Bisher gab es kein Buch, das sich speziell mit der Chiralität von Agrochemikalien beschäftigte, obwohl dieses Gebiet zunehmende Beachtung in der Industrie findet. Diese Darstellung der Chiralität bei Insektiziden, Fungiziden, Herbiziden und anderen Klassen von Agrochemikalien schließt diese Lücke. Synthese, Analytik, biologische Aktivität, Wirkprinzip, Toxikologie, Metabolismus und Umweltschicksal jeder besprochenen Verbindung werden diskutiert. (8/98)

This second volume of Chirality in Industry contains new case histories from a wide range of contributors from industry or with strong industrial connections. While it is intended that the new volume will stand on its own, Volumes I and II taken together present an up-to-date and comprehensive picture of the technologies required to produce optically active compounds on a multi-kilogramme to high tonnage scale as well as illustrating the breadth of application of these technologies; the pharmaceuticals, agrochemicals, electronics, food, flavour and fragrance industries are all represented. Chirality in Industry II All new case histories Unique industrial perspective on chiral technology Emphasis on scale-up and process development Comparison of biocatalysis, asymmetric synthesis and classical resolution approaches The chiral infrastructure is now largely in place and there is no reason why large-scale production should not be possible for even moderately priced single enantiomer products. The successful industrial application of chiral chemistry depends on the integration of a range of supporting technologies and there are many examples in this volume of how widely the industrial practitioner must cast the net to achieve practical production methods. As with Volume I, this new volume is of particular interest to those professionally involved in the scale-up processes for single enantiomers. However, students and researchers involved in a more academic pursuit of optical activity will also benefit from some of the facets of large-scale thinking. An economic solution is still most likely to be a simple, elegant solution.

This title was first published in 2001: In the early twentieth century the relevance of chirality to the pharmaceutical industry was established by the fact that one enantiomer of hyoscyamine possessed greater pharmacological activity than the other. Today, most new drugs and those under development consist of a single optically active isomer, and chirality is also becoming an issue for the agrochemical and other industries. Regulatory agencies throughout the world are currently reviewing the importance of chirality with regard to pharmaceutical and agrochemical products. New guidelines from such agencies have been key drivers for the focus on single enantiomer products in these industries. These scientific and regulatory developments have created the need for a guide for workers in the pharmaceutical and chemical industries seeking information on chiral molecules, processes, and commercially available chiral chemicals. Chiral Drugs is a comprehensive listing of over 2500 chiral drugs, classified by therapeutic class, and including structures and physical properties for each entry in the listing. Its companion volume, Chiral Intermediates, presents the same detailed information for over 4700 commercially available chiral chemicals. The 'Chiral Pool' of readily available, relatively inexpensive chiral compounds has been expanding at a rapid rate as more and more products are produced in large quantities at economical prices. New developments in various technologies for isolating, preparing, and purifying chiral materials have greatly increased the opportunities for utilizing optically pure compounds in commercial applications. Novel techniques for classical resolution, new methodologies for developing selective enzymes for biocatalysis, advances in the application of microorganisms for chemical production, and continued progress in the area of asymmetric synthesis have all contributed to the growth of this field. Part One of each book contains four chapters which provide an introduction to topics relevant to the field of chiral chemistry and includes a brief overview of chirality, a short discussion on the current market drivers in the area of chiral chemistry, and a basic presentation of the various sources and methods for obtaining chiral compounds. Part Two presents entries for over 2500 chiral drugs, classified by therapeutic class. For each main entry, the chemical name and a list of trade names and synonyms is provided; the CAS Registry Number, the European Inventory of Existing Commercial Chemical Substances (EINECS) number, and the Merck Index (12th edition) number are given when available. The physical properties, including specific rotation, of each compound are described and indicated applications are presented. The structure of nearly every compound is provided, and the manufacturers and suppliers of the compounds are also given. Indexes, including a master index of names and synonyms and an index of custom manufacturing services for production of chiral compounds, are appended. Chiral Drugs provides an introduction to the types of sources and methods currently in use for obtaining chiral molecules and is an invaluable resource for researchers in the pharmaceutical and biotechnology sectors as well as to those working in the basic biochemical sciences. Chiral Intermediates provides an introduction to the types of sources and methods currently in use for obtaining chiral molecules and is an invaluable resource for information on available chiral molecules. Chiral Intermediates and Chiral Drugs are the most comprehensive and detailed guides to chiral compounds available.

Recently there has been growing concern about the hazards for man and his environment due to exposure to chemicals. One aspect receiving particular attention is that of the neglect of stereoselectivity in bioactive agents such as pesticides, drugs, etc. Mixtures of stereoisomers often contain 50 percent inactive material in the form of isomeric ballast. This ballast is pure environmental pollutant. Decisions as to whether the use of mixtures of stereoisomers is acceptable are only possible and acceptable if they are based on sound scientific information. It is the purpose of this volume to contribute to, and to disseminate, knowledge in this field. Written for workers in the field of pesticides, the book contains concise and basic information on stereoselectivity as a notable source of problems. Attention is paid to the involvement of stereoselectivity in important classes of pesticides as well as to pheromones and compounds derived from insect hormones with potential use in crop protection. Fundamentals of stereochemistry, stereoselective analytical methods, stereoselective synthesis and stereochemical aspects of the design of new compounds are also discussed.

The book deals with the recognition of asymmetry in molecules of practical utility in revolutionary chemistry. The book consists of six chapters quoted with references. The first chapter includes the introductory evolution, drug discovery from so many years ago. Why the optically pure fragrances have much pleasant odour also described. The other chapters designed taking specific class of compounds. Second chapter involves so many features about the chiral drugs. Third chapter reveals Chiral flavor, fragrances, food & natural oil in market.Fourth chapter tells about the chiral agrochemicals, herbicides and fungicides according to market survey.Fifth chapter is about a brief of chiral natural & synthetic Polymer & how stereochemistry designed in polymers. Sixth chapter describe a short story of optically active Metal complexes and their application.Perhaps this book shows the introductory part of almost type of chiral products. The portion of definitions & abbreviation are kept at the end of book. This will help to know some technical or important keywords.

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.
