Download or read book Organic Synthesis using Samarium Diiodide written by David J Procter and published by Royal Society of Chemistry. This book was released on 2009-11-10 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Samarium diiodide is one of the most important reducing agents available to synthetic organic chemists. The lanthanide(II) reagent acts by single-electron transfer to organic substrates leading to the formation of both radical and/or anionic intermediates. The power of the reagent arises from its versatility - samarium diiodide can be used in processes ranging from functional group conversions to elaborate carbon-carbon bond-forming cyclization sequences that result in a dramatic increase in molecular complexity. In addition, reactions involving samarium diiodide often show high stereoselectivity as samarium ions can coordinate to Lewis basic sites on substrates and can direct the stereochemical course of reactions. The ability to fine-tune the reactivity of the reagent by the use of additives and co-solvents is an additional, attractive feature. Although samarium diiodide is used extensively by organic chemists, there is still a widely held view that the reagent can be difficult to prepare and use. In addition, samarium diiodide can mediate such a wide variety of organic chemistry that potential new users are often overawed by the extensive primary literature on the reagent. The objective of this book is to provide a concise, practical guide to the reagent. Rather than being a comprehensive review of the chemistry of samarium diiodide, this user-friendly book adopts an "an all you need to know" approach to the topic. The international authors are well-known for their work with the reagent and their expertise covers current developments in new reactivity and selectivity, applications in target synthesis, co-solvent and additive effects, coordination chemistry and mechanism. The book includes the best methods for preparing and handling the reagent, how solvents, co-solvents and additives alter reactivity, the basic mechanisms of reactions, common transformations using the reagent, and emerging areas in samarium diiodide chemistry. The authors have distilled the extensive primary literature to allow the reader to quickly grasp an understanding of the reagent and its utility. The illustrative practical procedures help the reader to prepare and use the reagent in the laboratory while references from the recent literature allow readers to pursue their interest in the popular reagent. The book also contains many illustrations and chemical schemes.

Available in PDF, EPUB and Kindle. Book excerpt: Englerin A is a guaiane sesquiterpene with potent and selective growth inhibition activity against six human renal cancer cell lines. Englerin A has captured the attention of the synthetic organic chemistry community owing to its exciting activity and its attractive polycyclic and functionalized structure. This document describes the process by which we developed a carbonyl-based synthesis of the natural product that relies upon simple, inexpensive starting materials. Utilizing a diastereoselective Michael addition reaction, followed by a remarkably selective samarium-mediated carbonyl-alkene cyclization, we completed an eight-step synthesis of englerin A.

Download or read book Linker Strategies in Solid-Phase Organic Synthesis written by Peter Scott and published by John Wiley & Sons. This book was released on 2009-10-13 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linker design is an expanding field with an exciting future in state-of-the-art organic synthesis. Ever-increasing numbers of ambitious solution phase reactions are being adapted for solid-phase organic chemistry and to accommodate them, large numbers of sophisticated linker units have been developed and are now routinely employed in solid-phase synthesis. Linker Strategies in Solid-Phase Organic Synthesis guides the reader through the evolution of linker units from their genesis in solid-supported peptide chemistry to the cutting edge diversity linker units that are defining a new era of solid phase synthesis. Individual linker classes are covered in easy to follow chapters written by international experts in their respective fields and offer a comprehensive guide to linker technology whilst simultaneously serving as a handbook of synthetic transformations now possible on solid supports. Topics include: the principles of solid phase organic synthesis electrophile and nucleophile cleavable linker units cyclative cleavage as a solid phase strategy photocleavable linker units safety-catch linker units enzyme cleavable linker units T1 and T2 –versatile triazene linker groups hydrazone linker units benzotriazole linker units phosphorus linker units sulfur linker units selenium and tellurium linker units sulfur, oxygen and selenium linker units cleaved by radical processes silicon and germanium linker units boron and stannane linker units bismuth linker units transition metal carbonyl linker units linkers releasing olefins or cycloolefins by ring-closing metathesis fluorous linker units solid-phase radiochemistry The book concludes with extensive linker selection tables, cataloguing the linker units described in this book according to the substrate liberated upon cleavage and conditions used to achieve such cleavage, enabling readers to choose the right linker unit for their synthesis. Linker Strategies in Solid-Phase Organic Synthesis is an essential guide to the diversity of linker units for organic chemists in academia and industry working in the broad areas of solid-phase organic synthesis and diversity oriented synthesis, medicinal chemists in the pharmaceutical industry who routinely employ solid-phase chemistry in the drug discovery business, and advanced undergraduates, postgraduates, and organic chemists with an interest in leading-edge developments in their field.

Available in PDF, EPUB and Kindle. Book excerpt: Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure-reactivity relationship of organic compounds. This textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success-rate. A must for every graduate student but also for every chemist in industry and academia.
