Book Description :

This book provides an introduction to the chemistry of conjugate reactions, a group of reactions that constitute one of the most important classes of chemical reactions in organic synthesis. The book is organised in terms of the major classes of conjugate acceptors. Within each of these classes, the chemistry and applications of conjugate additions with several different categories of nucleophiles have been examined. Where several different nucleophiles achieve the same synthetic transformation, they are cross-referenced within the book and qualitative comparisons offered where appropriate. Examples of the use of conjugate additions in total synthesis of important molecules are included, with a special emphasis throughout the book on stereoselectivity. This will be a useful main text for graduate and postgraduate courses on conjugate addition reactions or the Michael reaction. It could also serve as a supplementary text for courses on topics such as the chemistry of organocopper reagents, enamines and carbanion chemistry.

Book Description :

Conjugate Addition Reactions in Organic Synthesis, second edition, provides an introduction to the chemistry of conjugate reactions, a group of reactions that constitute one of the most important classes of chemical reactions in organic synthesis. The book is organized according to class of acceptor rather than the class of nucleophile, which makes for easier synthetic problem solving. All aspects of conjugate addition reactions are covered, including theory, mechanism, catalysis, and total synthesis. Asymmetric processes are featured heavily, and there is emphasis on catalysis, given its importance in all aspects of organic synthesis today. Extensive examples in total synthesis illustrate how particular synthetic challenges are addressed and resolved with conjugate addition chemistry. The second edition features new coverage of acceptors and nucleophiles, as well as organocatalysis, gold catalysis, peptide catalysis, arene additions, and emerging areas such as biocatalytic methods and advances in mechanism theory. This book is an ideal reference for advanced undergraduates, post-graduates, researchers, and academics working in medicinal, pharmaceutical, polymer and industrial chemistry. Features a unique structure for this subject which enables readers to readily access information based on specific classes of conjugate acceptor Provides a thorough account of the latest thinking of the mechanistic basis of conjugate addition reactions and all the latest - and best - methods for achieving the highest selectivity in conjugate addition reactions Includes over 200 examples of total synthesis illustrating how particular synthetic challenges are addressed and resolved with conjugate addition chemistry Covers an up to date treatment of the latest aspects of conjugate addition reactions including inter alia, cascade reactions, organocatalysis and flow chemistry

Book Description :

During the miners' strike in the 1980s, a worker is killed in the striking coalfields of Wales. Some months later, a government minister thought to be connected with the death is also shot. Lewis Redfern—once a radical but now a political analyst and journalist—pursues the sniper, a lonely hunt that leads him through an imbroglio of civil service leaks to a secret organization: a source of insurrection far more powerful than anyone could have suspected known as the Volunteers. In this fast-paced narrative of espionage and intrigue, Redfern, through his obsessive pursuit of justice, finally encounters the truth about himself as the novel discusses the conflict between moral choice and political loyalty.

Book Description :

