Download or read book Compendium of Chiral Auxiliary Applications, Three-Volume Set written by Gregory Roos and published by Academic Press. This book was released on 2002-01-04 with total page 1423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Compendium is a detailed compilation of chiral auxiliaries which are used in the field of organic chemistry to direct "asymmetric synthesis". A molecule is called chiral because it can have two "enantiomers" -- like left and right-handed molecules. An enantiomer is either of two molecules of the same chemical composition that are mirror images of each other but not identical. A "chiral auxiliary" is an aid / auxiliary used to specifically produce either the left or right enantiomer of the chosen molecule, as desired. In this comprehesive reference source, industrial chemists can make informed selections of an auxiliary for a specific application. It is fully cross-referenced to enable the comparative selection of auxiliaries. The work includes over 13,000 auxiliary reaction applications with complete reaction details of the synthetic routes, reagents, and primary literature references. Key Features * This remarkable major reference work is the first such compilation and represents the only total source for the diverse applications of auxiliaries * Thoroughly cross-referenced to enable comparative

Download or read book Chirogenesis In Chemical Science written by Victor Borovkov and published by World Scientific. This book was released on 2022-12-28 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chirogenesis in Chemical Science is an exciting new book that takes readers inside the world of chirality and chirogenesis, guided by Victor Borovkov and Riina Aav, both internationally renowned experts on chirality. Chirality is a fundamental property of the universe and has significance in different organic/inorganic materials, living organisms, and human beings. The basic principle of chirality is existence of an object in two mirror image forms, which are not superimposable. This phenomenon is widely seen in various fields of knowledge including mathematics, astronomy, physics, chemistry, biology and ranging in scale from galaxies to nuclear particles.In chemical science, chirality is generally associated with a single molecule or group of molecules, which symmetry properties belonging to the Cn or Dn point groups with the simplest example of sp3 carbon atom bonded to four different substituents. The dynamic processes of chirality generation, modulation, transfer, amplification, etc. are termed chirogenesis.This is a fast-growing and interdisciplinary field of research, which is widely seen in many natural systems (such as DNA double helix, the secondary alpha-helix structure of proteins, lipid membranes, saccharides, heme proteins, and other biological molecular objects) and various artificial systems. It is of prime importance not only for fundamental science but also for a number of practical applications in such areas as pharmacology and agrochemistry, perfumery and food industry, materials and polymer sciences, enantioselective catalysis and nonlinear optics, nanoscience and nanotechnology, molecular devices and chemical sensors, and others. Therefore, understanding the mechanisms and various influencing factors is of particular significance for smart control and further effective application of chirogenesis in chemistry.

Book Synopsis Chirality from Dynamic Kinetic Resolution by : Helene Pellissier
Download or read book Chirality from Dynamic Kinetic Resolution written by Helene Pellissier and published by Royal Society of Chemistry. This book was released on 2011-04-04 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last 15 years have witnessed significant developments in the efficiency and scope of the application of DKR. These now offer a serious alternative to conventional methods for asymmetric synthesis. Indeed, impressive examples using new enzymes and major progress in the DKR of racemates have taken place over the past few years. The powerful combination of enzymes and metals has also been the subject of spectacular development. In addition, a new type of DKR, involving organocatalysts, has recently appeared. Although asymmetric catalysis has undergone development during the last two decades, the most common industrial process used to obtain enantiomerically pure compounds is still via resolution of racemic mixtures. This is despite the major disadvantage that only a maximum of 50% product yield can be obtained. It is not surprising that DKR, which solves the problem of the limitation in yield, has attracted an increasing amount of interest from both the industrial and the academic perspective. This book provides an up-date on the principle methods employed to obtain dynamic kinetic resolution (DKR) by either enzymatic or non-enzymatic methods. It also illustrates the diversity of useful chiral products that can be obtained through this powerful concept. Divided into three sections, the book deals successively with non-enzymatic methods, enzymatic methods, and the use of transition metals and enzymes in tandem.

Book Synopsis Chirality in Supramolecular Assemblies by : F. Richard Keene
Download or read book Chirality in Supramolecular Assemblies written by F. Richard Keene and published by John Wiley & Sons. This book was released on 2016-11-14 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supramolecular chemistry deals with the organisation of molecules into defined assemblies using non-covalent interactions, including weaker and reversible interactions such as hydrogen bonds, and metal-ligand interactions. The aspect of stereochemistry within such chemical architectures, and in particular chirality, is of special interest as it impacts on considerations of molecular recognition, the development of functional materials, the vexed question of homochirality, nanoscale effects of interactions at interfaces, biocatalysis and enzymatic catalysis, and applications in organic synthesis. Chirality in Supramolecular Assemblies addresses many of these aspects, presenting a broad overview of this important and rapidly developing interdisciplinary field. Topics covered include: Origins of molecular and topological chirality Homochirogenesis Chirality in crystallinity Host-guest behavior Chiral influences in functional materials Chirality in network solids and coordination solids Aspects of chirality at interfaces Chirality in organic assemblies Chirality related to biocatalysis and enzymes in organic synthesis. This book is a valuable reference for researchers in the molecular sciences, materials science and biological science working with chiral supramolecular systems. It provides summaries and special insights by acknowledged international experts in the various fields.
Book Synopsis Amino Acids and the Asymmetry of Life by : Uwe Meierhenrich
Download or read book Amino Acids and the Asymmetry of Life written by Uwe Meierhenrich and published by Springer Science & Business Media. This book was released on 2008-08-15 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: "How did life originate and why were left-handed molecules selected for its architecture?" This question of high public and interdisciplinary scientific interest is the central theme of this book. It is widely known that in processes triggering the origin of life on Earth, the equal occurrence, the parity between left-handed amino acids and their right-handed mirror images, was violated. The balance was inevitably tipped to the left – as a result of which life's proteins today exclusively implement the left form of amino acids. Written in an engaging style, this book describes how the basic building blocks of life, the amino acids, formed. After a comprehensible introduction to stereochemistry, the author addresses the inherent property of amino acids in living organisms, namely the preference for left-handedness. What was the cause for the violation of parity of amino acids in the emergence of life on Earth? All the fascinating models proposed by physicists, chemists and biologist are vividly presented including the scientific conflicts. The author describes the attempt to verify any of those models with the chirality module of the ROSETTA mission, a probe built and launched with the mission to land on a comet and analyse whether there are chiral organic compounds that could have been brought to the Earth by cometary impacts. A truly interdisciplinary astrobiology book, "Amino Acids and the Asymmetry of Life" will fascinate students, researchers and all readers with backgrounds in natural sciences. With a foreword by Henri B. Kagan.

Book Synopsis Chemical Symmetry Breaking by : Rui Tamura
Download or read book Chemical Symmetry Breaking written by Rui Tamura and published by Mdpi AG. This book was released on 2021-07-26 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book entitled "Chemical Symmetry Breaking" is a collective volume of state-of-the-art reports on unique nonlinear chemical and physical symmetry-breaking phenomena that were experimentally observed upon a thermally or photochemically induced phase transition in various organic condensed phases, such as metastable liquid crystals, crystals, amorphous solids, and colloidal polymer materials, only under nonequilibrium conditions. Each author summarizes the introductory section in simple terms but in detail for beginners in this field. We wish that many readers familiarize themselves with the general concepts and features of nonlinear and nonequilibrium (or out of equilibrium) complexity theory, which govern a variety of unique dynamic behaviors observed in chemistry, physics, life science and other fields, so that they may discover novel symmetry-breaking phenomena in their own research areas.
