Download or read book Silver in Organic Chemistry written by Michael Harmata and published by John Wiley & Sons. This book was released on 2011-01-11 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first authoritative book on using silver cations in organic chemistry—for catalysis and more! With more sophisticated catalytic methodologies fueling a resurgence in the study of cation-based chemistry, gold and platinum have stepped to the fore as the unique agents used to create new chemical reactions. Although these metals have become a primary focus of researchers in the field, another coinage metal that is often overlooked—but is as powerful as the others—is silver, a far less costly alternative to gold and platinum in aiding the development of new reactions. Making a strong case for the use of silver as a catalyst and structural element in organometal constructs, this authoritative book is the first to explore the benefits of using silver in organic chemistry by taking a close look at silver’s unique reactivity and structural characteristics for the development of new methods and materials. Silver in Organic Chemistry is: The first book to address catalysis using silver, whose use in organic chemistry is on the verge of exploding A resource for researchers wishing to do chemistry with silver cations, an area that stands in the shadow of gold chemistry, but still glistens, demonstrating that all that glitters is not gold—sometimes it’s silver! A guide for “first attempts” in working with silver cations Edited by a very well-respected, highly visible authority in this field Silver in Organic Chemistry promotes further scientific discussion by offering important new ways to examine the future possibilities of an emerging field. By elevating the importance of silver chemistry, this thought-provoking guide illustrates how this versatile metal can become an increasingly significant player in opening the door to new catalytic organic reactions and new organometal materials.

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.

Download or read book Chemical Synthesis of Nucleoside Analogues written by Pedro Merino and published by John Wiley & Sons. This book was released on 2013-02-12 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compiles current tested and proven approaches to synthesize novel nucleoside analogues Featuring contributions from leading synthetic chemists from around the world, this book brings together and describes tested and proven approaches for the chemical synthesis of common families of nucleoside analogues. Readers will learn to create new nucleoside analogues with desired therapeutic properties by using a variety of methods to chemically modify natural nucleosides, including: Changes to the heterocyclic base Modification of substituents at the sugar ring Replacement of the furanose ring by a different carbo- or heterocyclic ring Introduction of conformational restrictions Synthesis of enantiomers Preparation of hydrolitically stable C-nucleosides Chemical Synthesis of Nucleoside Analogues covers all the major classes of nucleosides, including pronucleotides, C-nucleosides, carbanucleosides, and PNA monomers which have shown great promise as starting points for the synthesis of nucleoside analogues. The book also includes experimental procedures for key reactions related to the synthesis of nucleoside analogues, providing a valuable tool for the preparation of a number of different compounds. Throughout the book, chemical schemes and figures help readers better understand the chemical structures of nucleoside analogues and the methods used to synthesize them. Extensive references serve as a gateway to the growing body of original research studies and reviews in the field. Synthetically modified nucleosides have proven their value as therapeutic drugs, in particular as antiviral and antitumor agents. However, many of these nucleoside analogues have undesirable side effects. With Chemical Synthesis of Nucleoside Analogues as their guide, researchers have a new tool for synthesizing a new generation of nucleoside analogues that can be used as therapeutic drugs with fewer unwanted side effects.
Download or read book Carbohydrate Mimics written by Yves Chapleur and published by Wiley-VCH. This book was released on 1998-09-10 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbohydrate Mimics Concepts and Methods Edited by Yves Chapleur Apart from the various functions of carbohydrates in natural processes they are important building blocks for drugs, especially antibiotics. In addition, carbohydrates are considered as important structures in the immunological recognition process of the antigen-antibody reaction. The modification of the structure and thereby the chemistry of substrates is a common procedure in nature. This naturally occurring process is reflected in the concept of molecular mimicry, which has become a useful approach in drug discovery. The search for carbohydrate analogues that exhibit better binding activity, biological activity, and stability began with the synthesis of azasugars. A lot of structural modifications around the anomeric center of carbohydrates has been achieved over the last decade, and these are summarized in terms of the different chemical and biological aspects of carbohydrate mimics in one part of this book. In addition to the well established fields of C-glycosides, azasugars and carbasugars the other part of the book focusses on outstanding achievements in carbohydrate mimic research. Everybody who is active in carbohydrate research or is interested in moving into this exciting field will benefit from this up-to-date source of informations. The leading experts in this field describe their scientific approaches to real interdisciplinary puzzles. This book should be an inspiration to scientists in organic, medicinal chemistry, biochemistry, and biology.
