Die wichtigsten und nützlichsten Methoden der modernen stereoselektiven Synthese sind in diesem Band zusammengefasst. Viele anschauliche Beispiele für die Darstellung von Wirkstoffen und Naturstoffen regen zur gezielten Abwandlung und Integration in eigene Synthesewege an. Dabei geht es den Autoren weniger darum, das Gebiet in seiner Gesamtheit darzustellen; vielmehr versuchen sie, die wirklich grundlegenden Ansätze auszuwählen, die jeder organische Synthesechemiker kennen und anwenden sollte.

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.

The state-of-the-art in stereoselective synthesis! Thoroughly revised and updated, this enlarged second edition offers a plethora of valuable information on methods and reagents in stereoselective synthesis. Methods have been selected for high efficiency and selectivity; mechanistic aspects are treated succinctly, with a strong emphasis on practical applications. For this new edition, material has been added on * homogeneous diastereoselective hydrogenations * enantioselective oxidations * novel, efficient chiral auxiliaries Much of the information given is presented in figures and tables, which makes the book a valuable reference work for the practically minded organic chemist. From reviews of the first edition: 'The extensive material in the volume should prove particularly useful to anyone involved in synthetic chemistry or teaching a course in organic chemistry.' Journal of Medicinal Chemistry 'With nearly 1400 references cited, the book contains a wealth of information and should be a useful addition to the chemist's library.' The American Scientist

Studies in Natural Products Chemistry, Volume 14: Stereoselective Synthesis, Part I is a collection of discourses on the stereoselective synthesis of the anticancer anthrucycline antibiotics; tetramic acid antibiotics; 3-and 4-deoxyhexoses; polysaccharides; levoglucosenone as precursor to natural products; synthesis of oligoribonucleotides; and oxidation of guaiazulene. This volume deals with a broad range of natural products focusing on the synthesis of antibiotics and anticancer agents — anthracyclines, tetramic acid, taxodione, vinblastine, and vincristine. These aforementioned drugs are used for the treatment of cancer (anthracyclines) and Hodgkin's disease and childhood acute leukemia (vinblastine and vincristine). The importance of the latest developments in the stereocontrolled synthesis of polysaccharides is discussed as polysaccharides play a fundamental role in cell life and have many technical applications. The synthesis of bioactive carbohydrates 3- and 4-deoxy-hexoses is compared with the more occurring deoxyhexoses in nature such as the 2-deoxy, 6-deoxy, and 2,6-dideoxy-hexoses, because the former are rare compounds and useful tools in the study of biological and biochemical properties of mono- and oligosaccharides, glycoproteins, and antibiotics. Alkaloids derived from Apocynaceae are known for their medicinal properties; hence the synthetic approaches to vinblastine and vincristine are discussed. Because of the minute amounts available from herbal sources, efforts toward their chemical synthesis are given more reference. This book can be a useful reference for the organic chemists. Chemical researchers, pharmaceutical scientists, and professionals of bioorganic chemistry will likewise gain a lot from this collection.

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.
