About the Book:’It is indeed the merit of Dr. Alan F. Casy to bring in these pages a clear and comprehensive view of medicinal stereochemistry, a discipline in which he has been active and successful for many years both as a teacher and a researcher. Written for graduate students and research workers in medicinal chemistry and pharmacology, this book will contribute significantly towards a better education of scientists by removing the fear of stereochemistry caused by ignorance, moderating the overconfidence of possible zealots, and outlining a broader context.’-from the foreword by Bernard Testa
