for reducing reaction times and the need for extreme conditions, which are frequently encountered under standard reaction procedures.This is the only book to be published on quaternary ammonium salts. Best Synthetic Methods volumes allow the practicing synthetic chemist to choose between all the alternatives and assess their real advantages and limitations. Each volume of the series deals with a particular topic from a practical point of view, giving detailed examples and precise experimental directions and hints. With the emphasis on laboratory use, these volumes represent a comprehensive and practical guide to modern synthetic organic chemistry.

Book Description
Long gone are the days when synthetic publications included parallel preparative experiments to document reproducibility of the experimental protocols and when journals required such documentation. The new Proven Synthetic Methods Series addresses concerns to chemists regarding irreproducibility of synthetic protocols, lack of characterization data for new compounds, and inflated yields reported in many chemical communications—trends that have recently become a serious problem. Volume One of Carbohydrate Chemistry: Proven Synthetic Methods includes more detailed versions of protocols previously published for the synthesis of oligosaccharides, C-glycosyl compounds, sugar nucleotides, click chemistry, thioglycosides, and thioimidates, among others. The compilation of protocols covers both common and less frequently used synthetic methods as well as examples of syntheses of selected carbohydrate intermediates with general utility. The major focus of this book is devoted to the proper practice of state-of-the-art preparative procedures, including: References to the starting materials used, reaction setup, work-up and isolation of products, followed by identification and proof of purity of the final material General information regarding convenience of operation and comments on safety issues Versatile and practically useful methods that have not received deserved, long-lasting recognition or that are difficult to access from their primary sources Copies of 1D NMR spectra of compounds prepared, showing purity of materials readers can expect Exploring carbohydrate chemistry from the academic points of view, the Carbohydrate Chemistry: Proven Synthetic Methods Series provides a compendium of preparatively useful procedures checked by chemists from independent research groups.
