This book was released on 2007-04-13 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Stereo-Differentiating Reactions: The Nature of Asymmetric Reactions provides an introduction to asymmetric reactions. It brings together synthetic organic chemistry, stereochemistry, group theory, the theory of optical rotation, experimental methods, etc., all of which are basic to the study of stereo-differentiating reactions, to form a unified approach based on the new concept of "differentiation." The authors hope that the value of the new concept, which is rather more complex than conventional treatments of asymmetric reactions, will become clear in the present book. This new concept should be useful in many fields of study, not only the development of stereo-differentiating reactions, but also in the study of general reaction mechanisms in organic chemistry. The book contains nine chapters and begins with a historical background of studies on asymmetric reactions. This is followed by separate chapters on molecular symmetry and chirality; nomenclature for chirality, prochirality, and stereo-differentiating reactions; the mechanisms of stereo-differentiating reactions; methods for studying stereo-differentiating reactions; and the basic principle of optical activity.

This book was released on 2013 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time the full multinuclear 1H, 13C, and 19F assignments were established for 4-amino-1,1,2,2,9,9,10,10-octafluoro[2.2]paracyclophane (OFP-NH2). These were achieved by using a combination of 1D, COSY, and HETCOR NMR techniques. The assignments were later confirmed by nOe experiments. The interaction of OFP-NH2 with different chiral shift reagents was explored, and it was shown that it is possible to clearly detect both enantiomers of the planar chiral OFP-NH2 (in both the 1H and 19F NMR). This method of chiral discrimination was also shown to be applicable to other similar chiral OFP derivatives.

Book excerpt: Synthesized tris[d,d-dicampholylmethanato]europium(III), Eu(dcm)3, and three other commercially available chiral lanthanide shift reagents are used to resolve the nuclear magnetic resonance (NMR) spectra of the enantiomeric N-CH3 and C-CH3 protons in d- and l-methamphetamine. The chemical shift difference between the corresponding enantiomeric protons induced by these four shift reagents are compared and evaluated in their prospective use for enantiomeric identification and determination. It is concluded that while the chemical shift difference between the two enantiomerie C-CH3 protons induced by Eu(dcm)3 is most suitable for qualitative identification of these enantiomers, the NMR spectra of the N-CH3 protons are best resolved by Eu(dcm)3 and most suitable for quantitative determinations.

Available in PDF, EPUB and Kindle. Book excerpt: Divided into the three main sections of synthesis, analysis and drug development, this handbook covers all stages of the drug development process, including large-scale synthesis and purification of chirally pure pharmaceuticals. The two editors from academia and a major pharmaceutical company have assembled an experienced, international team who provide first-hand practical advice and report previously unpublished data. In the first section, the isolation of chiral drugs from natural sources, their production in enzymatic processes and the resolution of racemic mixtures in preparative chromatography are outlined in separate chapters. For the section on qualitative and quantitative analysis, enantioselective chromatographic methods are presented as well as optical methods and CE-MS, while the final section deals with the pharmacology, pharmacokinetics and metabolic aspects of chiral drugs, devoting whole chapters to stereoselective drug binding and modeling chiral drug-receptor interactions. With its unique industry-relevant aspects, this is a must for medicinal and pharmaceutical chemists.

Available in PDF, EPUB and Kindle. Book excerpt: This text is aimed at people who have some familiarity with high-resolution NMR and who wish to deepen their understanding of how NMR experiments actually ‘work’. This revised and updated edition takes the same approach as the highly-acclaimed first edition. The text concentrates on the description of commonly-used experiments and explains in detail the theory behind how such experiments work. The quantum mechanical tools needed to analyse pulse sequences are introduced set by step, but the approach is relatively informal with the emphasis on obtaining a good understanding of how the experiments actually work. The use of two-colour printing and a new larger format improves the readability of the text. In addition, a number of new topics have been introduced: How product operators can be extended to describe experiments in AX2 and AX3 spin systems, thus making it possible to discuss the important APT, INEPT and DEPT experiments often used in carbon-13 NMR. Spin system analysis i.e. how shifts and couplings can be extracted from strongly-coupled (second-order) spectra. How the presence of chemically equivalent spins leads to spectral features which are somewhat unusual and possibly misleading, even at high magnetic fields. A discussion of chemical exchange effects has been introduced in order to help with the explanation of transverse relaxation. The double-quantum spectroscopy of a three-spin system is now considered in more detail. Reviews of the First Edition “For anyone wishing to know what really goes on in their NMR experiments, I would highly recommend this book” – Chemistry World “...I warmly recommend for budding NMR spectroscopists, or others who wish to deepen their understanding of elementary NMR theory or theoretical tools” – Magnetic Resonance in Chemistry
