Dianion Chemistry in Organic Synthesis
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.
Concerted Organic and Bio-Organic Mechanisms
The concept of concerted mechanisms was formulated nearly 90 years ago and virtually all general organic chemistry texts mention it. Until now, however, no monograph has addressed the concept explicitly. Over the last two decades, substantial advancements made in the development of precise methods for elucidating concerted mechanisms have heightened the need for a comprehensive text on the subject. Concerted Organic and Bio-organic Mechanisms gathers the salient materials related to this emerging field into a single text. It sets forth the precise definition of concertedness-along with working sub-definitions-and describes rigorous experimental tools chemists can use to diagnose the existence or absence of concerted mechanisms. Advances in our understanding of concerted mechanisms lead to further questions. Concerted Organic and Bio-organic Mechanisms provides the background and the tools researchers need to consider these important questions and further advance the frontiers of reactions, synthesis, and catalysis.
Capillary Electrophoresis
The importance of capillary electrophoresis (CE) as an analytical tool has increased dramatically over the last ten years. It has changed from being an exploratory technique, mainly of academic interest, to one that is applied to solve "real" analytical problems. CE is easily adapted to its various modes of operation, often requiring little more than a change of the buffer solution, and is quickly becoming the preferred technique when analyzing minute amounts of available material. Featuring new chapters on CE analysis of inorganic ions and carbohydrates, the new edition of Capillary Electrophoresis not only presents this method as an academic tool, but also provides applications for solving...
Organozinc Reagents in Organic Synthesis
Organozinc reagents are used extensively in organic synthesis to find useful pathways to organic products. Illustrated and tabulated with over 950 equations, schemes, tables, and figures, Organozinc Reagents in Organic Synthesis provides an overall picture of the chemistry of organozinc compounds. Written by a professor of organic chemistry, the book familiarizes the reader with the reactions involving organozinc reagents that have general usefulness in synthesis. Emphasis is placed on preparation methods and reactivity of organozinc reagents. Reactions are summarized in equations and schemes, making it easy for you to see the characteristics of each type of reaction.
C-Glycoside Synthesis
This book examines methods particularly well suited for either a- or b-C-glycoside formation. It helps field workers quickly select the best method for synthesizing a particular type of C-glycoside. The use of C-glycosides as synthons in natural product synthesis is also addressed.
Lewis Acids and Selectivity in Organic Synthesis
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.
Asymmetric Synthetic Methodology
This comprehensive text presents a critical discussion of the scopes and limitations of various organic synthetic methodologies that are available for performing asymmetric transformations. In addition to purely chemical methods, the book covers applications of new enzymes and other biological systems that are increasingly useful in asymmetric methodology.
Mannich Bases-Chemistry and Uses
This book covers the remarkable development of the chemistry and applications of Mannich bases within the last 30 years. It provides an updated and comprehensive look at these compounds-compounds identified at the beginning of the century. Particular emphasis is placed on the versatile chemistry of Mannich bases. Synthesis and reactions of Mannich bases are systematically treated in the first two chapters, which include a thorough review of the most recent advances on the topic. Chapters 3 and 4 are devoted to the macromolecular chemistry and the chemistry of natural compounds, two emerging areas of application of the chemistry of Mannich bases. Chapter 5 deals with structure/property relationships that enable the production of tailor-made molecular structures suited to different practical applications. A survey of the main uses of individual Mannich bases according to the type of industrial branch is also reported.
Liposome Technology, Second Edition
Liposome Technology, Second Edition, is an updated, expanded new edition of a classic volume in the field. It covers all aspects of liposome technology, including liposome preparation and analysis, drug entrapment, and techniques used for in vivo and in vitro evaluation of liposomes. Leading authorities have contributed 70 chapters to create what is destined to be the standard liposome technology book for the 1990s. Many of the chapters describe methodologies practiced in authors' laboratories and provide specific examples of how these methodologies are applied in specific circumstances. Liposome Technology, Second Edition will be an essential reference volume for academic and industrial researchers in pharmacology, pharmacy, medicine, biochemistry, and immunology. What's new in the 2nd Edition? The 2nd Edition covers significant developments in liposome technology that have occurred since the publication of the 1st Edition in 1982. These developments include the following: New preparative procedures Special approaches to accommodate the incorporation of certain drugs New targeting techniques Large scale production of liposomes, patents, and clinical trials
Modern NMR Techniques for Synthetic Chemistry
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 particul...
