Book Description
Chapter contribution from Ben Feringa, Nobel Laureate in Chemistry 2016.Atropisomerism and Axial Chirality provides a global survey of the chemistry of axially chiral compounds including biaryls, heterobiaryls, non-biaryl atropisomers, allenes and spyrocyclic derivatives. From the perspective of a synthetic organic chemist, this book provides a unique compilation of the available methodologies for their synthesis, with emphasis on the most efficient and modern strategies, a review of the huge amount of practical applications in the field of asymmetric catalysis, either as transition metal ligands or as organocatalysts, and an overview of their occurrence as bioactive compounds and natural products.The first of its kind, this book serves as a general introduction and a practical reference to advanced chemistry students and researchers, while also offering creative ideas for further developments in the field.

Book Description
Catalytic asymmetric synthesis has been one of the most active research areas in chemistry (Nobel Prize in 2001). The development of efficient chiral catalysts plays a crucial role in asymmetric catalysis. Although many chiral ligands/catalysts have been developed in the past decades, the most efficient catalysts are derived from a few core structures, called "privileged chiral catalysts". This ultimate "must have" and long awaited reference for every chemist working in the field of asymmetric catalysis starts with the core structure of the catalysts, explaining why a certain ligand or catalyst is so successful. It describes in detail the history, the basic structural characteristics, and the applications of these "privileged catalysts". This novel presentation provides readers with a much deeper insight into the topic and makes it a must-have for organic chemists, catalytic chemists, chemists working with/on organometallics, chemists in industry, and libraries. From the contents: * BINAP * Bisphosphacycles - From DuPhos and BPE to a Diverse Set of Broadly Applied Ligands * Josiphos Ligands: From Discovery to Technical Applications * Chiral Spiro Ligands * Chiral Bisoxazoline Ligands * PHOX Ligands * Chiral Salen Complexes * BINOL * TADDOLate Ligands * Cinchona Alkaloids * Proline Derivatives

Book Description
This work describes the essential aspects of enantioselective catalysis, with chapters organised by concept rather than by reaction type. Each concept is supported by examples to give the reader broad exposure to a wide range of catalysts, reactions and reaction mechanisms.

Book Description
This book collects all the latest advances in the leading research of the circularly polarized luminescence (CPL) of small organic molecules. Compared with that of lanthanide-based fluorophores, the research into the CPL of small organic molecules is still at the developmental stage for their relatively smaller dissymmetric factors, but has been a source of widespread attention recently. The book includes the state of the art of the discoveries in CPL organic molecules, such as helicenes, biaryls, cyclophanes, boron dipyrromethene dyes, and other chiral molecules, mostly in their isolated states, covering all possible chiral substances for future applications. This book also highlights the recent development of CPL instruments as well as time-resolved circular dichroism spectroscopy, to facilitate the further development and future design of CPL molecules.

Book Description
In spite of important advances in asymmetric synthesis, chiral compounds cannot all be obtained in a pure state by asymmetric synthesis. As a result, enantiomer separation remains an important technique for obtaining optically active materials. Although asymmetric synthesis is a once-only procedure, an enantiomer separation process can be repeated until the optically pure sample is obtained. This book discusses several new enantiomer separation methods using modern techniques developed by experts in the field. These methods consist mainly of the following three types: 1) Enantiomer separation by inclusion complexation with a chiral host compound 2) Enantiomer separation using biological methods 3) Enantiomer separation by HPLC chromatography using a column containing a chiral stationary phase. Separation of a racemic compound has been called “optical resolution” or simply “resolution”. Nowadays, the descriptions “enantiomer resolution” or “enantiomer separation” are also commonly used. Accordingly, “Enantiomer Separation” is used in the title of this book. The editor and all chapter contributors hope that this book is helpful for scientists and engineers working in this field.

Book Description
This book systematically reviews recent advances in the synthetic methods and applications of helicenes. The first part of this book introduces the nomenclature and structural features of helicenes. The second part reviews several classic and useful methods as well as recently-developed approaches for the preparation and functionalization of helicenes, including photocyclization and Diels-Alder reactions, which are two important breakthroughs in the syntheses of helicenes. In the last part, the applications of helicenes in asymmetric syntheses, molecular machines, molecular recognition, self-assembly and other fields are discussed. This book provides a useful reference source for researchers and graduate students working not only in the area of helicene chemistry, but also in other research areas including materials science, supramolecular chemistry, coordination chemistry, and physical organic chemistry. Chuan-Feng Chen is a Professor at the Institute of Chemistry, Chinese Academy of Sciences, China.

Book Description
Asymmetric C-H direct functionalization reactions are one of the most active and fascinating areas of research in organic chemistry due to their significance in the construction of molecular complexity without pre-activation, and the step economy and atom economy features in potential synthetic application. Distinguishing the reactivity among numerous C–H bonds in one single molecule represents one of the most challenging issues in organic synthesis and requires precise reaction design. As such, this field is now receiving increasing attention from researchers. This book provides the first comprehensive review of this field, summarizing the origin, mechanism, scope and applications of the asymmetric C-H bond functionalization reaction. It covers organocatalytic reactions and transition-metal-catalyzed reactions, as well as asymmetric C-H functionalization reactions not described in other books. Written by a leading expert in this field, the book is ideal for postgraduates and researchers working in organic synthesis, catalysis, and organometallic chemistry.
