Book Description
Many laboratories were reluctant at first to embrace dianion chemistry as part of the standard reaction repertoire. Today, however, researchers can comfortably draw upon the dianion literature to choose an abundance of reagents and strategies that are reliable, effective, and, in many cases, the best answer to a synthetic problem. This interesting book introduces, surveys, and consolidates carbon-based dianion chemistry. Chapter 1 serves as an introduction and as an index of the various dianions covered in the book. Chapters 2 through 5 cover the ensemble of dianion types designated by their first deprotonation site. Each chapter contains an experimental section that explains relevant protocols.

Book Description
More than any other branch of organic chemistry, synthesis has improved our understanding of the structure, dynamics, and transition of molecules. The availability of sophisticated tools and new techniques has made organic synthesis more challenging than ever for those in the field. This updated edition of the 1970 work highlights significant and intriguing synthetic achievements: their ingenuity in design, extent of stereochemical control, new reactions, and new reagents. Approximately 100 examples illustrate various aspects of organic synthesis, with particular emphasis on bond-making and bond-breaking, dissymetry, conformation, and stereoelectric considerations. Each describes the synthesis of a natural product or of an unusual or strained molecule. Numerous flow sheets and perspective structural formulas illustrate the force of arguments predicting the stereochemical outcome of important steps. Also included is a type-transformation index which highlights some less common reactions.

Book Description
Lewis acids provide inexpensive access to elaborated molecules obtained with high selectivities (regio-, stereo-, and enantioselectivity). Lewis Acids and Selectivity in Organic Synthesis is the first book to deal with these new and promising roles of Lewis acids. The book begins with general considerations on Lewis acids and a description of Lewis acid-carbonyl complexes, which are involved in most of the reactions described: ene reactions, allylsilane and allyltin addition to carbonyl compounds, addition of nucleophiles to acetals, conjugated addition of allylsilanes and allyltins to unsaturated carbonyl compounds (Sakurai reaction), and Diels-Alder reaction. Subsequent chapters examine these issue in detail, with special attention given to the way Lewis acids induce diastereo- and enantioselectivity. The extensive use of schemes (approximately 1000) ensures rapid visual uptake of the information. Lewis Acids and Selectivity in Organic Synthesis serves as a valuable source of information for all who face the challenge of selectivity in organic synthesis.

Book Description
Organic chemists working on the synthesis of natural products have long found a special challenge in the preparation of peptides and proteins. However, more reliable, more efficient synthetic preparation methods have been developed in recent years. This reference evaluates the most important synthesis methods available today, and also considers methods that show promise for future applications. This text describes the state of the art in efficient synthetic methods for the synthesis of both natural and artificial large peptide and protein molecules. Subjects include an introduction to basic topics, linear solid-phase synthesis of peptides, peptide synthesis in solution, convergent solid-phase synthesis, methods for the synthesis of branched peptides, formation of disulfide bridges, and more. The book emphasizes strategies and tactics that must be considered for the successful synthesis of peptides.

Book Description
Over the last twenty years the use of sulphones in organic synthesis has increased dramatically, the synthetic repertoire of sulphones having been developed to such an extent as to rival the carbonyl functionality for versatility. Not only have sulphones been employed in a great many synthetic methodologies, enabling the preparation of a vast array of functionalised products, but the sulphone group has also proved to be of enormous value in many of the most demanding and sophisticated total syntheses carried out in recent years. This book describes in detail all of the important sulphone chemistry employed in organic synthesis, ranging from the well-established sulphone-mediated methods to less familiar sulphone reactions and very recent discoveries of synthetic potential.

Book Description
A blend of theory and practical advice, Modern NMR Techniques for Synthetic Chemistry illustrates how NMR spectroscopy can be used to determine the abundance, size, shape, and function of organic molecules. It provides you with a description the NMR technique used (more pictorial than mathematical), indicating the most common pulse sequences, some practical information as appropriate, followed by illustrative examples. This format is followed for each chapter so you can skip the more theoretical details if the practical aspects are what interest you. Following a discussion of basic parameters, the book describes the utility of NMR in detecting and quantifying dynamic processes, with particular emphasis on the usefulness of saturation-transfer (STD) techniques. It details pulsed–field gradient approaches to diffusion measurement, diffusion models, and approaches to ‘inorganic’ nuclei detection, important as many synthetic pathways to new organics involve heavier elements. The text concludes with coverage of applications of NMR to the analysis of complex mixtures, natural products, carbohydrates, and nucleic acids—all areas of activity for researchers working at the chemistry-life sciences interface. The book’s unique format provides some theoretical insight into the NMR technique used, indicating the most common pulse sequences. The book draws upon several NMR methods that are resurging or currently hot in the field and indicates the specific pulse sequence used by various spectrometer manufacturers for each technique. It examines the analysis of complex mixtures, a feature not found in most books on this topic.
