Book Description
Heterogeneous Enantioselective Hydrogenation: Theory and Practice reviews the development of enantioselective hydrogenation reaction catalysts. It looks at the first relatively ineffective catalysts right through to modern highly effective enantioselective catalytic systems, comparable in their efficiency to chiral metal complexes and enzymatic systems. The book begins with a summary of the first work on heterogeneous metal catalysts, which showed only the principal possibilities of enantioselective reactions. It then elaborates on metal catalysts which have enantioselectivities close to 100%. Finally, the practical utilization of chiral catalytic systems in processes of hydrogenation is described. The alpha- and beta-hydroxy carboxylic acid esters produced are precursors for manufacturing many synthones used for medicines as well as for monomers used for biodegradable polyesters, both of which have important practical applications. The volume summarizes more than 800 scientific papers in the field of enantioselective catalytic hydrogenation reactions, mainly those using heterogeneous metal catalysts. It provides detailed explanations of special techniques for the preparation of effective dissymmetric catalysts which provide highly efficient catalytic systems.

Book Description
Asymmetric Hydrogenation and Transfer Hydrogenation Discover the latest developments in homogeneous asymmetric (transfer) hydrogenation with this up-to-date resource Asymmetric Hydrogenation and Transfer Hydrogenation delivers a current and cutting-edge investigation of homogenous asymmetric hydrogenation and transfer hydrogenation reactions of prochiral substrates by using organometallic catalysts (like ruthenium, rhodium, iridium, iron, and copper) and organic catalysts. Distinguished researchers and editors Virginie Ratovelomanana-Vidal and Phannarath Phansavath also offer readers a comprehensive walkthrough of substituted ketones through dynamic kinetic resolution, as well a presentation of the mechanisms and application of asymmetric hydrogenation reactions to the synthesis of biologically relevant compounds. The book comprehensively details its complex subject matter clearly and plainly and covers everything from catalyst development and reactions to mechanisms and applications in academia and industry. The papers included within come from many of the leading voices in their respective fields and represent the newest and best research available today. Compiled for researchers and private-industry chemists alike, Asymmetric Hydrogenation and Transfer Hydrogenation also discusses a wide variety of other topics like: A discussion of the development of chiral metal catalysts for asymmetric transfer hydrogenation Several examinations of asymmetric transfer hydrogenation of a variety of chemical groups, including ketones, aryl and heteroaryl ketones, substituted ketones, and heteroaromatic compounds, alkenes, and imines An exploration of the mechanism of asymmetric hydrogenation and continuous flow asymmetric hydrogenation A full and thorough treatment of the industrial applications of asymmetric hydrogenation Perfect for catalytic chemists, chemists working on or with organometallics, organic chemists, natural product chemists, pharmaceutical chemists, medicinal chemists, and industrial chemists, Asymmetric Hydrogenation and Transfer Hydrogenation also belongs on the bookshelves of research and university institutes and libraries who wish to expand their selection on a topic fundamental to organic synthesis.

Book Description
This book covers advances in the methods of catalytic asymmetric synthesis and their applications. Coverage moves from new materials and technologies to homogeneous metal-free catalysts and homogeneous metal catalysts. The applications of several methodologies for the synthesis of biologically active molecules are discussed. Part I addresses recent advances in new materials and technologies such as supported catalysts, supports, self-supported catalysts, chiral ionic liquids, supercritical fluids, flow reactors and microwaves related to asymmetric catalysis. Part II covers advances and milestones in organocatalytic, enzymatic and metal-based mediated asymmetric synthesis, including applications for the synthesis of biologically active molecules. Written by leading international experts, this book consists of 16 chapters with 2000 References and illustrations of 560 schemes and figures.

Book Description
The domain of catalytic hydrogenation continues to grow fast, reflecting the wide range of chemical applications that can be enhanced by the easy use of molecular hydrogen. The advances in characterization techniques and their application have improved our understanding of the catalytic processes and mechanisms occurring in both homogeneous and heterogeneous catalysis. The aim of this volume, although not exhaustive, is to provide a general overview of new progress of the hydrogenation reactions. This volume comprises a series of various contributions, as reviews or original articles, treating heterogeneously and homogeneously catalyzed hydrogenation reactions. It is composed of three parts: hydrogenation reactions in fine organic chemistry, hydrogenation reactions in environmental chemistry and renewable energy, and special topics in hydrogenation.

Book Description
The field of asymmetric catalysis is currently one of the hottest areas in chemistry. This unique book focuses on the mechanism of enantioselectivity in asymmetric catalysis, rather than asymmetric catalysis from the synthetic view. It describes reliable, experimentally and computationally supported mechanisms, and discusses the danger of so-called "plausible" or "accepted" mechanisms leading to wrong conclusions. It draws parallels to enzymatic catalysis in biochemistry, and examines in detail the physico-chemical aspects of enantioselective catalysis.
