This classical textbook in the best sense of the word is now completely revised, updated and with more than 40 % new content. The approved ordering system according to the ring size of the heterocycles has been retained, while the important chapter on "Problems and their Solutions" has been almost completely renewed by introduction of up-to-date scientific exercises, resulting in a great tool for self-testing and exams. There was maintained a chapter on nomenclature and a helpful index of name reactions. With approximately 1,000 new literature citations, this book remains a brilliant gateway to modern heterocyclic science for master and graduate students, as well as PhDs and researchers entering the field. "If you want quick information about the basic (or acidic!) properties of a heterocycle, some interesting facts, or an assorted few ways of making it, this book provides a welcoming, accurate, and concise introduction." Angewandte Chemie IE "Eicher, Speicher and Hauptmann provide an up to date introduction to the field for the advanced undergraduate and graduate students. ... The book is carefully produced to a very high standard." European Journal of Medicinal Chemistry
