Available in PDF, EPUB and Kindle. Book excerpt: Success comes in many forms and in synthesis it can be a failure that results in their ultimate successful solutions. This long-awaited sequel to "Dead Ends and Detours" retains the proven concept while featuring over 20 new case studies of failed strategies and their (successful) solutions in natural product total synthesis. Additionally, computational models are used to discuss the problem in much more detail and to provide readers with additional information not found in the primary literature. The topics range from classic synthetic reactions (e.g. Diels Alder reaction), metal-mediated coupling reactions, metathesis, and asymmetric catalysis to the importance of protecting and activating groups. This book will benefit not only graduate students in organic chemistry but also advanced researchers as they gain knowledge derived from the step-by-step analysis of mistakes made in the past and, thus be able to improve their own chemical reaction planning. With its coverage of the most commonly applied reaction types, the book perfectly complements its predecessor, which focuses on general aspects, such as reactivity and selectivity.

Download or read book Elements of Synthesis Planning written by R. W. Hoffmann and published by Springer Science & Business Media. This book was released on 2009-01-07 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesis is at the core of organic chemistry. In order for compounds to be studied—be it as drugs, materials, or because of their physical properties— they have to be prepared, often in multistep synthetic sequences. Thus, the target compound is at the outset of synthesis planning. Synthesis involves creating the target compound from smaller, readily available building blocks. Immediately, questions arise: From which bui- ing blocks? In which sequence? By which reactions? Nature creates many highly complex “natural products” via reaction cascades, in which an asso- ment of starting compounds present within the cell is transformed by speci c (for each target structure) combinations of modular enzymes in speci c - quences into the target compounds [1, 2]. To mimic this ef ciency is the dream of an ideal synthesis [2]. However, we are at present so far from - alising such a “one-pot” operation that actual synthesis has to be achieved via a sequence of individual discrete steps. Thus, we are left with the task of planning each synthesis individually in an optimal fashion. Synthesis planning must be conducted with regard for certain speci - tions, some of which are due to the structure of the target molecule, and some of which relate to external parameters such as costs, environmental compatibility, or novelty. We will not consider these external aspects in this context. Planning of a synthesis is based on a pool of information regarding chemical reactions that can be executed reliably and in high chemical yield.

Available in PDF, EPUB and Kindle. Book excerpt: The past two decades have seen an explosion in research on the synthesis of sesquiterpenes, an important class of hydrocarbons commonly found in oils, resins, and balsams. Volume Eleven in The Total Synthesis of Natural Products series continues to review this dynamic area of chemistry. It features systematic, A-to-Z coverage of sesquiterpenes synthesized between 1979-1994-a sesquidecade. Focusing on bicyclic and tricyclic compounds in sesquiterpene synthesis, this authoritative work complements Volume Ten's coverage of acyclic and monocyclic sesquiterpenes. The authors comb through the hundreds of sesquiterpene syntheses already developed, consolidating the multitude of research papers, and providing extensive references as well as author and subject indexes. To keep the presentation manageable, they emphasize literature where natural products were prepared, leaving out natural ring systems or compounds whose structures were misassigned. This volume presents multiple syntheses of the same compound in chronological order, making the various steps of the synthetic strategy easily accessible. In addition, it addresses one of the most important developments in sesquiterpene research, namely the increase in compound targets prepared in an optically active form. And while syntheses of racemates are not specifically marked, legends for synthesis schemes producing optically active compounds include their absolute configurations, signs of optical rotation, or both. An important resource for organic chemists, pharmaceutical and medicinal chemists, natural prod-ucts chemists, and biochemists, The Total Synthesis of Natural Products offers valuable insight into the structure and makeup of sesquiterpenes while serving as a practical tool for locating any of the major classes of sesquiterpene compounds. An invaluable guide for the chemist interested in natural products. Providing a fascinating, comprehensive look at sesquiterpene synthesis, Volume Eleven of The Total Synthesis of Natural Products reviews sesquiterpenes synthesized in the period 1979-1994, continuing the coverage begun with Volume Ten in the series (see below). This authoritative work: Focuses on bicyclic and tricyclic sesquiterpenes. Explains the structure and makeup of this important class of hydrocarbons. Serves as a useful, practical tool for researchers interested in locating any of the major classes of sesquiterpene compounds. Provides multiple syntheses of the same compound chronologically, clearly showing the evolution of the synthetic strategy. Also available . . .THE TOTAL SYNTHESIS OF NATURAL PRODUCTS Volume Ten, Edited by David Goldsmith. A complement to this work, Volume Ten examines compounds with acyclic and monocyclic ring structures in sesquiterpene synthesis. 1997 (0-471-59679-5) 173 pp.

Download or read book The Total Synthesis of Natural Products Volume 5 written by John ApSimon and published by John Wiley & Sons. This book was released on 2009-09-22 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each volume reviews the total synthesis of a set of compounds looking at syntheses reported historically and at the practice current at the time of publication. From volume 1 focusing on carbohydrates, prostagladins, nucleic acids, antibiotics, naturally occurring oxygen ring compounds and pyrrole pigments, the series continues with coverage of aromatic steroids, monoterpenes, triterpenes, sesquiterpenes, cannabinoids, natural inophores, insect pheromones and alkaloids. Volumes revisit the total synthesis of key compounds such as carbohydrates, nucleic acids and pyrrole pigments several times during the series building a picture of the historic development of total synthesis techniques for these major groups. Chapters are edited by experts in their field to give a complete overview of the best in the field at the time.

Download or read book Organic Syntheses by Oxidation with Metal Compounds written by W.J. Mijs and published by Springer. This book was released on 2014-03-12 with total page 908 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with the synthetic aspects of oxidation reactions involving metal compounds. which are readily available or easy to prepare. The sequence followed in the chapters is as follows: a general introduction. a limited treatment of reaction mechanisms to serve as a basis for synthesis. and scope and limitations of the oxidant system. mostly in terms of substrate and product classes. Finally, at the end of each chapter. representative synthetic procedures are given together with relevant experimental considerations. A general table is included as an appendix. This contains substrate classes and resulting product classes, referring to the oxidative procedures in the chapters. The table provides the synthetic organic chemist with a quick overview of oxidation possibilities with metal-contain ing oxidants, enabling him to select the right method for his purpose. The editors hope that not only organic research chemists in industry and at universities, but also advanced undergraduate and graduate students in organic chemistry, will find this book a useful guide in the design, understanding, and practical performance of oxidative organic syntheses. The editors are grateful to the authors not only for their contributions. containing interesting new developments in oxidation chemistry, but also for the way they fitted the text into the general framework given for the book. Their suggestions and comments are gratefully acknowledged. Thanks are also due to Mrs. A. I. Rohnstrom-Ouwejan, secretary to the editors, for her administrative support.
