With a foreword from leading organic chemist Professor Paul Wender, this book collects the major developments reported in the past thirty years in the field of enantioselective reactions promoted by chiral cobalt catalysts, illustrating the power of these green catalysts to provide all types of organic reactions from the basic to completely novel methodologies. The search for new methodologies to prepare optically pure products is one of the most active areas of research in organic synthesis. Of the methods available for preparing chiral compounds, catalytic asymmetric synthesis has attracted the most attention. In particular, asymmetric transition-metal catalysis is a powerful tool for performing reactions in a highly enantioselective fashion. Efforts to develop new asymmetric transformations have previously focused on the use of rare metals such as titanium, palladium, iridium and gold. However, the ever-growing need for environmentally friendly catalytic processes has prompted chemists to focus on the more abundant and less toxic first-row transition metals, such as cobalt, to develop new catalytic systems. The ability of cobalt catalysts to adopt unexpected reaction pathways has led to an impressive number of enantioselective cobalt-promoted transformations being developed over the past three decades. These have included the synthesis of many different types of products, often under relatively mild conditions and with remarkable enantioselectivities. This book is a useful reference resource for chemists, both academic and industrial, working in organic synthesis and interested in greener or more economical catalytic alternatives.

Introduces an innovative and outstanding tool for the easy synthesis of complex chiral structures in a single step Covering all of the literature since the beginning of 2006, this must-have book for chemists collects the major progress in the field of enantioselective one-, two-, and multicomponent domino reactions promoted by chiral metal catalysts. It clearly illustrates how enantioselective metal-catalyzed processes constitute outstanding tools for the development of a wide variety of fascinating one-pot asymmetric domino reactions, thereby allowing many complex products to be easily generated from simple materials in one step. The book also strictly follows the definition of domino reactions by Tietze as single-, two-, as well as multicomponent transformations. Asymmetric Metal Catalysis in Enantioselective Domino Reactions is divided into twelve chapters, dealing with enantioselective copper-, palladium-, rhodium-, scandium-, silver-, nickel-, gold-, magnesium-, cobalt-, zinc-, yttrium and ytterbium-, and other metal-catalyzed domino reactions. Most of the chapters are divided into two parts dealing successively with one- and two-component domino reactions, and three-component processes. Each part is subdivided according to the nature of domino reactions. Each chapter of the book includes selected applications of synthetic methodologies to prepare natural and biologically active products. -Presents the novel combination of asymmetric metal catalysis with the concept of fascinating domino reactions, which allows high molecular complexity with a remarkable level of enantioselectivity -Showcases an incredible tool synthesizing complex and diverse chiral structures in a single reaction step -Includes applications in total synthesis of natural products and biologically active compounds -Written by a renowned international specialist in the field -Stimulates the design of novel asymmetric domino reactions and their use in the synthesis of natural products, pharmaceuticals, agrochemicals, and materials Asymmetric Metal Catalysis in Enantioselective Domino Reactions will be of high interest to synthetic, organic, medicinal, and catalytic chemists in academia and R&D departments.

Asymmetric autocatalysis is a reaction in which chiral compound acts as a chiral catalyst for its own production. The process is a catalytic automultiplication of the chiral compound leading to an end product with a high enantiomeric excess. It has advantages over non-autocatalytic reactions because the amount of catalyst increases and no loss or deterioration of the catalyst is observed. Additionally, because the catalyst and product have the same structure, the separation of product from the catalyst is not necessary. Asymmetric Autocatalysis provides a comprehensive introduction to the topic of autocatalysis and an in-depth review of the current state of the research. Edited by a team including Professor Kenso Soai, who first described these types of reaction, and written by experts from around the world this book is a great resource for anyone with an interest in organic synthesis, catalysis and chirality.

Non-conventional synthetic methods may provide new and green methods for the preparation of bioactive heterocycles. These methods, such as microwave and ultrasound assisted synthesis, biocatalysis, photochemistry and electrosynthesis use less energy and may produce less waste to get the desired products when compared to traditional methods. This book explores the use of these methods when synthesizing various biologically relevant heterocyclic scaffolds. THE SERIES: GREEN BIOACTIVE HETEROCYCLES Heterocycles are a widely utilized group of molecules as they often contain bioactivity that is useful in drug development, agriculture, and other applications. However, their synthesis remains challenging with diffi cult to control functional groups. With a greater focus on sustainable synthesis practices, there is a need to develop greener synthetic methods for the synthesis of structurally diverse bioactive heterocyclic scaffolds. This series aims to do so, by collecting developments into common themes.

Historically the field of heterogeneous catalysis has focused on the design and optimisation of the catalytic materials. However, as these optimisations start to reach diminishing returns, attention has turned to non-conventional means for improving reaction conditions such as the use of ultrasound, plasma, electromagnetic heating and microwave heating. Microwave-assisted catalysis has been demonstrated to be useful in a wide range of applications including ammonia synthesis, desulfurization and production of chemicals from biomass. Advances in Microwave-assisted Heterogeneous Catalysis begins with the basics of microwave heating and the role of microwaves in heterogeneous catalysis. It goes on to cover the mechanisms of microwave specific reaction rate enhancement, microwave-assisted synthesis of porous, nonporous and supported metal catalysts, microwave augmented reactor technology and microwave-induced catalysis. The application of microwave-assisted heterogeneous catalysis in various fields of energy conversion, environmental remediation, and bulk and specialty chemicals synthesis are also discussed, making this a great reference for anyone involved in catalysis research.

Catalysis remains a key technology in a huge number of industrial processes in the 21st century. The catalytic properties of precious metals such as platinum and palladium are well understood. However, these metals are expensive and their supply is limited. Earth-abundant elements such as iron and nickel are, as the name suggests, in plentiful supply and much cheaper to use, but research on their use in catalysis has, historically, lagged behind. As researchers and companies increasingly look for ways to reduce costs and improve the sustainability of their processes there has been a renewed interest in these earth-abundant elements. This book presents a detailed overview of current research on the catalytic uses of the most Earth-abundant elements. Highlighting the top ten most Earth-abundant elements and their various roles in modern synthetic chemistry: s-block metals (Na, K, Mg, Ca), first-row transition metals (Ti, Mn, Fe), and p-block elements (Al, Si, P). The significant stoichiometric use of these elements, and their use as acid, base, dual, and/or redox catalysts will be discussed. It will be of use to industrial and academic researchers as well as graduate students with an interest in catalysis and sustainability.
