Book Description
Written by a "who is who" of leading organic chemists, this anniversary volume represent the Organic Reactions editors' choice of the most important, ground-breaking and versatile reactions in current organic synthesis. The 15 reaction types selected for this volume include reactions for carbon-carbon bond formation, cross-coupling reactions, hydro- and halofunctionalizations, among many others. In line with the successful recipe of the series, each chapter is focused on a single reaction, discussing its mechanism and stereochemistry, scope and limitations, applications to synthesis, comparison with other methods, and experimental procedures. Each chapter concludes with a tabular survey of selected key application examples, complete with reported reaction conditions and yields, to serve as a quick reference guide for synthesis planning.

Book Description
The porphyrins are a class of naturally-occurring macrocycles and are ubiquitous in our world. As such, they have been called the Pigments of Life. This auspicious designation reflects their importance in numerous biological functions. Indeed, life as we understand it relies on the full range of biological processes that are either performed by or catalyzed by porphyrin-containing proteins. Chlorophyll-containing photosynthetic reaction centers in plants, for instance, convert light energy into chemical energy while producing oxygen along the way. It is this oxygen, evolved from photosynthesis, that is transported, stored, and reduced by heme-containing proteins in many organisms, including mammals. Not surprisingly, therefore, these molecules remain of fundamental interest to chemists and biochemists. Indeed, they continue to be intensely investigated by researchers world-wide.Inspired by the importance of the porphyrins, a new research direction has emerged in recent years that is devoted to the preparation and study of non-porphyrin polypyrrole macrocycles. Here, the principal objectives have been to generate completely synthetic systems that bear some structural resemblance to naturally-occurring porphyrin derivatives while being quite different in their specific chemical makeup. Within this context, three different research directions have evolved, namely those involving the syntheses of contracted, isomeric, and expanded porphyrins, respectively. It is the chemistry of these systems that is the subject of this book. Because of the newness of the field, the emphasis of this book will be on synthesis and characterization (all work on porphyrin isomers and much of that associated with expanded porphyrins has only appeared in the last 10 years). One chapter on applications has, however, been included. Also, in the context of the preparative portions of the text, some efforts have been made to explain why various porphyrin analogue targets are of interest.

Book Description
Allylic boron compounds have gained a prominent position as a truly practical class of synthetic reagents in the past twenty-five years. Their main application as a method for the stereoselective synthesis of homoallylic alcohols by allyl-transfer to carbonyl compounds is essentially unmatched. In this process, a new carbon-carbon bond is formed, and up to two new stereogenic centers are created in a predictably controlled manner. Highly effective and general enantioselective variants are available, with countless applications in the total syntheses of polyacetate and polypropionate natural products. Furthermore, the residual allylic unit can be manipulated through a number of different transformations such as oxidative cleavage, olefin metathesis, hydrometalations, and many others. The discovery of Lewis and Brønsted acid catalyzed manifolds recently, has opened new doors for further development of this important reaction. This book provides an up-to-date, comprehensive survey of the literature of this rich chemistry as it pertains to organic synthesis. Consistent with the goal of Organic Reactions, the content and presentation emphasize the preparative aspects of the reactions, giving considerable attention to the scope and limitations of the individual transformations along with detailed experimental procedures. A tabular survey of all examples of carbonyl allylboration used in organic synthesis is presented in nine tables organized by type of allylic boron reagent with listings within each table according to increasing carbon number of the carbonyl substrates. The literature is covered through December 2010, including a new listing of nearly 200 literature citations that supplement the original coverage of 834 references used in the earlier hard cover version of the chapter. Allylboration of Carbonyl Compounds is intended to be a useful, easily read reference book for all practitioners of synthetic organic chemistry working in academic and industrial laboratories.

Book Description
Organic Chemistry: Structure, Mechanism, Synthesis, Second Edition, provides basic principles of this fascinating and challenging science, which lies at the interface of physical and biological sciences. Offering accessible language and engaging examples and illustrations, this valuable introduction for the in-depth chemistry course engages students and gives future and new scientists a new approach to understanding, rather than merely memorizing the key concepts underpinning this fundamental area. The book builds in a logical way from chemical bonding to resulting molecular structures, to the corresponding physical, chemical and biological properties of those molecules. The book explores how molecular structure determines reaction mechanisms, from the smallest to the largest molecules—which in turn determine strategies for organic synthesis. The book then describes the synthetic principles which extend to every aspect of synthesis, from drug design to the methods cells employ to synthesize the molecules of which they are made. These relationships form a continuous narrative throughout the book, in which principles logically evolve from one to the next, from the simplest to the most complex examples, with abundant connections between the theory and applications. Featuring in-book solutions and instructor PowerPoint slides, this Second Edition offers an updated and improved option for students in the two-semester course and for scientists who require a high quality introduction or refresher in the subject. - Offers improvements for the two-semester course sequence and valuable updates including two new chapters on lipids and nucleic acids - Features biochemistry and biological examples highlighted throughout the book, making the information relevant and engaging to readers of all backgrounds and interests - Includes a valuable and highly-praised chapter on organometallic chemistry not found in other standard references
