Synthesis is at the core of organic chemistry. In order for compounds to be studied—be it as drugs, materials, or because of their physical properties— they have to be prepared, often in multistep synthetic sequences. Thus, the target compound is at the outset of synthesis planning. Synthesis involves creating the target compound from smaller, readily available building blocks. Immediately, questions arise: From which bui- ing blocks? In which sequence? By which reactions? Nature creates many highly complex “natural products” via reaction cascades, in which an asso- ment of starting compounds present within the cell is transformed by speci c (for each target structure) combinations of modular enzymes in speci c - quences into the target compounds [1, 2]. To mimic this ef ciency is the dream of an ideal synthesis [2]. However, we are at present so far from - alising such a “one-pot” operation that actual synthesis has to be achieved via a sequence of individual discrete steps. Thus, we are left with the task of planning each synthesis individually in an optimal fashion. Synthesis planning must be conducted with regard for certain speci - tions, some of which are due to the structure of the target molecule, and some of which relate to external parameters such as costs, environmental compatibility, or novelty. We will not consider these external aspects in this context. Planning of a synthesis is based on a pool of information regarding chemical reactions that can be executed reliably and in high chemical yield.

Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.

Organic Synthesis, Fourth Edition, provides a reaction-based approach to this important branch of organic chemistry. Updated and accessible, this eagerly-awaited revision offers a comprehensive foundation for graduate students coming from disparate backgrounds and knowledge levels, to provide them with critical working knowledge of basic reactions, stereochemistry and conformational principles. This reliable resource uniquely incorporates molecular modeling content, problems, and visualizations, and includes reaction examples and homework problems drawn from the latest in the current literature. In the Fourth Edition, the organization of the book has been improved to better serve students and professors and accommodate important updates in the field. The first chapter reviews basic retrosynthesis, conformations and stereochemistry. The next three chapters provide an introduction to and a review of functional group exchange reactions; these are followed by chapters reviewing protecting groups, oxidation and reduction reactions and reagents, hydroboration, selectivity in reactions. A separate chapter discusses strategies of organic synthesis, and he book then delves deeper in teaching the reactions required to actually complete a synthesis. Carbon-carbon bond formation reactions using both nucleophilic carbon reactions are presented, and then electrophilic carbon reactions, followed by pericyclic reactions and radical and carbene reactions. The important organometallic reactions have been consolidated into a single chapter. Finally, the chapter on combinatorial chemistry has been removed from the strategies chapter and placed in a separate chapter, along with valuable and forward-looking content on green organic chemistry, process chemistry and continuous flow chemistry.

Originally published in Germany in 1968, this first comprehensive and critical survey of Le Corbusier's life and work soon became the standard text on the architect and polymath. French, Spanish, English, Japanese and Korean editions followed, but the book has now been out of print for almost two decades. In the meantime, Le Corbusier's archives in Paris have become available for research, resulting in an avalanche of scholarship. Von Moos' critical take and the basic criteria by which the subject is organized and historicized remain surprisingly pertinent in the context of this recent jungle of Corbusier studies. This new, completely revised edition is based on the 1979 version published in English by the MIT Press but offers a substantially updated body of illustrations. Each of the seven chapters is supplemented by a critical survey of recent scholarship on the respective issues. An updated edition of this acclaimed book, an essential read for students of architecture and architectural history.

Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.

Organic Synthesis: Strategy and Control is the long-awaited sequel to Stuart Warren's bestseller Organic Synthesis: The Disconnection Approach, which looked at the planning behind the synthesis of compounds. This unique book now provides a comprehensive, practical account of the key concepts involved in synthesising compounds and focuses on putting the planning into practice. The two themes of the book are strategy and control: solving problems either by finding an alternative strategy or by controlling any established strategy to make it work. The book is divided into five sections that deal with selectivity, carbon-carbon single bonds, carbon-carbon double bonds, stereochemistry and functional group strategy. * A comprehensive, practical account of the key concepts involved in synthesising compounds * Takes a mechanistic approach, which explains reactions and gives guidelines on how reactions might behave in different situations * Focuses on reactions that really work rather than those with limited application * Contains extensive, up-to-date references in each chapter Students and professional chemists familiar with Organic Synthesis: The Disconnection Approach will enjoy the leap into a book designed for chemists at the coalface of organic synthesis.

This book is a continuation of authors' previous six books — Understanding Advanced Physical Inorganic Chemistry, Understanding Advanced Organic and Analytical Chemistry, Understanding Advanced Chemistry Through Problem Solving Vol. I & II, Understanding Basic Chemistry and Understanding Basic Chemistry Through Problem Solving, retaining the main refutational characteristics of the previous books with the strategic inclusion of think-aloud questions to promote conceptual understanding during an experimental planning. These essential questions would make learners aware of the rationale behind each procedural step, the amount of chemical used and types of apparatus that are appropriate for the experiment.The book provides a fundamental important scaffolding to aid students to create their own understanding of how to plan an experiment based on the given reagent and apparatus. It guides the students in integrating the various concepts that they have learnt into a coherent and meaningful conceptual network during experimental planning.Existing A-level or IB guidebooks generally introduce concepts in a matter-of-fact manner. This book adds a unique pedagogical edge which few can rival. This book is essential and useful in order for students to be adequately prepared for their high stake examinations.
