Download or read book More Dead Ends and Detours written by Miguel A. Sierra and published by John Wiley & Sons. This book was released on 2013-07-11 with total page 297 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: In Volume 18 of this well-established series, Professor Atta-ur-Rahman again brings together the work of several of the world's leading authorities in organic chemistry. Their contributions demonstrate the rapid, ongoing development of this field by illustrating many of the latest advances in synthetic methods, total synthesis, structure determination, biosynthetic pathways, and biological activity.The opening chapter presents an overview of strategies for the synthesis of several classes of natural products with an emphasis on complex polycyclic systems. Subsequent chapters discuss the synthesis of specific classes of compounds, including morphine, polyketides, acetogenins, nonactic acid derivatives, complex spirocyclic ethers, ä-lactam and pyridone derivatives, inositol phosphates, sphingolipids, brassinosteroids, Hernandia lignans, and dimeric steroidal pyrazine alkaloids. Finally, the ever stronger links between chemistry and biology are reinforced by chapters on the origin and function of secondary metabolites, bioactive conformations of gastrin hormones, and immunochemistry.

Download or read book Retrosynthetic Analysis and Synthesis of Natural Products 1 written by Olivier Piva and published by John Wiley & Sons. This book was released on 2019-09-24 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: For chemists, attempting to mimic nature by synthesizing complex natural products from raw material is a challenge that is fraught with pitfalls. To tackle this unique but potentially rewarding task, researchers can rely on well-established reactions and methods of practice, or apply their own synthesis methods to verify their potential. Whatever the goal and its complexity, there are multiple ways of achieving it. We must now establish a strategic and effective plan that requires the minimum number of steps, but lends itself to widespread use. This book is structured around the study of a dozen target products (butyrolactone, macrolide, indole compound, cyclobutanic terpene, spiro- and polycyclic derivatives, etc.). For each product, the different disconnections are presented and the associated syntheses are analyzed step by step. The key reactions are described explicitly, followed by diagrams showing the range of impact of certain transformations. This set of data alone is conducive to understanding syntheses and indulging in this difficult, but worthwhile activity.

Download or read book Total Synthesis of Plakortide E and Biomimetic Synthesis of Plakortone B written by Xiao-Yu Sun and published by Springer Science & Business Media. This book was released on 2012-01-15 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his thesis, Xiaoyu Sun conducts the first total synthesis of all possible stereoisomers of plakortide E and also confirms the absolute configuration of natural plakortide E. Xiaoyu Sun subsequently converts Plakortide E methyl ester to plakortone B in a biomimetic conversion. Construction and functionalization of cyclic peroxides are notoriously difficult due to the very low O-O bond dissociation energy. Plaktoride E is isolated from the Jamaican marine sponge platorits halichondrioides and contains a five-membered peroxide ring, with oxygen atoms linked to tertiary C4 and C6 centers. The methodology used for synthesizing highly substituted cyclic peroxides is novel and useful, and not only extends the field of Pd-catalyzed reactions, but also provides a convenient synthetic approach for the preparation of the 1,2-dioxolanes series. Plakortide E and plakortone B are bioactive, which means that the synthetic studies on them and their analogs are pivotal in drug discovery.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the author describes the total synthesis of natural product Maoecrystal V in detail. In the first part of the thesis, the author introduces the research background and reviews the research progress in total synthesis of Maoecrystal V. In the second part, the author develops a novel and concise approach for the stereo selective construction of the tetracyclic model system of Maoecrystal V. The model system is accomplished in 8 steps with 20% yield. In the third part, the author describes the first successful total synthesis of Maoecrystal V and investigates four strategies for constructing the key tetrahydrofuran oxa-bridge skeleton. The total synthesis starts from a known compound and is accomplished in 17 steps with 1.2% yield. The successful total synthesis of Maoecrystal V will contribute to the development of efficient synthetic strategies for natural products and other compounds with complex structures.

Download or read book Organic Synthesis Via Examination of Selected Natural Products written by David J. Hart and published by World Scientific. This book was released on 2011 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complete with problems and solutions, this book is written for advanced graduate and undergraduate students to expose them to a variety of strategies for the synthesis of organic compounds. This is done largely within the context of natural products synthesis, but includes some unnatural products synthesis. Multiple approaches to each group of synthesis targets are presented, and the approaches are compared with one another with an eye on similarities and differences. General problems in organic synthesis (for example, strategies for the preparation of 6-membered rings and 5-membered rings, the importance of oxidation state, the problem of acyclic diastereoselectivity, the problem of controlling absolute stereochemistry, the importance of functional group relationships) are introduced early in the book and revisited throughout the text within the context of a variety of structurally unrelated natural products. The book includes power-point presentations to provide teachers who do not (or do) specialize in organic synthesis with access to well-organized material they can use in the classroom (with advanced students). The book provides the reader with a somewhat historical overview of organic and natural products chemistry, and spans synthetic methodology that dates from the 1940's to present time. It is written in a style that readers will find entertaining at times. It also contains lots of useful references with complete titles provided. This is much more helpful to the reader than the usual author-journal-year-page information.
