Modified Cyclodextrins for Chiral Separation offers a review of the latest advances in developing modified cyclodextrins as chiral selectors for various chromatographic and electromigration techniques. Over the years, many descriptions of chiral separation have appeared in academic journals and books, but most of them have been devoted to either the development of analytical methods and protocols or the summary of different chiral selectors, including cyclodextrins for chiral separation applications. This is in marked contrast to this volume which focuses on the research endeavors concerning the development of cyclodextrin derivatives specifically as either chiral mobile phases for capillary electrophoresis, or chiral stationary phases for various chromatographic techniques including gas chromatography, or high-performance liquid chromatography and supercritical fluid chromatography. The ongoing thread in this book is the synthesis of structurally-defined cyclodextrin derivatives and their applications in enantiomer separation by means of different analytical techniques. Modified Cyclodextrins for Chiral Separation is intended for those who are interested in expanding their knowledge of cyclodextrin chemistry and chiral separation, and in what cyclodextrin modification can be made to suit the needs of chiral selectors for different analytical techniques. It primarily focuses on the state-of-the-art cyclodextrin chemistry which is the basis for all chiral selectors used in these chiral separation techniques.

Enantiomer Separation is written by several experts working in modern enantiomer separation chemistry who understand the needs of the many scientific and engineering chemists who need a cost-efficient supply of optically active materials of high quality. This book contains the following modern practical methods of enantiomer separation: Inclusion complexation of a racemic compound with a chiral host compound, which gives chiral host-chiral guest inclusion compounds, from which the chiral guest can be obtained. When this separation is combined with distillation technique, for example, enantiomer separation can be accomplished by fractional distillation in the presence of a chiral host compound. This is a modern and "green" procedure of enantiomer separation. These separation methods are described in several chapters of the book. Biological separation methods and "green" methods are covered in two chapters. Enantiomer separation by chromatography on a column containing chiral solid phase is one of the most up-to-date and well known "green" methods of enantiomer separation. Two experts in chromatography have contributed to provide two very important chapters on this method of separation. Practical methods of enantiomer separation are important both in the research laboratory and in industry, especially in the pharmaceutical, fine chemical and electronic industries. Chemists and engineers, as well as students who are working in the field of chiral compounds in universities, institute and industry, will find this book an invaluable resource.

The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
