Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. The treatment emphasizes unifying principles, showing how common mechanisms link seemingly disparate reactions. Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and "common error alerts" are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set. The author has drawn on his own research and the current literature to ensure that appropriate attention is given to topics across the range of modern organic chemistry. The text is unique in its inclusion of a chapter on reactions mediated or catalyzed by transition metals, an area in which mechanistic understanding is now essential. Relatively new topics such as olefin metathesis and cycloaromatization are covered without giving short shrift to more traditional areas such as carbonyl chemistry. The text assumes a basic knowledge of organic chemistry. It can be used either in a formal course or by students working on their own, and will be particularly useful for graduate students studying for qualifying examinations. It will also be useful to students and researchers in biochemistry, pharmacology, and inorganic chemistry. This is an excellent and well-presented work.... The author ... has succeeded well in treating the central ideas of reactivity and selectivity in an integrated whole. The clear style of writing, the well chosen examples, and the ... concise summaries of the main points provided at the end of each chapter should enable the reader to easily consolidate what has been learned.... The book is indeed a little work of art. ¿ Jens Hartung, Angewandte Chemie International Edition I have taught a one-credit course with this book for three years, and, uniformly, the students have rated this book highly for its clarity and for the scope of the problems. ... This book does an excellent job at its stated goal: "to teach students to come up with reasonable mechanisms for reactions they have never seen before." ¿ Amy Howell, Synthesis I have just finished my first year of graduate studies in organic chemistry at Duke University. I just wanted to let you know how much your book got me through the past year of course work.... When it came to mechanisms, I found the clarity and thoroughness I needed only in your book. It was impressive how you were able to present so much information in a clear and comprehensive manner yet keep the book so manageable in size. In addition to the text, I also was able to benefit from the problems.... Great practice!! The on-line answers are much better than looking up answers by reference.... I am reading it again this summer in preparation for my preliminary exam next spring. ¿ David Gooden

As pharmaceutical companies look to develop single enantiomers as drug candidates, chemists are increasingly faced with the problems associated with this subclass of organic synthesis. "The Handbook of Chiral Chemicals, Second Edition" highlights the problems associated with the production of chiral compounds on a commercial scale. The handbook first elaborates upon starting materials obtained from a 'chiral pool', which can be derived from natural products. Then it explains methods and reactions that can introduce or influence stereogenic centers, particularly asymmetric hydrogenations, oxidations, pericyclic reactions, and enzymatic methods.While hydrogenations have been the most widely employed approach for the large-scale synthesis of several commercial compounds, the search for the ideal catalyst has consistently led researchers to enzymes present in biological systems. Several chapters concentrate on understanding how to manipulate enzymes for catalyzing new reactions for taking new substrates. Other significant topics include chiral auxiliaries, chromatographic techniques, enantiomers-specific reactions, and resolution. This second edition updates all its chapters, illustrating the speed of development in this field, and features new chapters that highlight successful approaches in an industrial setting. "The Handbook of Chiral Chemicals, Second Edition" is a guide to advances in the field that result in more efficient and cost-effective synthesis of chiral chemicals.

Modified Cyclodextrins for Chiral Separation offers a review of the latest advances in developing modified cyclodextrins as chiral selectors for various chromatographic and electromigration techniques. Over the years, many descriptions of chiral separation have appeared in academic journals and books, but most of them have been devoted to either the development of analytical methods and protocols or the summary of different chiral selectors, including cyclodextrins for chiral separation applications. This is in marked contrast to this volume which focuses on the research endeavors concerning the development of cyclodextrin derivatives specifically as either chiral mobile phases for capillary electrophoresis, or chiral stationary phases for various chromatographic techniques including gas chromatography, or high-performance liquid chromatography and supercritical fluid chromatography. The ongoing thread in this book is the synthesis of structurally-defined cyclodextrin derivatives and their applications in enantiomer separation by means of different analytical techniques. Modified Cyclodextrins for Chiral Separation is intended for those who are interested in expanding their knowledge of cyclodextrin chemistry and chiral separation, and in what cyclodextrin modification can be made to suit the needs of chiral selectors for different analytical techniques. It primarily focuses on the state-of-the-art cyclodextrin chemistry which is the basis for all chiral selectors used in these chiral separation techniques.

Stimulated by the increasing importance of chiral molecules as pharmaceuticals and the need for enantiomerically pure drugs, techniques in chiral chemistry have been expanded and refined, especially in the areas of chromatography, asymmetric synthesis, and spectroscopic methods for chiral molecule structural characterization. In addition to synthetic chiral molecules, naturally occurring molecules, which are invariably chiral and generally enantiomerically enriched, are of potential interest as leads for new drugs. VCD Spectroscopy for Organic Chemists discusses the applications of vibrational circular dichroism (VCD) spectroscopy to the structural characterization of chiral organic molecules. The book provides all of the information about VCD spectroscopy that an organic chemist needs in order to make use of the technique. The authors, experts responsible for much of the existing literature in this field, discuss the experimental measurement of VCD and the theoretical prediction of VCD. In addition, they evaluate the advantages and limitations of the technique in determining molecular structure. Given the availability of commercial VCD instrumentation and quantum chemistry software, it became possible in the late 1990s for chemists to use VCD in elucidating the stereochemistries of chiral organic molecules. This book helps organic chemists become more aware of the utility of VCD spectroscopy and provides them with sufficient knowledge to incorporate the technique into their own research.
