Book Description
Bio-organic Chemistry has corne of age - the sign of this is the start of a new series of Lecture Notes that are the product and substrate of spreading this line of modern knowledge among graduate students and research workers in such fields as mechanistic biochemistry, bio mimetic organic chemistry, biotechnological application of enzymology, to name only a few examples of how many frontiers are opened and borders lifted - just at. the time when the demand for a'''Synthetic Biology" and "Molecular Biotechnology" is increasing - fields that have been neglected for (too) long a time by "classical" chemists in curricula and imagination. We hope that through this first volume, which pOints in the several directions mentioned above, the profile of the undertaking will become clear and that it will find resonance among the scientific community interested in the thoughtful application of chemical and physical con cepts to biochemical and molecular-biological problems.

Book Description
Chemistry and Biochemistry of Flavoenzymes summarizes the present knowledge of the chemical and physical properties of free flavin, modified flavins occurring in nature, and deazaflavin. This information forms the fundamental basis for understanding the catalytic properties of flavoenzymes. Flavoproteins involved in transport, electron transfer, oxidation, dehydrogenation and hydroxylation reactions are discussed with respect to their biochemical and biophysical properties. The book presents the catalytic mechanisms of the flavoproteins in detail and, where available, three-dimensional structures and molecular biology data are included. The medical aspects of free and protein-bound flavin are also briefly discussed. Chemistry and Biochemistry of Flavoenzymes is an essential reference source for chemists, biochemists, toxicologists, biologists, pharmacologists, and researchers in the pharmaceutical industry.

Book Description
"Nitroalkenes have often been referred to as "synthetic chameleons" owing to their reactivity, synthetic utility and biological significance. In the last two decades, the reactivity of nitroalkenes as substrates in diverse catalytic asymmetric transformations has been of tremendous interest. This is due to the powerful electron withdrawing and co-ordinating ability of the nitro group and the amenability of the nitro group to undergo a wide variety of synthetic transformations. Although numerous original articles and reviews have appeared in the literature, a monograph providing comprehensive coverage of this topic was conspicuous by its absence. In the light of the above, this book features: A systematic, up-to-date, in-depth and well organized compilation, spread over twelve chapters, of various catalytic asymmetric reactions of nitroalkenes with diverse substrates reported till date Wide coverage of reactions such as Michael additions, Friedel-Crafts reactions, cycloadditions, asymmetric reductions, multi-component and cascade reactions as well as other miscellaneous reactions Various chiral organo-, metal- and even bio-catalysts involved in the stereoselective synthesis of multi-functional adducts via catalytic asymmetric reactions of nitroalkenes Schemes and figures detailing all the reagents, reaction conditions and product profile Mechanistic details, including transition state models, which will be useful for effective catalytic design This book will be an invaluable resource for those who are working in the area of asymmetric catalysis and synthetic methodologies"--

Book Description
Stereochemistry and Organic Reactions: Conformation, Configuration, Stereoelectronic Effects and Asymmetric Synthesis provides coverage on the stereochemistry of reactions of all mechanistic types, ranging from ionic, pericyclic and transition metal-catalyzed to radical and photochemical. Chapters cover acyclic molecules, cyclic molecules, the stereochemistry of organic reactions, the perturbation molecular orbital theory for the origin of stereoelectronic effects, and an introduction to the principles of stereoselectivity and hierarchical levels of asymmetric synthesis. Each chapter includes problems that reinforce main themes, making it valuable to students, teachers and researchers working in organic, biological and medicinal chemistry, as well as biologists, pharmacologists, polymer chemists and chemists. Presents a holistic and unified approach to stereochemical understanding and predictions, covering reactions of all mechanistic classes Includes two background chapters on perturbation theory and stereoselective principles, along with asymmetric designs Features novel rules and mnemonics to delineate product stereochemistry Includes up-to-date coverage with over 1300 selective references

Book Description
The rate of advance in areas of science is seldom constant. Usually certain fields effloresce with activity because of the ~ealization that solutions are possible to long standing important problems. So it is now with asymmetric catalysis, a field which promises to change profoundly the strategic thinking of synthetic chemists. As this Report will show, reagents which can induce catalytic enantiocontrol of chemical transformations could represent the ultimate synthetic method. Nearly all synthetic strategies of complex molecules involve steps which require enantiocontrol and, in many cases, a specific catalytic transformation embodying enan tiocontrol has enormous advantages in terms of the rate and economy of the reaction. Because asymmetric catalysis is in a formative stage, workers with different backgrounds have joined the field. This Workshop had representatives with organometallic, organic, structural, kinetic, enzymatic, microbiological and industrial backgrounds. Each had his own perspective and this Report represents a consensus of this group of eleven people. The result is probably as compre hensive and balanced a view of the subject as is possible at present. It is hoped that those who have until now had but a glancing interest in asymmetric catalysis will find this Report a useful indication of its present state. We believe that asymmetric catalysis will have an increasing impact on the development of chemistry and will eventually dominate much of synthetic and industrial chemistry.

Book Description
For the first time, the whole field of organoboronic acids is presented in one comprehensive handbook. Professor Dennis Hall, a rising star within the community, covers all aspects of this important substance class, including applications in chemistry, biology and medicine. Starting with an introduction to the structure, properties, and preparation of boronic acid derivatives, together with an overview of their reactions and applications, the book goes on to look at metal-catalyzed borylation of alkanes and arenas, coupling reactions and rhodium-catalyzed additions of boronic acids to alkenes and carbonyl compounds. There follows chapters on copper-promoted C-O and C-N cross-coupling of boronic acids, recent applications in organic synthesis, as well as alpha-haloalkylboronic esters in asymmetric synthesis. Later sections deal with cycloadditions, organoboronic acids, oxazaborolidines as asymmetric inducers, and boronic acid based receptors and sensors. The whole is rounded off with experimental procedures, making this invaluable reading for organic, catalytic and medicinal chemists, as well as those working in organometallics.
