Book Description
Activated Metals in Organic Synthesis discusses fundamental principles of the generation of activated, highly reactive metals, and their applications in organic synthesis. Following an introductory chapter on basic forms of metals the chapters in Part 1 are devoted to common strategies utilized for the preparation of active metals. These strategies include vaporization and subsequent co-condensation of metal atoms, in addition to depassivating methods employed commonly in laboratory syntheses. Chapters in Part 2 discuss relevant organic transformations in which metal activation plays a crucial role. Specific topics covered include metal-induced reductive methods; pinacolic, Reformatsky-, and Barbier-type reactions; McMurry ketone-olefin coupling; and the Bernet-Vasella reaction. Each chapter is followed by literature citations ranging from specific references to significant reviews. Many structural formulas are provided, making it easy to follow each synthesis. The book will be an important reference for students, organic chemists, and researchers in all areas of organometallic chemistry.

Book Description
Titanium has been used to perform many kinds of reactions in organic and inorganic chemistry. The present book is concerned primarily with a new development in titanium chemistry which is useful in organic synthesis. In 1979/80 it was discovered that the titanation of classical carbanions using C1TiX leads to species with reduced basicity and reactivity. This increases 3 chemo-, regio-and stereo selectivity in reactions with organic compounds such as aldehydes, ketones and alkyl halides. Many new examples have been reported in recent times. Since the nature of the ligand X at titanium can be widely varied, the electronic and steric nature of the reagents is easily controlled. This helps in predicting the stereochemical outcome of many of the C-C bond forming reactions, but the trial and error method is still necessary in other cases. One of the ultimate objectives of chemistry is to understand correlations between structure and reactivity. Although this goal has not been reached in the area of organotitanium chemistry, appreciable progress has been made. A great deal of physical and computational data of organotitanium compounds described in the current and older literature (e. g. , Ziegler-Natta type catalysts) has been reported by polymer, inorganic and theoretical chemists. It is summarized in Chapter 2 of this book, because some aspects are useful in understanding reactivity and selectivity of organo titanium compounds in organic synthesis as described in the chapters which follow.

Book Description
Lewis acids provide inexpensive access to elaborated molecules obtained with high selectivities (regio-, stereo-, and enantioselectivity). Lewis Acids and Selectivity in Organic Synthesis is the first book to deal with these new and promising roles of Lewis acids. The book begins with general considerations on Lewis acids and a description of Lewis acid-carbonyl complexes, which are involved in most of the reactions described: ene reactions, allylsilane and allyltin addition to carbonyl compounds, addition of nucleophiles to acetals, conjugated addition of allylsilanes and allyltins to unsaturated carbonyl compounds (Sakurai reaction), and Diels-Alder reaction. Subsequent chapters examine these issue in detail, with special attention given to the way Lewis acids induce diastereo- and enantioselectivity. The extensive use of schemes (approximately 1000) ensures rapid visual uptake of the information. Lewis Acids and Selectivity in Organic Synthesis serves as a valuable source of information for all who face the challenge of selectivity in organic synthesis.

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
Template-controlled reactions allow the synthesis of complex molecules which would hardly be achievable through classical methods. This handbook offers authoratative information on how noncovalent and covalent templates can be effectively applied to control reaction rates as well as regio- and stereoselectivity. From the concepts of template control such as molecular imprinting, self-replication, and reversible tether-directed remote functionalization, the reader is led to template-based ring-closing reactions, oligomerizations, and multiple functionalizations and their application in the synthesis of supramolecular scaffolds and natural products. The editors and authors (J. F. Stoddart, G. Wulf, D. Lynn, R. Breslow. F. Diederich, just to name a few ) , all internationally recognized experts in their area, succeeded in presenting the manifold aspects of template-controlled synthesis in a didactic way, making this methodology accessible to a broad readership of organic synthetic chemists. Well-selected, reliable key experimental protocols and an up-to-date reference list underline the practical approach of this valuable handbook. Being the first book of its kind, it will serve as a pacemaker and stimulate future research.
