Stereoelectronic Effects by Anthony John Kirby Pdf

Stereoelectronic effects control the way molecules are put together an d account for the "rules of engagement" which operate when molecules m eet and react. Understanding these effects is the key to understanding molecular behavior, since the same basic three-dimensional interactio ns are responsible for both structure and reactivity. This concise and very accessible volume provides a comprehensive, intentionally non-ma thematical coverage of stereochemistry, along with an in-depth discuss ion of the main classes of organic reactions, promoting a logical and simple way of thinking about chemistry.

The Anomeric Effect by Eusebio Juaristi,Gabriel Cuevas Pdf

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.

Electrostatic and Stereoelectronic Effects in Carbohydrate Chemistry by Momcilo Miljkovic Pdf

The book deals with polar effects in carbohydrates and how these effects control the stereochemistry of carbohydrate reactions. This is important for understanding the mechanisms of certain carbohydrate reactions, including enzymatic reactions such as glycosidases, a very important group of enzymes in living matter. It is also very useful for synthetic carbohydrate chemists who would like to synthesize stereoselectively certain classes of carbohydrates. This book will be a very important source of information for practicing synthetic carbohydrate chemists. The book will also be helpful for organic chemists, or for those studying glycobiology.

Stereochemistry by Anil V. Karnik,Mohammed Hasan Pdf

Stereochemistry: A Three-Dimensional Insight draws on the knowledge of its expert authors, providing a systematic treatment on the fundamental aspects of stereochemistry, covering conformational aspects, configurational aspects, effects of bulkiness, stereoelectronic effects on properties of molecules, and the genesis of enantiomerism, among other topics. Visuals and exercises are included to consolidate the principles learned, and the contents are carefully structured to prepare readers for predicting and organizing reaction components to obtain desired stereochemical outcomes. This book is an indispensable guide for all those exploring stereochemistry within their work. The principles of stereochemistry are fundamental to understanding chemical behavior and can provide insights into a whole range of problems, from unusual selectivity and unexpected behaviors, to abnormally fast reactions and surprising biochemical preferences. However, understanding and exploring these 3D effects can be difficult within a 2D medium. This book has been designed to address this problem, providing foundational guidance on the principles and applications of stereochemistry that are fully supported by multimedia visuals. Combines foundational concepts and definitions with examples of stereochemistry in practice Highlights the conformational and configurational impact of atomic arrangement on chemical behavior Outlines methods of analysis Provides practical exercises and detailed multimedia visuals to support learning

Side Reactions in Organic Synthesis by Florencio Zaragoza Dörwald Pdf

Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure-reactivity relationship of organic compounds. This textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success-rate. A must for every graduate student but also for every chemist in industry and academia. Contents: 1 Organic Synthesis: General Remarks 2 Stereoelectronic Effects and Reactivity 3 The Stability of Organic Compounds 4 Aliphatic Nucleophilic Substitutions: Problematic Electrophiles 5 The Alkylation of Carbanions 6 The Alkylation of Heteroatoms 7 The Acylation of Heteroatoms 8 Palladium-Catalyzed C-C Bond Formation 9 Cyclizations 10 Monofunctionalization of Symmetric Difunctional Substrates

Pericyclic Reactions by Ian Fleming Pdf

The renowned Oxford Chemistry Primer series, which provides focused introductions to a range of important topics in chemistry, has been refreshed and updated to suit the needs of today's students, lecturers, and postgraduate researchers. The rigorous, yet accessible, treatment of each subjectarea is ideal for those wanting a primer in a given topic to prepare them for more advanced study or research. Moreover, cutting-edge examples and applications throughout the texts show the relevance of the chemistry being described to current research and industry.Learning features provided in the primers, including questions at the end of every chapter and interactive online MCQs, encourage active learning and promote understanding. Furthermore, frequent diagrams, margin notes, further reading, and glossary definitions all help to enhance a student'sunderstanding of these essential areas of chemistry.Pericyclic reactions constitute a major strand of organic chemistry, including such commercially important synthetic reactions as the Diels-Alder reaction. Reactions such as these are characterised by their predictable stereochemistry and cyclic transition structures. This primer reviews thesereactions, explaining their theoretical basis via correlation diagrams, and showing students how to recognise the different types of pericyclic reaction, their mechanisms, and applications to organic synthesis.

The Art of Writing Reasonable Organic Reaction Mechanisms by Robert B. Grossman Pdf

Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and "common error alerts" are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set.
