A unique guide to variable temperature CD spectroscopy and its application in organic chemistry
This timely, original, thought-provoking work looks at organic stereochemistry from the perspective of circular dichroism (CD), using variable temperature CD spectroscopy to determine the conformation or absolute configuration of chiral molecules. With an emphasis on the analysis of optically active ketones and the carbonyl chromophore, the authors demonstrate the advantages of this highly sensitive spectroscopic tool for obtaining stereochemical information in diverse areas of organic chemistry, biochemistry, and medicinal/pharmaceutical chemistry. They combine detailed examples of stereochemical analysis with clear, thorough presentations, correlating chiroptical data with molecular mechanics calculations as well as data from NMR spectroscopy and other spectroscopic techniques. In addition, they provide a systematic survey of the professional literature, featuring an extraordinary collection of original CD spectra run at varying temperatures. Coverage includes:
* Chiroptical measurements: CD and ORD (Optical Rotatory Dispersion)
* Conformational analysis of compounds ranging from simple cyclic ketones to polycyclics
* Conjugated and homoconjugated systems
* Stereochemistry of the carbon-carbon double bond
* Stereochemistry from exciton coupling of two or more chromophores
* An interesting historical account of the development of stereochemical concepts

|Stereochemistry of Radical Reactions: Concepts, Guidelines, and Synthetic Applications

Author: Dennis P. Curran
As little as a decade ago, radicals were regarded as interesting reactive intermediates with little synthetic use. However, recent results show that radicals have an enormous potential for applications in stereoselective reactions - it's all a matter of knowing what method to use and how to apply it.
Three world experts in the field have combined their expertise and present the concepts to understand and even to predict the course of stereoselective radical reactions. In addition, guidelines are established which will enable the readers to plan and carry out their own stereoselective syntheses with radicals. A comprehensive list of references provides an easy access to the primary literature.
The Stereochemistry of Radical Reactions is a highly topical introduction to this burgeoning field of research. Both advanced students and researchers active in the field will welcome this book as a source of concepts and ideas.

Stereochemistry covers the fundamental principles in all aspects of stereochemistry. This concise resource is generously enriched with numerous worked examples. Concentrating on organic chemistry, early chapters in this resourceful publication deal mainly with definitions of terms such as chirality, enantiomers, diastereoisomers and racemisation, complete with suitable examples to illustrate key concepts. Use of a polarimeter and associated definitions are described, together with two different conventions D, L and R, S for specification of configuration. The distinction between conformation and configuration is developed to include assignment onf configurations to di-substituted cyclohexanes and to the decalins.

Molecular stereochemistry is a fundamental aspect of all areas of chemistry. It is especially important in inorganic chemistry where the coordination numbers are variable and occasionally quite high. The present book evolved naturally from a series of articles written by Professor Kepert for Progre88 in Inorganic Ohemi8try, elucida ting aspects of the stereochemistry of inorganic compounds of co ordination numbers 4-12. In the present volume, Professor Kepert has added new sections and synthesized these individual chapters into a unified treatment, updating his references when necessary to the most recent contributions in the literature, and inter weaving the various themes as deemed appropriate. The result is a major contribution, describing the stereochemistry of coordi nation compounds having both unidentate and multidentate ligands. The viability of the repulsion approach to stereochemistry is tested to the limit in this treatise and shown to be an extremely good way of rationalizing a diverse body of data.

This book is written to introduce a new approach to stereochemical problems and to combinatorial enumerations in chemistry. This approach is based on group the ory, but different from conventional ways adopted by most textbooks on chemical group theory. The difference sterns from their starting points: conjugate subgroups and conjugacy classes. The conventional textbooks deal with linear representations and character ta bles of point groups. This fact implies that they lay stress on conjugacy classesj in fact, such group characters are determined for the respective conjugacy classes. This approach is versatile, since conjugacy classes can be easily obtained by ex amining every element of a group. It is unnecessary to know the group-subgroup relationship of the group, which is not always easy to obtain. The same situa tion is true for chemical enumerations, though these are founded on permutation groups. Thus, the P6lya-Redfield theorem (1935 and 1927) uses a cycle index that is composed of terms associated with conjugacy classes.
