Описание: Les hypotheses, n'en deplaise a mon contradicteur, sont l'ame des progres de la science. Louis Pasteur The concept of chirality, established 100 years ago, plays an im- portant role in almost all domains and dimensions of our recent scientific view of life. Chiral properties can be found in fundamen- tal nuclear particles, in molecules, and in the macroscopic world of living nature (plants and animals) and inanimate nature (crystals). In particular, chirality, or more precisely chiral excess, is evident in human beings. For example, the expected symmetry of the hands turns out to be functionally non-existent. Consequently chirality occurs in the technical sphere, where screws are the best-known examples, since most of them are made for right-handed people. Chirality is not confined to static objects but influences processes such as chemical reactions. The occurrence of chiral objects on different dimensional scales has been treated in the past in mutually independent frameworks. There were, however, two remarkable events from which the conclu- sion can be drawn that the appearance of chirality in various fields has a common cause. On the one hand, physicists found evidence that the well-known biomolecular homochirality can be traced back to the chirality of weak bosons. At the same time, on the other hand, the so-called thalidomide tragedy occurred when thalido- mide molecules of a certain chirality, taken by pregnant women, caused deformed children.

Описание: 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.
