Download or read book Basic Concepts in Organic Stereochemistry written by Sunil Kumar Talapatra and published by Springer Nature. This book was released on 2023-01-01 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses essential stereochemical concepts associated with organic molecules (natural or synthetic), as reflected in the course of their many reactions, their mechanisms, their asymmetric synthesis, biosynthesis, and biological activities. This treatise provides useful insights and understanding of the chiral/achiral designations (nomenclatures), the stereochemical features, and related properties of the natural and synthetic products. Without having an adequate knowledge of stereochemical concepts, it will not be possible to understand and appreciate the stereochemistry of natural or synthetic products. Thus, essential static and dynamic aspects of stereochemistry with sufficient illustrative examples along with discussions are presented. The structure of the monograph allows for easy selection of separate topics for reading and teaching. This book will also provide an idea of basic stereochemical concepts, as applied to organic molecules in general as well as to organic ligands in coordination complexes, and will, therefore, be valuable resources to teachers and students of advanced undergraduates and post-graduates, researchers, and professionals.

Download or read book The Exploration of Supramolecular Systems and Nanostructures by Photochemical Techniques written by Paola Ceroni and published by Springer Science & Business Media. This book was released on 2011-11-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Exploration of Supramolecular Systems and Nanostructures by Photochemical Techniques provides a comprehensive view of the most commonly used photochemical and photophysical techniques and their applications to the study of supramolecular systems. Optical inputs are extremely powerful in the study of nanostructures since they can be used both to “read” the state of the system and to provide it energy to work. After a brief introduction to the realm of photochemistry, electronically excited state formation and the different pathways of excited state deactivation, the book focuses on the theoretical basis and the practical aspects related to the most widely used photophysical and photochemical techniques, from absorption to time-resolved emission techniques with polarized light. Each chapter illustrates an example of the application of that particular technique to the study of a supramolecular system. The Exploration of Supramolecular Systems and Nanostructures by Photochemical Techniques not only discusses the latest advances of the field of supramolecular photochemistry but it also offers technical and operative details useful in the laboratory. It is therefore suitable for both the novice and the expert.

Download or read book Principles of Asymmetric Synthesis written by Robert E. Gawley and published by Elsevier. This book was released on 2012-05-29 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is chiral. Most of the molecules in it are chiral, and asymmetric synthesis is an important means by which enantiopure chiral molecules may be obtained for study and sale. Using examples from the literature of asymmetric synthesis, this book presents a detailed analysis of the factors that govern stereoselectivity in organic reactions. After an explanation of the basic physical-organic principles governing stereoselective reactions, the authors provide a detailed, annotated glossary of stereochemical terms. A chapter on "Practical Aspects of Asymmetric Synthesis" provides a critical overview of the most common methods for the preparation of enantiomerically pure compounds, techniques for analysis of stereoisomers using chromatographic, spectroscopic, and chiroptical methods. The authors then present an overview of the most important methods in contemporary asymmetric synthesis organized by reaction type. Thus, there are four chapters on carbon-carbon bond forming reactions, one chapter on reductions, and one on oxidations (carbon-oxygen and carbon-nitrogen bond forming reactions). This organization allows the reader to compare the leading methods for asymmetric synthesis in an appropriate context. A highlight of the book is the presentation and discussion of transition states at the current level of understanding, for important reaction types. In addition, extensive tables of examples are used to give the reader an appreciation for the scope of each reaction. Finally, leading references are provided to natural product synthesis that has been accomplished using a given reaction as a key step. - Authoritative glossary to aid understanding of stereochemical terminology - Explanations of the key factors influencing stereoselectivity with numerous examples, organized by reaction type - A handy reference guide to the literature of asymmetric synthesis for practitioners in the field
