Download or read book Comprehensive Chirality written by and published by Newnes. This book was released on 2012-12-31 with total page 5635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although many books exist on the subject of chiral chemistry, they only briefly cover chiral synthesis and analysis as a minor part of a larger work, to date there are none that pull together the background information and latest advances in one comprehensive reference work. Comprehensive Chirality provides a complete overview of the field, and includes chiral research relevant to synthesis, analytic chemistry, catalysis, and pharmaceuticals. The individual chapters in each of the 9 volumes provide an in depth review and collection of references on definition, technology, applications and a guide/links to the related literature. Whether in an Academic or Corporate setting, these chapters will form an invaluable resource for advanced students/researchers new to an area and those who need further background or answers to a particular problem, particularly in the development of drugs. Chirality research today is a central theme in chemistry and biology and is growing in importance across a number of disciplinary boundaries. These studies do not always share a unique identifying factor or subject themselves to clear and concise definitions. This work unites the different areas of research and allows anyone working or researching in chiral chemistry to navigate through the most essential concepts with ease, saving them time and vastly improving their understanding. The field of chirality counts several journals that are directly and indirectly concerned with the field. There is no reference work that encompasses the entire field and unites the different areas of research through deep foundational reviews. Comprehensive Chirality fills this vacuum, and can be considered the definitive work. It will help users apply context to the diverse journal literature offering and aid them in identifying areas for further research and/or for solving problems. Chief Editors, Hisashi Yamamoto (University of Chicago) and Erick Carreira (ETH Zürich) have assembled an impressive, world-class team of Volume Editors and Contributing Authors. Each chapter has been painstakingly reviewed and checked for consistent high quality. The result is an authoritative overview which ties the literature together and provides the user with a reliable background information and citation resource.

Download or read book Asymmetric Synthesis of Bioactive Lactones and the Development of a Catalytic Asymmetric Synthesis of Aryl Ketones written by Robert Doran and published by Springer. This book was released on 2015-06-24 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Chiral Bisoxazoline Ligands in Catalytic Asymmetric Allylic Oxidation written by Davoud Asgari and published by LAP Lambert Academic Publishing. This book was released on 2009-09 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Past three decades have witnessed a major development in asymmetric catalysis in organic synthesis. New and powerful catalysts have been designed and developed which exhibit levels of enantioselectivity previously considered beyond reach for non-enzymatic processes. Nitrogen-based transition metal ligands such as bisoxazoline ligands have emerged as an efficient class of ligands in an increasing number of asymmetric transformations including cyclopropanation, aziridination, Diels-Alder reaction, reduction, aldol reaction, ene reactions, allylic oxidation, and etc. This book reviews the synthesis and applications of bisoxazoline-metal complexes in a variety of asymmetric transformations and then describes the design and synthesis of a novel class of C2-symmetric biarylbisoxazoline ligands and their application in copper catalyzed asymmetric allylic oxidation of olefins. Potential applications for chiral cycloalkenols derived from allylic oxidation are great. A clear example is the conversion of (S)-cyclohexenyl benzoate to the key aldehyde-methyl ester intermediate for the synthesis of inflammation mediator leukotriene B4.

Available in PDF, EPUB and Kindle. Book excerpt: Asymmetric C-H direct functionalization reactions are one of the most active and fascinating areas of research in organic chemistry due to their significance in the construction of molecular complexity without pre-activation, and the step economy and atom economy features in potential synthetic application. Distinguishing the reactivity among numerous C–H bonds in one single molecule represents one of the most challenging issues in organic synthesis and requires precise reaction design. As such, this field is now receiving increasing attention from researchers. This book provides the first comprehensive review of this field, summarizing the origin, mechanism, scope and applications of the asymmetric C-H bond functionalization reaction. It covers organocatalytic reactions and transition-metal-catalyzed reactions, as well as asymmetric C-H functionalization reactions not described in other books. Written by a leading expert in this field, the book is ideal for postgraduates and researchers working in organic synthesis, catalysis, and organometallic chemistry.

Download or read book Hydrogen Transfer Reactions written by Gabriela Guillena and published by Springer. This book was released on 2016-09-27 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
