| conformational analysis organic chemistry: Conformational Analysis G Chiurdoglu, 2012-12-02 Conformational Analysis: Scope and Present Limitations contains the proceedings of the Brussels International Symposium on Conformational Analysis held in Brussels, Belgium, in September 1969. The papers focus on the theoretical aspects and applications of conformational analysis, such as those concerning the aliphatic and especially the cyclic series. Topics covered include the geometry of five-membered rings; conformational transmission in steroids; conformational aspects of N-quaternization; and applications of nuclear magnetic resonance spectrometry in conformational studies of cyclohexane derivatives. This book is comprised of 20 chapters and begins with a discussion on the conformational aspects of some five-membered ring compounds based mainly on observed (diffraction methods) and calculated torsional angles. The reader is then introduced to nuclear magnetic resonance studies of the conformations and conformational barriers in cyclic molecules; conformational studies of six-membered heterocycles; conformational transmission in steroids; and solvolytic cyclizations involving double bonds. The remaining chapters explore the conformational analysis of methylcyclohexane, cyclohexane systems, and carbonium ions; conformations of membrane-active cyclodepsipeptides; energetics of isomeric transition states and competitive reaction pathways in conformational analysis; and conformational aspects of the reaction of the 1-methylcyclodecane-l,6-diols with acid. This monograph will be of interest to organic chemists. |

| conformational analysis organic chemistry: Modern Conformational Analysis Helena Dodziuk, 1996-12-17 Viele Bücher über organische Zusammensetzungen behandeln die Stereochemie, schenken aber der räumlichen Struktur der organischen Moleküle, vor allem der weniger gebräuchlichen, kaum Beachtung. Diese Monographie stellt nun ein umfassendes Werk zur organischen Struktur und der Konformationsanalyse dar. Das Interesse des Autors an der Formenvielfalt der organischen Moleküle spiegelt sich besonders intensiv in der Betrachtung der Molekülordnung wider, die in organisch chemischen und biologischen Systemen von großer Bedeutung ist. Der neue Band in der Reihe 'Methods in Stereochemical Analysis' stellt vor allem diese Bedeutung der Molekülgestalt und die Einwirkung theoretischer Studien und synthetischer Chemie zu diesem Themenkomplex in den Vordergrund. |

| conformational analysis organic chemistry: The Anomeric Effect Eusebio Juaristi, Gabriel Cuevas, 1994-10-12 This book provides a comprehensive review of the structural, conformational, and chemical manifestations of the anomeric effect. In order to present a cogent discussion of this most fundamental and relevant phenomenon, three chapters examine our present understanding of the origin of this conformational effect, based upon a wealth of theoretical and physical data. Equally important, however, are three additional chapters that deal with the general consequences of the stereoelectronic interactions that are associated with the basis of the anomeric effect. The remainder of the book is devoted to new areas of development in the topic-such as differentiation of the endo and exo anomeric interactions, specific analysis of the enthalpic component of anomeric effects, critical evaluation of the kinetics and reverse anomeric effects, discovery of a new substantial effect in second- and lower-row anomeric segments, and others. |
| conformational analysis organic chemistry: Introduction to Stereochemistry Torsten Schmiermund, 2021-06-07 Conformal, diastereomers, rotamers, tautomers, anomers: The multitude of terms used in stereochemistry quickly makes this subfield of chemistry confusing. In addition, there are different nomenclatures and different forms of representation (Fischer projection, Haworth ring formula, Newman projection). This essential deals with basic static stereochemistry and gives an overview of the different isomeric forms and nomenclatures. It is thus both a help and a reference book. This Springer essential is a translation of the original German 1st edition essentials, Einführung in die Stereochemie by Torsten Schmiermund, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. |
| conformational analysis organic chemistry: Tables of Spectral Data for Structure Determination of Organic Compounds Ernö Pretsch, T. Clerc, J. Seibl, W. Simon, 2013-06-29 Although numerical data are, in principle, universal, the compilations presented in this book are extensively annotated and interleaved with text. This translation of the second German edition has been prepared to facilitate the use of this work, with all its valuable detail, by the large community of English-speaking scientists. Translation has also provided an opportunity to correct and revise the text, and to update the nomenclature. Fortunately, spectroscopic data and their relationship with structure do not change much with time so one can predict that this book will, for a long period of time, continue to be very useful to organic chemists involved in the identification of organic compounds or the elucidation of their structure. Klaus Biemann Cambridge, MA, April 1983 Preface to the First German Edition Making use of the information provided by various spectroscopic tech niques has become a matter of routine for the analytically oriented organic chemist. Those who have graduated recently received extensive training in these techniques as part of the curriculum while their older colleagues learned to use these methods by necessity. One can, therefore, assume that chemists are well versed in the proper choice of the methods suitable for the solution of a particular problem and to translate the experimental data into structural information. |

