Book Description
As pharmaceutical companies look to develop single enantiomers as drug candidates, chemists are increasingly faced with the problems associated with this subclass of organic synthesis. "The Handbook of Chiral Chemicals, Second Edition" highlights the problems associated with the production of chiral compounds on a commercial scale. The handbook first elaborates upon starting materials obtained from a 'chiral pool', which can be derived from natural products. Then it explains methods and reactions that can introduce or influence stereogenic centers, particularly asymmetric hydrogenations, oxidations, pericyclic reactions, and enzymatic methods.While hydrogenations have been the most widely employed approach for the large-scale synthesis of several commercial compounds, the search for the ideal catalyst has consistently led researchers to enzymes present in biological systems. Several chapters concentrate on understanding how to manipulate enzymes for catalyzing new reactions for taking new substrates. Other significant topics include chiral auxiliaries, chromatographic techniques, enantiomers-specific reactions, and resolution. This second edition updates all its chapters, illustrating the speed of development in this field, and features new chapters that highlight successful approaches in an industrial setting. "The Handbook of Chiral Chemicals, Second Edition" is a guide to advances in the field that result in more efficient and cost-effective synthesis of chiral chemicals.

Book Description
An integrated view of chiral drugs from concept and synthesisto pharmaceutical properties Chirality greatly influences a drug's biological and pharmacological properties. In an effort to achieve more predictable results from chiral drugs, the Food and Drug Administration now requires that these medicines be as pure as possible, which places great demands on drug synthesis, purification, analysis, and testing. To assist researchers in acquiring the essential knowledge to meet these rigid guidelines, Chiral Drugs focuses on three vital chiral technologies asymmetric synthesis, biocatalytic process, and chiral resolution to offer details on the basic concepts, key developments, and recent trends in chiral drug discovery, along with: The history of chiral drugs development and industrial applications of chiral technologies A section listing twenty-five approved or advanced-trial chiral drugs that lists each drug name, chemical name and properties, a representative synthetic pathway, pharmacological characterizations, and references An interdisciplinary approach combining synthetic organic chemistry, medicinal chemistry, and pharmacology Nearly two-thirds of the drugs on today's market are chiral drugs. Reducing and eliminating their negative characteristics is an ongoing and serious challenge for the pharmaceutical industry. With its well-balanced approach to covering each important aspect of chirality, Chiral Drugs champions important strategies for tipping the medical scale in a positive direction for the production of more effective and safer drugs.

Book Description
Optically active compounds are gaining ever-increasing importance in organic chemistry, both in the academic and the industrial arenas. The rational synthesis of the growing number of chiral chemicals, drugs, and natural products demands efficient methods for producing these compounds in an enantiomerically, highly pure form. Despite the available alternative techniques, optical resolution via Diastereomeric salt formation remains the most widely used method of preparing pure enantiomers. The CRC Handbook of Optical Resolutions Via Diastereomeric Salt Formation is the first book to exclusively address this important organic chemical process. It provides fast, one-stop access to a wealth of information, including all of the available data on 100 resolving agents, a list of 500 optically active compounds available in bulk along with their suppliers, data on more than 3,500 resolutions, and 4,200 citations. This handbook helps answer virtually any question that may arise during the development of a new resolution process. Which resolving agent and solvent should I use under these conditions? How can I separate the diastereoisomers? How can I optimize a resolution process? How do I determine enantiomeric purity? Which supplier has the resolving agent I need? For a racemate already resolved, what were the resolving agent, solvent, and relevant citation? This is the first book to deal exclusively with all aspects of this important organic chemical process, both theoretical and practical. With an abundance of analyzed examples, this single, authoritative reference provides all of the information you need to perform, develop, and optimize optical resolutions via Diastereomeric salt formation

Book Description
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 Intermediates presents the chemical professional with a comprehensive listing of over 4700 available chiral chemicals including specific data of interest for each entry in the listing. Its companion volume, Chiral Drugs presents the same detailed information for over 2000 chiral drugs. 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 I 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 II presents entries for 4700 commercially available chiral compounds. 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 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.

Book Description
Divided into the three main sections of synthesis, analysis and drug development, this handbook covers all stages of the drug development process, including large-scale synthesis and purification of chirally pure pharmaceuticals. The two editors from academia and a major pharmaceutical company have assembled an experienced, international team who provide first-hand practical advice and report previously unpublished data. In the first section, the isolation of chiral drugs from natural sources, their production in enzymatic processes and the resolution of racemic mixtures in preparative chromatography are outlined in separate chapters. For the section on qualitative and quantitative analysis, enantioselective chromatographic methods are presented as well as optical methods and CE-MS, while the final section deals with the pharmacology, pharmacokinetics and metabolic aspects of chiral drugs, devoting whole chapters to stereoselective drug binding and modeling chiral drug-receptor interactions. With its unique industry-relevant aspects, this is a must for medicinal and pharmaceutical chemists.
