Written by world-renowned and best-selling experts, Nobel Laureate E. J. Corey and Laszlo Kurti, Enantioselective Chemical Synthesis offers an authoritative and comprehensive overview of the field s progress; the processes and tools for key formations; future development for complex, stereocontrolled (enantiomeric or diastereoisomeric) molecules; and valuable examples of multi-step syntheses. Utilizing a color-coded scheme to illustrate chemical transformations, Enantioselective Chemical Synthesis provides clear explanation and guidance through vital asymmetrical syntheses and insight into the next steps for the field. Researchers, professionals, and academics will benefit from this valuable, thorough, and unique resource. In Part I, the authors present clearly, comprehensively and concisely the most useful enantioselective processes available to synthetic chemists. Part II provides an extensive discussion of the most logical ways to apply these new enantioselective methods to the planning of syntheses of stereochemically complex molecules. This hitherto neglected area is essential for the advancement of enantioselective synthesis to a more rational and powerful level. Part III describes in detail many reaction sequences which have been used successfully for the construction of a wide variety of complex target molecules Clearly explains stereochemical synthesis in theory and practiceProvides a handy tool box for scientists wishing to understand and apply chiral chemical synthesisDescribes almost 50 real life examples of asymmetric synthesis in practice and examines how the chiral centers were introduced at key synthetic stages"

In this thesis, the author describes the total synthesis of natural product Maoecrystal V in detail. In the first part of the thesis, the author introduces the research background and reviews the research progress in total synthesis of Maoecrystal V. In the second part, the author develops a novel and concise approach for the stereo selective construction of the tetracyclic model system of Maoecrystal V. The model system is accomplished in 8 steps with 20% yield. In the third part, the author describes the first successful total synthesis of Maoecrystal V and investigates four strategies for constructing the key tetrahydrofuran oxa-bridge skeleton. The total synthesis starts from a known compound and is accomplished in 17 steps with 1.2% yield. The successful total synthesis of Maoecrystal V will contribute to the development of efficient synthetic strategies for natural products and other compounds with complex structures.

Following on from Advances in BioChirality, Progress in Biological Chirality provides a unique summary and review of the most recent developments in the field of biochirality. Living organisms use only one enantiomer of chiral molecules in the majority of biologically important processes. The exact origin and mechanisms for this surprising selectivity are not yet known. This book discusses current research aimed at identifying the scientific reasons that may contribute to this phenomenon. Progress in Biological Chirality takes an interdisciplinary approach to this exciting field, covering a wide range of topics, such as, theory, palaeontology and food technology, to name but a few. This book presents findings via a broad spectrum of scientific approaches making it an excellent overview of Biological Chirality, suitable for postgraduate students, practitioners and researchers in the field of chemistry, biochemistry, biology, palaeontology, and food science with an interest in Chirality. - This book contains 32 chapters written by Authors, who are leading authorities in the field - Presents the most recent research taking place in this highly challenging field - Contains both reference material for the specialist and provides an overview for those who are interested in the fundamental problems of biology and chemistry

This thesis addresses two fundamental areas in contemporary organic chemistry: synthesis of natural products and catalytic asymmetric synthesis. Firstly, a new methodology, developed by our research group, which allows the asymmetric synthesis of lactones, a structural unit ubiquitous in natural products, was utilised in the synthesis of a number of natural product analogues that showed significant biological activity. Secondly, the development of a catalytic asymmetric synthesis of a key structural motif present in a number of natural products and pharmaceuticals was accomplished. During the course of this work we discovered dual stereo control, which is significant because it allows the configuration of a new stereo centre to be controlled by a simple change of proton source.

ISBN: 303016585X

This book collects recent advances in the field of nonlinear dynamics in biological systems. Focusing on medical applications as well as more fundamental questions in biochemistry, it presents recent findings in areas such as control in chemically driven reaction-diffusion systems, electrical wave propagation through heart tissue, neural network growth, chiral symmetry breaking in polymers and mechanochemical pattern formation in the cytoplasm, particularly in the context of cardiac cells. It is a compilation of works, including contributions from international scientists who attended the “2nd BCAM Workshop on Nonlinear Dynamics in Biological Systems,” held at the Basque Center for Applied Mathematics, Bilbao in September 2016. Embracing diverse disciplines and using multidisciplinary approaches – including theoretical concepts, simulations and experiments – these contributions highlight the nonlinear nature of biological systems in order to be able to reproduce their complex behavior. Edited by the conference organizers and featuring results that represent recent findings and not necessarily those presented at the conference, the book appeals to applied mathematicians, biophysicists and computational biologists.

Chiral Building Blocks in Asymmetric Synthesis A comprehensive introduction to the important classes of chiral building blocks Chirality — the asymmetric quality found in certain chemical compounds — plays an essential role in our world: chiral compounds can be found in biology, pharmaceutical compounds, agrochemicals, and fragrances. The stereoselective preparation of these complex molecular constructions constitutes a challenge. To this end, modern asymmetric synthesis utilizes a variety of valuable and efficient reagents employed as chiral auxiliaries, metal complexes and organocatalysts in stereoselective catalysis, and enantiopure reactants termed as chiral building blocks. In Chiral Building Blocks in Asymmetric Synthesis, the achievements in the fields of preparation of and applications of chiral blocks are presented. In doing so, the book comprehensively discusses the important classes of these reactants as the key for the asymmetric synthesis of chiral molecules. As such, it is an indispensable resource about synthetic methods, as well as possible modifications and transformations of important classes of chiral compounds. It also highlights the importance of their use as reactants and auxiliaries in the preparation of more sophisticated molecules or supramolecular systems. In Chiral Building Blocks in Asymmetric Synthesis readers will also find: Organization according to the most important compound classes — e.g. amino acids, BINOL and its derivatives, terpenes, and others — with an emphasis on synthesis and application A focus on the use of chiral building blocks for the preparation of bioactive compounds and supramolecular assemblies Chiral Building Blocks in Asymmetric Synthesis is a useful reference for organic chemists, catalytic chemists, chemists in industry, medicinal chemists, pharmaceutical chemists, and the libraries that support them.
