Book Description
Atropisomerism and Axial Chirality provides a global survey of the chemistry of axially chiral compounds including biaryls, heterobiaryls, non-biaryl atropisomers, allenes and spyrocyclic derivatives. From the perspective of a synthetic organic chemist, this book provides a unique compilation of the available methodologies for their synthesis, with emphasis on the most efficient and modern strategies, a review of the huge amount of practical applications in the field of asymmetric catalysis, either as transition metal ligands or as organocatalysts, and an overview of their occurrence as bioactive compounds and natural products.The first of its kind, this book serves as a general introduction and a practical reference to advanced chemistry students and researchers, while also offering creative ideas for further developments in the field.

Book Description
This work describes the essential aspects of enantioselective catalysis, with chapters organised by concept rather than by reaction type. Each concept is supported by examples to give the reader broad exposure to a wide range of catalysts, reactions and reaction mechanisms.

Book Description
A comprehensive overview of the use of NMR spectroscopy for chiral discrimination Discrimination of Chiral Compounds Using NMR Spectroscopy concisely covers the broad array of reagents that make it possible to determine the optical purity and assign the absolute configuration of many classes of compounds. It describes chiral NMR derivatizing agents, solvating agents, metal-based reagents, and liquid crystals and discusses the range and types of compounds for which they can be used for analysis. After an overview of chiral reagents and methodologies, this reference: * Includes comprehensive coverage of the chiral reagents that have been reported * Catalogs the range of compounds for which different reagents have been shown to be effective * Includes specialty categories such as liquid crystals, ionic liquids, and the formation of chiral aggregates from achiral building blocks that do not fit into the broader categories * Offers experimental strategies for using the reagents that are likely to improve the quality of the results This guide describes the various systems and their overall utility, but goes further to show the full scope of the field as a way of guiding investigations into the optimal chiral reagents for use in NMR spectroscopy. It's a practical reference for organic chemists in the pharmaceutical industry, academia, and other areas, NMR spectroscopists, and researchers involved in the isolation and structure determination of natural products.

Book Description
While working as a chromatographer in the pharmaceutical industry, it became apparent to the editor that there was a pressing need for a comprehensive reference text for analysts working on the resolution of enantiomers by liquid chromatography (LC). This need arises from the fact that, whereas previously it was very difficult to determine enantiomers by direct means, there is now a wide choice of direct LC methods. At the same time, regulatory authorities have been changing their attitudes towards the administration of pharmaceuticals as racemates, partly because it is now possible to study the individual enantiomers. Clearly this abundance of new information needs to be rationalized. More importantly, the chiral LC systems which are commercially available or readily accessible to the practising chromatographer needed to be reviewed and, to a much greater extent than in existing reviews or books, discussed in terms of their practical application. Accordingly this book is very much orientated towards the practical aspects of these commercially available and readily accessible chiral LC systems. To this end, it is written for practising chromatographers by a team of practising, experienced chromatographers who have spent many years tackling the problems presented by resolving enantiomers by LC. The practical aspects of common chiral LC systems cannot be fully understood if discussed in isolation.

Book Description
In spite of important advances in asymmetric synthesis, chiral compounds cannot all be obtained in a pure state by asymmetric synthesis. As a result, enantiomer separation remains an important technique for obtaining optically active materials. Although asymmetric synthesis is a once-only procedure, an enantiomer separation process can be repeated until the optically pure sample is obtained. This book discusses several new enantiomer separation methods using modern techniques developed by experts in the field. These methods consist mainly of the following three types: 1) Enantiomer separation by inclusion complexation with a chiral host compound 2) Enantiomer separation using biological methods 3) Enantiomer separation by HPLC chromatography using a column containing a chiral stationary phase. Separation of a racemic compound has been called “optical resolution” or simply “resolution”. Nowadays, the descriptions “enantiomer resolution” or “enantiomer separation” are also commonly used. Accordingly, “Enantiomer Separation” is used in the title of this book. The editor and all chapter contributors hope that this book is helpful for scientists and engineers working in this field.
