Anionic Annulations in Organic Synthesis: A Versatile and Prolific Class of Ring-Forming Reactions is a comprehensive review of the best annulations for the construction of cyclic structures and their applications in the total synthesis of functional molecules. The reactions described in the work are particularly useful for the synthesis of polyoxygenated polycyclic compounds, including tetracyclines, angucyclines, uncialamycins, and lignans, among other compounds. Included in detail are the Hauser, Robinson, Sammes and Meyers annulations, all of which can be effectively used to construct substrates with complex molecular structures. This work provides the tools to master anionic organic chemistry, ortho-lithiation, lateral lithaition/metalation and organic selectivity issues, like chemoselectivity, regioselectivity and stereoselectivity. This book is a valuable resource for organic chemists, researchers and students seeking a complete and detailed understanding of anionic annulations. Provides a comprehensive review of anionic cyclization for chemical construction of a variety of cyclic scaffolds involved in many kinds of biologically active natural products and pharmaceutical drugs Serves as a useful tool to academic and industrial researchers working on the synthesis of cyclic compounds as their targets Includes many examples of anionic annulations and practical information on how to use them in research and industry Features anionic annulations that are particularly useful for the synthesis of polyoxygenated polycyclic compounds, including tetracyclines, angucyclines, uncialamycins and lignans

This three-volume set represents the first comprehensive coverage of the rapidly expanding field of Lewis base catalysis that has attracted enormous attention in recent years. Lewis base catalysis is a conceptually novel paradigm that encompasses an extremely wide variety of preparatively useful transformations and is particularly effective for enantioselectively constructing new stereogenic centers. As electron-pair donors, Lewis bases can influence the rate and stereochemical course of myriad synthetic organic reactions. The book presents the conceptual/mechanistic principles that underlie Lewis base catalysis, and then builds upon that foundation with a thorough presentation of many different reaction types. And last but not least, the editors, Prof. Edwin Vedejs and Prof. Scott E. Denmark, are without doubt the leaders in this emerging field and have compiled high quality contributions from an impressive collection of international experts.

From Boron Trifluoride to Zinc, the 52 most widely used reagents in organic synthesis are described in this unique desktop reference for every organic chemist. The list of reagents contains classics such as N-Bromosuccinimide (NBS) and Trifluoromethanesulfonic Acid side by side with recently developed ones like Pinacolborane and Tetra-n-propylammonium Perruthenate (TPAP). For each reagent, a concise article provides a brief description of all important reactions for which the reagent is being used, including yields and reaction conditions, an overview of the physical properties of the reagent, its storage conditions, safe handling, laboratory synthesis and purification methods. Advantages and disadvantages of the reagent compared to alternative synthesis methods are also discussed. Reagents have been hand-picked from among the 5000 reagents contained in EROS, the Encyclopedia of Reagents for Organic Synthesis. Every organic chemist should be familiar with these key reagents that can make almost every reaction work.

Over the last three decades the importance of organosiliconchemistry has greatly increased because it has opened a number ofnew synthetic strategies. Silicon reagents are usually low-cost,versatile and allow a wide range of reactions. This is the firstHandbook to compile essential Silicon containing reagents and makesuse of the leading reagent database e-EROS. Another hotvolume in the series Handbooks of Reagents for OrganicSynthesis, this is a must-have resource for all syntheticchemists working in drug development and medicinal chemistry. For the selection the Editor focussed on three key syntheticapproaches with the greatest impact: 1. Use of silicon as a 'temporary tether' by unifying a reactivepair of functional groups and taking advantage of theirtemplate-biased intramolecular cyclization. 2. The specific use of the silane functionality as a heterot-butyl group, often colloquially referred to as the use ofsilicon as a 'fat proton'. 3. The use of the Brook rearrangement as an 'anion relaystratagem'. A new feature in this Handbook is the reagent finder, analphabetically organized lookup table arranged by organicfunctionality and specific structure of the silicon atom to whichit is bound.

Provides the background, tools, and models required to understand organic synthesis and plan chemical reactions more efficiently Knowledge of physical chemistry is essential for achieving successful chemical reactions in organic chemistry. Chemists must be competent in a range of areas to understand organic synthesis. Organic Chemistry provides the methods, models, and tools necessary to fully comprehend organic reactions. Written by two internationally recognized experts in the field, this much-needed textbook fills a gap in current literature on physical organic chemistry. Rigorous yet straightforward chapters first examine chemical equilibria, thermodynamics, reaction rates and mechanisms, and molecular orbital theory, providing readers with a strong foundation in physical organic chemistry. Subsequent chapters demonstrate various reactions involving organic, organometallic, and biochemical reactants and catalysts. Throughout the text, numerous questions and exercises, over 800 in total, help readers strengthen their comprehension of the subject and highlight key points of learning. The companion Organic Chemistry Workbook contains complete references and answers to every question in this text. A much-needed resource for students and working chemists alike, this text: -Presents models that establish if a reaction is possible, estimate how long it will take, and determine its properties -Describes reactions with broad practical value in synthesis and biology, such as C-C-coupling reactions, pericyclic reactions, and catalytic reactions -Enables readers to plan chemical reactions more efficiently -Features clear illustrations, figures, and tables -With a Foreword by Nobel Prize Laureate Robert H. Grubbs Organic Chemistry: Theory, Reactivity, and Mechanisms in Modern Synthesis is an ideal textbook for students and instructors of chemistry, and a valuable work of reference for organic chemists, physical chemists, and chemical engineers.

From reviews of previous volumes: "Essential for chemistry collections at the university and research levels." -New York Public Library "Highly recommended . . . lots of succinct, practical information on recent developments . . . in a format that is easy to use. The reagents are taken up in alphabetical order (common usage names, not CAS indexing codenames), sometimes several to a page, sometimes several pages to a reagent. One can expect to find how to make the reagent (in loose terms), or where it can be bought, what it is good for, and where to seek complete details. As with previous volumes, one can profit from just browsing, even if one does not feel a need to look up any particular subject. It is thus a secondary function of the book to help one keep abreast of the field, and it would be a rare chemist who would not learn something new and useful from a casual perusal of the pages." -Journal of the American Chemical Society This highly successful series has provided generations of professional chemists with a comprehensive, up-to-date look at the reagent literature. Now the series continues with its concise descriptions, good structural formulas, and selected examples of application, providing references to new reagents as well as to reagents included in previous volumes. This volume covers the synthetic literature from 2005 to 2006. CONTENTS: General abbreviations Reference abbreviations Reagents Author index Subject index
