The explosive growth of organoselenium chemistry over the past 12 years can be attributed to the specific properties of organic selenium molecules, which fit the requirements of modern organic synthesis. Most of them are well adapted to chemo-, regio- and stereo-selectivities. In addition, they can be used in mild experimental conditions which are compatible with the stability of both substrates and products in the preparation of unsaturated and functional complex molecules, especially in the field of natural products. This book describes and illustrates different synthetic routes to organic structures using selenium reagents or intermediates. The approach emphasizes that such transformations are simple, efficient and often carried out at room temperature. The scope ranges from the preparation of both inorganic and organic selenium reagents, through descriptions of structure, toxicity, biological aspects and nuclear magnetic resonance, to applications of specific selenium compounds in various syntheses including natural products and biologically active compounds.

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.

Selenium-based methods in synthetic chemistry have developed rapidly over the past years and are now offering highly useful tools for organic synthesis. Filling the gap for a comprehensive handbook and ready reference, this book covers all modern developments within the field, including biochemical aspects. The chemistry chapters are organized according to the different reactivities of various selenium compounds and reagents, with each chapter dealing with a special reaction type. Also includes a table with 77Se NMR shifts to aid in practical problems. From the Contents: * Electrophilic and Nucleophilic Selenium * Selenium Compounds in Radical Reactions * Selenium-Stabilized Carbanions * Selenium Compounds with Valency Higher than Two * Selenocarbonyls * Selenoxide Elimination and [2,3]-Sigmatropic Rearrangement * Selenium Compounds as Ligands and Catalysts * Biological and Biochemical Aspects of Selenium Compounds

The use of organoselenium reagents as catalysts is a common thread that runs through the chapters of this book, introducing important aspects of the modern organoselenium chemistry: organocatalysis, green chemistry, bioinspiration, antioxidant activity. The eBook covers the most recent developments in the classical synthetic application of organoselenium reagents such as electrophilic, nucleophilic and free radical reagents. The volume also features a discussion on the synthesis and the synthetic applications of some emerging classes of selenium compounds such as hypervalent selenium species and selenoamides, and also addresses some biological aspects such as the antimicrobial activity of organoselenium derivatives and the biochemistry of selenoproteins. A number of eminent scientists from different research groups were involved in the preparation of the 13 chapters of the book, making Organoselenium Chemistry: Between Synthesis and Biochemistry an excellent reference about selenium chemistry for researchers and graduate students in the field of selenium chemistry.

During the last fifteen years organoselenium chemistry underwent a spectacular mutation: from an exotic area of science practised by a few specialists it became a relatively well mastered and widely used methodology of synthetic organic chemistry. The key to this success is that a fair number of selenium based reagents and reactions have been discovered, which are able to perform specific transformations selectively and often under very mild conditions. The aim of this volume is to present the different selenium containing reagents now available to chemists, to mention the scope as well as the limitations of their reactions, and to compare those which possess similar reactivities. The authors present the reagents in the order of increasing oxidation level around the selenium atom.

This book is about the recognition of new principles in Organic Chemistry. It is also about the discovery and invention of Chemical Reactions. In addition, it deals with the determination of structure by chemical degradation during the epoch when physical methods were not well developed. Also presented are new reagents and new types of functional groups never seen in chemistry before. The overall aim of the collected papers is to show how thought can direct original research and to demonstrate how thought about old or new chemical facts can lead to originality. This is further illuminated by commentaries which Prof Barton has written to accompany these papers.

The individual chapters in this volume cover the scope and impact of main group organometallic compounds and reagents on organic synthesis during the last ten to fifteen years. In a number of chapters, topics are dealt with in detail that either were not covered at all in COMC (eg selenium, tellurium) or were given scant attention (eg oxymercuration, organoantimony compounds). Certain topics, like directed metallation and LiKOR bases have only achieved prominence in synthesis in the last ten years, and are now reviewed by leading experts.
