Book Description
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.

Book Description
Advances in Asymmetric Autocatalysis and Related Topics provides various viewpoints on the important developments in asymmetric autocatalysis that have occurred in the past few years, also including brand new information in the field. Asymmetric autocatalysis is a chemical reaction which leads from achiral starting materials to chiral products, and in which the product accelerates its own formation reaction (conventional catalysis) and promotes the prevalence of its own chiral configuration (asymmetric induction). The combination of these two effects in the same reaction was unprecedented before 1995 when it was first described by Kenso SOAI at the Tokyo University of Science. Since then, several new combinations of this effect have been found, most intriguingly the possibility of absolute asymmetric synthesis, which is the spontaneous formation of the excess of one of the enantiomers of the product, a dream of organic chemists for more than a century. The book contains expert-contributed chapters that describe the most exciting recent developments in the field of the Soai reaction and in related topics, ranging from mechanistic studies and theoretical research, to very practical problems in chiral syntheses and products. - Features contributions from global experts, including several chapters from Kenso Soai and expert colleagues - Focuses on recent developments in the field of asymmetric autocatalysis and newly reported findings - Explores the Soai reaction, new developments, and the light it sheds on homochirality in certain biomolecules

Book Description
A compilation of recent advances and applications in asymmetric catalysis The field of asymmetric catalysis has grown rapidly and plays a key role in drug discovery and pharmaceuticals. New Frontiers in Asymmetric Catalysis gives readers a fundamental understanding of the concepts and applications of asymmetric catalysis reactions and discusses the latest developments and findings. With contributions from preeminent scientists in their respective fields, it covers: * "Rational" ligand design, which is critically dependent on the reaction type (reduction, oxidation, and C-C bond formation) * Recent findings on activation of C-H bonds, C-C bonds, and small molecules (C=O, HCN, RN=C, and CO2) and the latest developments on C-C bond reorganization, such as metathesis * Advances in "chirally economical" non-linear phenomena, racemic catalysis, and autocatalysis * Some of the recent discoveries that have led to a renaissance in the field of organocatalysis, including the development of chiral Brönstead acids and Lewis acidic metals bearing the conjugate base of the Brönstead acids as the ligands and the chiral bi-functional acid/base catalysts The book ends with a thought-provoking perspective on the future of asymmetric catalysis that addresses both the challenges and the unlimited potential in this burgeoning field. This is an authoritative, up-to-date reference for organic chemists in academia, government, and industries, including pharmaceuticals, biotech, fine chemicals, polymers, and agriculture. It is also an excellent textbook for graduate students studying advanced organic chemistry or chemical synthesis.

Book Description
A major strength of American Chemical Society (ACS) is the large number of volunteers who help to grow and sustain the organization, from local sections to technical divisions, from regional to national meetings, from task forces to national committees, and from conducting research to writing and reviewing manuscripts for journals. Some of them spend literally thousands of hours on behalf of ACS and the global chemistry enterprise, helping students or fellow scientists, organizing meetings and symposia, and reaching out to the local communities. One of the people who excelled in these efforts was the late Prof. Ernest L. Eliel. For many years he taught at the University of Notre Dame and the University of North Carolina and was an acknowledged leader in organic stereochemistry and conformational analysis. He was also a leader at ACS, serving as ACS President in 1992 and Chair of ACS Board of Directors in 1987-89. Unfortunately Prof. Eliel died in 2008, but the ACS held a symposium in 2016 honoring his work. This book features two volumes highlighting stereochemistry and global connectivity, which represent two of the key legacies of Prof. Eliel. Because stereochemistry is a fundamental chemistry concept, ongoing research is carried out in different subfields of chemistry (such as organic, medicinal, carbohydrates, polymers), using various analytical techniques (such as NMR, X-ray crystallography, and circular dichroism). The two volumes of this book contain many research papers that represent cutting-edge research in all the above areas. Because chemistry is now a world-wide enterprise, global connectivity is important to chemistry practitioners, and the chapters on international activities should be of great interest as well.

Book Description
This book addresses the timely subject of systems applications in astrobiology. It demonstrates how astrobiology – a multidisciplinary, interdisciplinary, and transdisciplinary field of science – can benefit from adopting the systems approach. Astrobiology draws upon its founding sciences, such as astronomy, physics, chemistry, biochemistry, geology, and planetary sciences. However, astrobiologists can encounter difficulties working across these fields. The systems approach, we believe, is the best contemporary approach to consider astrobiology holistically. The approach is currently used in other fields, such as engineering, which uses systems analysis routinely. Such an approach needs to be learned, both in principle and through examples, from the field. This book features chapters from experts across the field of astrobiology who have applied the systems approach. It will be a valuable guide for astrobiology students at the advanced undergraduate and graduate levels, in addition to researchers in the field, both in academia and the space industry. Key Features: Offers a unique and novel approach to studying and understanding astrobiology Encourages astrobiologists to apply a holistic systems approach to their work, rather than being bogged down in details Imparts practical knowledge to readers which can be adopted in different research and job opportunities in the field of astrobiology Vera M. Kolb obtained degrees in chemical engineering and organic chemistry from Belgrade University, Serbia, and earned her PhD in organic chemistry from Southern Illinois University, Carbondale, Illinois, United States. Following a 30-year career, she is Professor Emerita of Chemistry at the University of Wisconsin-Parkside, Kenosha, Wisconsin. During her first sabbatical leave with the NASA Specialized Center of Research and Training (NSCORT) in Astrobiology, she conducted research with Dr. Leslie Orgel at the Salk Institute and Prof. Stanley Miller at UC San Diego. Her second sabbatical was with Prof. Joseph Lambert at Northwestern University, where she studied sugar silicates and their potential astrobiological relevance. She is credited for authoring over 160 publications, in the fields of organic and medicinal chemistry, green chemistry, and astrobiology, including several books. Recently, she authored Green Organic Chemistry and Its Interdisciplinary Applications (CRC 2016). In the astrobiology field, she edited Astrobiology: An Evolutionary Approach (CRC 2015) and Handbook of Astrobiology (CRC 2019). She co-authored (with Benton C. Clark) Astrobiology for a General Reader: A Questions and Answers Approach (CSP 2020) and Systems Approach to Astrobiology (CRC 2023).
