Download or read book Stereoselective Synthesis in Organic Chemistry written by Atta-ur-Rahman and published by Springer. This book was released on 2011-12-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monumental tome by Prof. Atta-ur-Rahman and Dr. Zahir Shah pres­ ents a broad overall perspective of stereo selectivity in the synthesis of or­ ganic molecules. Thus it treats a problem that is of fundamental importance and will be even more important in the future as the drug industry is required to supply 1000/0 optically pure compounds. After an exposition of general principles, the following subjects are treated: Catalytic Reductions, Heterogeneous Catalytic Hydrogenations, Stereoselective Non-Catalytic Reductions, Stereos elective Carbon-Carbon Bond Forming Reactions, Asymmetric Oxidations, Asymmetric Carbon­ Heteroatom Bond Formations, Enzyme Catalyzed Reactions, Stereo­ selective Free Radical Reactions, and finally Miscellaneous Stereoselective Reactions. For each subject, a wealth of examples are given. The highly selective reactions are mentioned along with reactions that are not. This is helpful as it will teach the practical chemist what to avoid. Much progress has been made in the last two decades in the design of new, very stereoselective reactions which can be applied in industry. For example, and in alphabetical order, we can mention (among other peers): H.C. Brown (hydroboration), D.C. Evans (carbon-carbon bond forma­ tion), R. Noyori (BINAP reagents for hydrogenation), and K.B. Sharpless (epoxidation and dihydroxylation of double bonds). Thus the field has completely changed since the 1950s, when optically pure compounds were always obtained by difficult resolutions of racemates and not by stereoselec­ tive reactions.

Download or read book Biotransformations in Organic Chemistry written by Kurt Faber and published by Springer. This book was released on 2011-07-28 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of biocatalysts, employed either as isolated enzymes or whole microbial cells, offers a remarkable arsenal of highly selective transformations for state-of-the-art synthetic organic chemistry. Over the last two decades, this methodology has become an indispensable tool for asymmetric synthesis, not only at the academic level, but also on an industrial scale. This well-established textbook on biocatalysis provides a basis for undergraduate and graduate courses in modern organic chemistry, as well as a condensed introduction into this field. After a basic introduction into the use of biocatalysts—principles of stereoselective transformations, enzyme properties and kinetics—the different types of reactions are explained according to the 'reaction principle', such as hydrolysis, reduction, oxidation, C–C bond formation, etc. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and modified or artificial enzymes, are treated in a separate section. A final chapter deals with thebasic rules for the safe and practical handling of biocatalysts. In this completely revised 6th edition, emphasis has been given to an improved didactic style including colored graphics in order to facilitate a deeper understanding of the underlying principles. New developments, such as transamination, enzyme promiscuity and applications on industrial scale within the field of 'white biotechnology' are included.

Download or read book Organic Syntheses Based on Name Reactions and Unnamed Reactions written by Alfred Hassner and published by Elsevier. This book was released on 2013-10-22 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018-03-02 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade a new era in asymmetric catalysis has been realised by the discovery of L-proline induced chiral enamines from carbonyls. Inspired by this, researchers have developed many other primary catalytic species in situ, more recently secondary catalytic species such as aminals have been identified for use in asymmetric synthesis. High-yielding asymmetric synthesis of bioactive and natural products through mild catalysis is an efficient approach in reaction engineering. In the early days, synthetic chemists mainly focused on the synthesis of complex molecules, with less attention on the reaction efficiency and eco-friendly conditions. Recent investigations have been directed towards the development of atom economy, eco-friendly and enantioselective synthesis for more targeted and efficient synthesis. Building on the momentum of this rapidly expanding research area, Dienamine catalysis for organic synthesis will provide a comprehensive introduction, from the preformed species, in situ generation and onto their applications in the synthesis of bioactive molecules and natural products.

Download or read book Biotransformations in Organic Chemistry written by Kurt Faber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of natural catalysts - enzymes - for the transformation of non-natural is not at all new: they have been used for more man-made organic compounds than one hundred years, employed either as whole cells, cell organelles or isolated enzymes [1]. Certainly, the object of most of the early research was totally different from that of the present day. Thus the elucidation of biochemical pathways and enzyme mechanisms was in the foreground of the reasearch some decades ago. It was mainly during the 1980s that the enormous potential of applying natural catalysts to transform non-natural organic compounds was recognized. What started as a trend in the late 1970s could almost be called a fashion in synthetic organic chemistry in the 1990s. Although the early euphoria during the 'gold rush' in this field seems to have eased somewhat, there is still no limit to be seen for the future development of such methods. As a result of this extensive, recent research, there have been an estimated 5000 papers published on the subject [2]. To collate these data as a kind of 'super-review' would clearly be an impossible task and, furthermore, such a hypothetical book would be unpalatable for the non-expert.