| conformational analysis organic chemistry: Basic Concepts in Organic Stereochemistry Sunil Kumar Talapatra, Bani Talapatra, 2023-01-01 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. |
| conformational analysis organic chemistry: Introduction to Stereochemistry Andrew Clark, Russ Kitson, Nimesh Mistry, Paul Taylor, Matthew Taylor, Michael Lloyd, Caroline Akamune, 2023-01-17 CHEMISTRY STUDENT GUIDES. GUIDED BY STUDENTS Why did the drug thalidomide cause birth defects? What is the chemical difference between sucrose and lactose in your food? Stereochemistry holds the answer and is essential to the understanding of the chemistry of life. Stereochemistry is an important concept that often causes confusion amongst students when they learn it for the first time. Unlike most other areas of chemistry, it requires the chemist to visualise molecules in 3D, which can be difficult. In this book we deal with tricky concepts like conformation and configuration, how to represent them accurately and how to use the correct terms to describe them in both organic and inorganic chemistry. We involved students in the writing process to ensure we deal with areas that you find difficult, in an understandable language. With problems designed to focus on common errors and misconceptions, real life examples, and practical hands-on exercises coupled with visualisation tips, our intention is to give you the tools to become confident in stererochemistry. Complementing mainstream organic textbooks, or self-study, this book is for anyone who has struggled with describing alkenes as E or Z, assigning R and S absolute configurations, drawing Newman projections or chair representations of cyclohexanes, axial chirality, understanding the stereochemistry of octahedral metal complexes and indeed explaining complexities observed in NMR spectra. Chemistry Student Guides are written with current students involved at every stage, guiding the books towards the most challenging aspects of the topic. Student co-authors for Introduction to Stereochemistry are Caroline Akamune, Michael Lloyd and Matthew Taylor. |

| conformational analysis organic chemistry: Principles of Asymmetric Synthesis R.E. Gawley, J. Aubé, 1996-11-21 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 (more than 1300 references), the aim of this book is to present a detailed analysis of the factors that govern stereoselectivity in organic reactions. It is important to note that the references were each individually checked by the authors to verify relevance to the topics under discussion. The study of stereoselectivity has evolved from issues of diastereoselectivity, through auxiliary-based methods for the synthesis of enantiomerically pure compounds (diastereoselectivity followed by separation and auxiliary cleavage), to asymmetric catalysis. In the latter instance, enantiomers (not diastereomers) are the products, and highly selective reactions and modern purification techniques allow preparation - in a single step - of chiral substances in 99% ee for many reaction types. After an explanation of the basic physical-organic principles of stereoselectivity, the authors provide a detailed, annotated glossary of stereochemical terms. A chapter on Analytical Methods provides a critical overview of the most common methods for analysis of stereoisomers. The authors then follow the 'tried-and-true' format of grouping the material by reaction type. Thus, there are four chapters on carbon-carbon bond forming reactions (enolate alkylations, organometal additions to carbonyls, aldol and Michael reactions, and cycloadditions and rearrangements), one chapter on reductions and hydroborations (carbon-hydrogen bond forming reactions), and one on oxidations (carbon-oxygen and carbon-nitrogen bond forming reactions). Leading references are provided to natural product synthesis that have been accomplished using a given reaction as a key step. In addition to tables of examples that show high selectivity, a transition state analysis is presented to explain - to the current level of understanding - the stereoselectivity of each reaction. In one case (Cram's rule) the evolution of the current theory is detailed from its first tentative (1952) postulate to the current Felkin-Anh-Heathcock formalism. For other reactions, only the currently accepted rationale is presented. Examination of these rationales also exposes the weaknesses of current theories, in that they cannot always explain the experimental observations. These shortcomings provide a challenge for future mechanistic investigations. |

| conformational analysis organic chemistry: Is This Wi-Fi Organic? Dave Farina, 2021-03-30 How to separate facts from fake science in the Disinformation Age: “Cuts through the chaos . . . sure to keep you laughing while also keeping you thinking.” —Matt Candeias, PhD, author of In Defense of Plants We live in an era when scams, frauds, fake news, fake stories, fake science, and false narratives are everywhere. Fortunately, you don’t need a BS in Science to spot science BS. This guide from educator Dave Farina, aka YouTube’s Professor Dave, is a playful yet practical investigation of popular opinions and consumer trends that permeate our society. Shoppers insist on “organic” everything even if they’re unable to define the term. Healers and quantum mystics secure a foothold alongside science-based medicine in an unregulated and largely unchallenged landscape. Misleading marketing is used to sell you products and services that range from ineffectual to downright dangerous. With the knowledge gained from Dave Farina’s simple explanations of basic scientific principles, you can learn to spot misinformation and lies on the internet before they spot you. Learn the real science behind such semi-controversial subjects as drugs, vaccines, energy, and biotechnology—and most importantly, arm yourself with the critical-thinking skills everyone needs in a world filled with nonsense. “Scientific literacy is our best defense in an age of increasing disinformation.” —Kellie Gerardi, aerospace professional and author of Not Necessarily Rocket Science |
