Synthesis Of Optically Active Alpha-Amino Acids

de R. M. Williams

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The purpose of this book is to review and critically evaluate the best new methods to synthesize alpha-amino acids in optically active form. There is so much new literature on amino acid synthesis that the experimentalist will undoubtedly have difficulty in selecting the most appropriate methodology for constructing the amino acid of immediate interest. This book is a guide for steering the scientist through the maze of existing reports on the subject and contains the most up-to-date critical reviews of methods of asymmetric synthesis of amino acids. In areas that are relatively new conceptually and less studied experimentally, an effort has been made to review the most salient works with an eye towards future development. Over 330 schemes and figures are presented with references for rapid visual retrieval of information. The book will be of great value to academic and industrial organic research chemists, especially those concerned with medicinal and agricultural chemistry, as well as to graduate and post graduate students, biochemists and biologists.

Sulphones In Organic Synthesis

de N S. Simpkins

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Over the last twenty years the use of sulphones in organic synthesis has increased dramatically, the synthetic repertoire of sulphones having been developed to such an extent as to rival the carbonyl functionality for versatility. Not only have sulphones been employed in a great many synthetic methodologies, enabling the preparation of a vast array of functionalised products, but the sulphone group has also proved to be of enormous value in many of the most demanding and sophisticated total syntheses carried out in recent years. This book describes in detail all of the important sulphone chemistry employed in organic synthesis, ranging from the well-established sulphone-mediated methods to less familiar sulphone reactions and very recent discoveries of synthetic potential.

Organic Syntheses Based On Name Reactions And Unnamed Reactions

de Alfred Hassner e C Stumer

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Synthetically useful organic reactions or reagents are often referred to by the name of the discoverer(s) or developer(s). Older name reactions are described in text books, but more recently developed synthetically useful reactions that may have been associated occasionally with a name are not always well known. For neither of the above are experimental procedures or references easy to find.In this monograph approximately 500 name reactions are included, of which over 200 represent newer name reactions and modern reagents. Each of these reactions are extremely useful for the contemporary organic chemistry researcher in industry or academic institutions. This book provides the information in an easily accessible form.In addition to seminal references and reviews, one or more examples for each name reaction are provided and a complete typical experimental procedure is included, to enable the student or researcher to immediately evaluate reaction conditions.Besides an alphabetical listing of reactions and reagents, cross references permit the organic practitioner to find those name reactions or reagents that enable specific transformations, such as, conversion of amines to nitriles, stereoselective reduction, fluoroalkylation, phenol alkynylation, asymmetric syntheses, allylic alkylation, nucleoside synthesis, cyclopentanation, hydrozirconation, to name a few. Emphasis has been placed on stereoselective and regioselective transformations as well as on enantioselective processes. The listing of reactions and reagents is supported by four indexes.

Selenium Reagents & Intermediates In Organic Synthesis

de C. Paulmier

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 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.

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Although organotransition metal chemistry has been developing rapidly over the past 20 years, it is only recently that applications of transition metal complexes to organic synthesis have started to be exploited. This unique book provides an introduction to organometallic chemistry for chemists who have little or no experience in the field, describes the work that has already been done using organotransition metal complexes for synthesis, and indicates to organic and organometallic chemists the type of synthetic problems that can be solved using organometallic compounds. It covers all major advances that have been made in this rapidly expanding area of chemistry, including not only reactions that already have well established applications for synthesis but also many recently discovered potentially useful reactions, providing a survey of recent literature.