This English edition of a best-selling and award-winning German textbook Reaction Mechanisms: Organic Reactions · Stereochemistry · Modern Synthetic Methods is aimed at those who desire to learn organic chemistry through an approach that is facile to understand and easily committed to memory. Michael Harmata, Norman Rabjohn Distinguished Professor of Organic Chemistry (University of Missouri) surveyed the accuracy of the translation, made certain contributions, and above all adapted its rationalizations to those prevalent in the organic chemistry community in the English-speaking world. Throughout the book fundamental and advanced reaction mechanisms are presented with meticulous precision. The systematic use of red "electron-pushing arrows" allows students to follow each transformation elementary step by elementary step. Mechanisms are not only presented in the traditional contexts of rate laws and substituent effects but, whenever possible, are illustrated using practical, useful and state-of-the-art reactions. The abundance of stereoselective reactions included in the treatise makes the reader familiar with key concepts of stereochemistry. The fundamental topics of the book address the needs of upper-level undergraduate students, while its advanced sections are intended for graduate-level audiences. Accordingly, this book is an essential learning tool for students and a unique addition to the reference desk of practicing organic chemists, who as life-long learners desire to keep abreast of both fundamental and applied aspects of our science. In addition, it will well serve ambitious students in chemistry-related fields such as biochemistry, medicinal chemistry and pharmaceutical chemistry. From the reviews: "Professor Bruckner has further refined his already masterful synthetic organic chemistry classic; the additions are seamless and the text retains the magnificent clarity, rigour and precision which were the hallmark of previous editions. The strength of the book stems from Professor Bruckner’s ability to provide lucid explanations based on a deep understanding of physical organic chemistry and to limit discussion to very carefully selected reaction classes illuminated by exquisitely pertinent examples, often from the recent literature. The panoply of organic synthesis is analysed and dissected according to fundamental structural, orbital, kinetic and thermodynamic principles with an effortless coherence that yields great insight and never over-simplifies. The perfect source text for advanced Undergraduate and Masters/PhD students who want to understand, in depth, the art of synthesis ." Alan C. Spivey, Imperial College London "Bruckner’s ‘Organic Mechanisms’ accurately reflects the way practicing organic chemists think and speak about organic reactions. The figures are beautifully drawn and show the way organic chemists graphically depict reactions. It uses a combination of basic valence bond pictures with more sophisticated molecular orbital treatments. It handles mechanisms both from the "electron pushing perspective" and from a kinetic and energetic view. The book will be very useful to new US graduate students and will help bring them to the level of sophistication needed to be serious researchers in organic chemistry." Charles P. Casey, University of Wisconsin-Madison "This is an excellent advanced organic chemistry textbook that provides a key resource for students and teachers alike." Mark Rizzacasa, University of Melbourne, Australia.

Book Description :

This book, unique in its field, is a comprehensive description of all the methodologies reported for carrying out conjugate addition reactions in a stereoselective way, using small chiral organic molecules as catalysts (organocatalysts). In the last 3-4 years, this has been a rapidly growing field in organic chemistry, and many papers have appeared reporting excellent protocols for carrying out these highly efficient transformations that compete well with other classical approachse using transition metal catalysts. A particularly attractive feature of this transformation relies upon the fact that the conjugate addition (Michael and Hetero-Michael reactions) is an extraoridinarily effective means to initiate cascade processes which result in the formation of complex molecules from very small and simple starting blocks. The book, written by noted experts, covers all recent advances in this not topic, and provides a good state-of-the-art review for organic chemists working in this field and all those who wish to start projects in this area. The Series is intended to provide an accessible reference for postgraduates and industrialists working in the field of catalysis and its applications. Books will be produced either as monographs or reference handbooks. The Series will cover research developments and applications of catalysis, in both academia and industry.

Book Description :

This thesis is concerned with the asymmetric conjugate addition reactions of a range of chiral nucloeophiles. Chapter 1 introduces the conjugate addition reaction as a valuable carbon-carbon and carbon-heteroatom bond forming reaction in organic chemistry, and explores the asymmet- ric conjugate addition of a range of chiral and achiral carbon and nitrogen nucleophiles to a range of acceptors. Chapter 2 explores the use of the N-benzyl-N-([alpha]-methylbenzyl)amino group as a chi- ral auxiliary, by employing the attempted conjugate additions of both N-benzyl-N-([alpha]- methylbenzyl)hydrazine and N -benzyl-N -([alpha]-methylbenzyl)hydroxylamine as chiral ammo- nia and water equivalents respectively. Chapter 3 describes the asymmetric and stereoselective preparation of a range of 4,4- disubstituted isoxazolidin-5-ones from the conjugate addition of lithium (S)-N-tert-butyl- dimethylsilyloxy-N -([alpha]-methylbenzyl)amide. The isoxazolidin-5-ones are then globally de- protected via hydrogenolysis, giving rise to the corresponding [beta]2,2,3-amino acids. Chapter 4 focuses on the development of a protocol to effect the conjugate addition of a chiral aniline equivalent. The scope of the reaction is delineated by varying both the nu- cleophile and the [alpha],[beta]-unsaturated ester. Finally, cyclisation of the [beta]-N-arylamino esters to the corresponding tetrahydroquinolines is explored, and an application to the synthesis of the natural product (-)-angustureine is presented. Chapter 5 contains full experimental procedures and characterisation data for all com- pounds synthesised in Chapters 2, 3 and 4.
