A thorough understanding of stereochemistry is essential for the comprehension of almost all aspects of modern organic chemistry. It is also of great significance in many biochemical and medicinal disciplines, since the stereoisomers of a compound can have dramatically different biological properties. This text explains how the different properties of stereoisomers of a compound arise, and what processes can be used to prepare and analyze stereoisomerically pure compounds. It also presents prominent coverage of the stereochemistry of inorganic and organometallic compounds, which is likely to increase in importance, as these compounds are used as symmetric catalysts in asymmetric synthesis. Modern stereochemical terminology is used throughout, although reference is also made to older terms which are still widely used. A set of problems at the end of each chapter aims to further the reader's understanding of how the content can be applied. The book is designed mainly as a textbook for undergraduate students and as a reference source for more advanced levels, but is also intended for academic and professional organic chemists.

“Much of life can be understood in rational terms if expressed in the language of chemistry. It is an international language, a language without dialects, a language for all time, a language that explains where we came from, what we are, and where the physical world will allow us to go. Chemical Language has great esthetic beauty and links the physical sciences to the b- logical sciences. ” from The Two Cultures: Chemistry and Biology by Arthur Kornberg (Nobel Prize in Physiology and Medicine, 1959) Over the past two centuries, chemistry has evolved from a relatively pure disciplinary pursuit to a position of central importance in the physical and life sciences. More generally, it has p- vided the language and methodology that has unified, integrated and, indeed, molecularized the sciences, shaping our understanding of the molecular world and in so doing the direction, development and destiny of scientific research. The “language of chemistry” referred to by my former Stanford colleague is made up of atoms and bonds and their interactions. It is a s- tem of knowledge that allows us to understand structure and events at a molecular level and increasingly to use that understanding to create new knowledge and beneficial change. The words on this page, for example, are detected by the eye in a series of events, now generally understood at the molecular level.

Stereoisomers are compounds with the same chemical formula and connectivity but with different arrangements of their atoms in 3-dimensional space. Stereochemistry encompasses the study of stereoisomers and their properties. Despite having an identical chemical formula, stereoisomers can have drastically different biological, medicinal, and chemical properties. Basic Organic Stereochemistry explains in clear, concise terms the concepts and properties of stereoisomers. Ideal both as a text for advanced undergraduate or graduate students and as a handy guide for researchers in industry, this superb text covers: Polarimetry and optical rotation Internal coordinates, configuration, and conformation Nature of stereoisomers Barriers between stereoisomers and residual stereoisomers Symmetry operators and symmetry point groups Properties of stereoisomers and stereoisomer discrimination Separation of stereoisomers, resolution, and racemization Suitable for students in organic and biological chemistry, Basic Organic Stereochemistry is unparalleled as a convenient text.

Winner of the PROSE Award for Chemistry & Physics 2010 Acknowledging the very best in professional and scholarly publishing, the annual PROSE Awards recognise publishers' and authors' commitment to pioneering works of research and for contributing to the conception, production, and design of landmark works in their fields. Judged by peer publishers, librarians, and medical professionals, Wiley are pleased to congratulate Professor Ian Fleming, winner of the PROSE Award in Chemistry and Physics for Molecular Orbitals and Organic Chemical Reactions. Molecular orbital theory is used by chemists to describe the arrangement of electrons in chemical structures. It is also a theory capable of giving some insight into the forces involved in the making and breaking of chemical bonds—the chemical reactions that are often the focus of an organic chemist's interest. Organic chemists with a serious interest in understanding and explaining their work usually express their ideas in molecular orbital terms, so much so that it is now an essential component of every organic chemist's skills to have some acquaintance with molecular orbital theory. Molecular Orbitals and Organic Chemical Reactions is both a simplified account of molecular orbital theory and a review of its applications in organic chemistry; it provides a basic introduction to the subject and a wealth of illustrative examples. In this book molecular orbital theory is presented in a much simplified, and entirely non-mathematical language, accessible to every organic chemist, whether student or research worker, whether mathematically competent or not. Topics covered include: Molecular Orbital Theory Molecular Orbitals and the Structures of Organic Molecules Chemical Reactions — How Far and How Fast Ionic Reactions — Reactivity Ionic Reactions — Stereochemistry Pericyclic Reactions Radical Reactions Photochemical Reactions This expanded Reference Edition of Molecular Orbitals and Organic Chemical Reactions takes the content and the same non-mathematical approach of the Student Edition, and adds extensive extra subject coverage, detail and over 1500 references. The additional material adds a deeper understanding of the models used, and includes a broader range of applications and case studies. Providing a complete in-depth reference for a more advanced audience, this edition will find a place on the bookshelves of researchers and advanced students of organic, physical organic and computational chemistry. The student edition of Molecular Orbitals and Organic Chemical Reactions presents molecular orbital theory in a simplified form, and offers an invaluable first textbook on this important subject for students of organic, physical organic and computational chemistry. Further information can be viewed here. "These books are the result of years of work, which began as an attempt to write a second edition of my 1976 book Frontier Orbitals and Organic Chemical Reactions. I wanted to give a rather more thorough introduction to molecular orbitals, while maintaining my focus on the organic chemist who did not want a mathematical account, but still wanted to understand organic chemistry at a physical level. I'm delighted to win this prize, and hope a new generation of chemists will benefit from these books." —Professor Ian Fleming

Das explosionsartige Anwachsen des chemischen Wissens hat in den letzten Jahrzehnten im Bereich der organischen Chemie zu einer schier unübersehbaren Anzahl neuer und neuartiger Verbindungen und Verbindungsklassen geführt, deren rationelle Benennung immer größere Schwierigkeiten bereitete. Ursprünglich war ja die Namensgebung eines neuen Stoffes weitgehend, wenn nicht völlig in das Belieben des Entdeckers gestellt, der den Namen häufig von einer direkten sinnlichen Wahrnehmung ableitete oder sich gar ganz von der Intuition leiten ließ. Da die mehr oder weniger willkürlich gebildeten "Trivialnamen" meist gar nichts über die Strukturen der Verbindungen aussagten, konnten sie auch in keinen sinnvollen Zusammenhang zueinander ge bracht werden. Mit dem zunehmenden Verständnis der strukturellen Beziehungen der Organischen Chemie wuchs aber die Tendenz, eine allgemeinverbindliche und systema tische Nomenklatur zu entwickeln, die es erlauben sollte, wesentliche konstitutionelle Aussagen über ein Molekül be reits aus dessen Namen abzuleiten. Andererseits wollte man einen großen Teil der althergebrachten Trivial- und Semi trivialnamen nicht so ohne weiteres aufgeben. Dennoch ist es den damit befaßten Instanzen der "International Union of Pure and Applied Chemistry", der IUPAC, gelungen, ein einheitliches und ausbaufähiges Nomen klatursystem zu entwickeln, das mittlerweile allgemein und international anerkannt ist. Die Originalfassung der IUPAC Nomenklaturregeln der Organischen Chemie ist ein unver zichtbares Hilfsmittel für den Spezialisten. Als Einführung in die Materie ist jedoch eine knappere und präzisere "Ge brauchsanweisung" eher am Platze, die an Hand zahlreicher, sorgfältig ausgewählter bzw. konstruierter Beispiele die Geltungsbereiche der einzelnen Regeln möglichst voll ständig überstreicht.
