Book Description
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 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

Book Description
Studies in Natural Products Chemistry: Bioactive Natural Products (Part XIII) is the latest in a series that covers the synthesis or testing and recording of the medicinal properties of natural products, providing cutting-edge accounts of the fascinating developments in the isolation, structure elucidation, synthesis, biosynthesis, and pharmacology of a diverse array of bioactive natural products. Natural products in the plant and animal kingdom offer a huge diversity of chemical structures that are the result of biosynthetic processes that have been modulated over the millennia through genetic effects. With the rapid developments in spectroscopic techniques and accompanying advances in high-throughput screening techniques, it has become possible to quickly isolate and determine the structures and biological activity of natural products, thus opening up exciting opportunities in the field of new drug development to the pharmaceutical industry. - Focuses on the chemistry of bioactive natural products - Contains contributions by leading authorities in the field - Presents sources of new pharmacophores

Book Description
Advances in Sulfur Chemistry, Volume 1 provides information pertinent to the four key aspects of sulfur chemistry. This book illustrates the great utility of sulfur in organic synthesis as applied to the synthesis of cyclic compounds, most of which serve as intermediates in the total synthesis of natural products. Organized into five chapters, this volume begins with an overview of desulfurization using Raney nickel. This text then highlights the extensive research done on compounds containing both phosphorus and sulfur attached to the same carbon atom, revealing synergism involving these adjacent second row heteroatoms. Other chapters consider the significant class of thiaheterocycles and include a discussion of the chemistry of disulfur. The final chapter deals with the chemistry of metal complexes of thiols, with focus on the chemistry, structure, and chemical modeling of the nitrogenase enzyme system, whereby dinitrogen is ultimately reduced to ammonia. This book is a valuable resource for graduate students, postdoctoral fellows, industrial chemists, and those teaching specialized topics to graduate students.

Book Description
Progress in Heterocyclic Chemistry (PHC) is an annual review series commissioned by the International Society of Heterocyclic Chemistry (ISHC). The volumes in the series contain both highlights of the previous year's literature on heterocyclic chemistry and articles on new developing topics of interest to heterocyclic chemists. The highlight chapters in Volume 10 are all written by leading researchers in their field and these chapters constitute a systematic survey of the important original material reported in the literature on heterocyclic chemistry in 1997. Additional articles in this volume also review "The Synthesis of Chlorins, Bacteriochlorins, Isobacteriochlorins" and "Higher Reduced Porphyrins and Heterocyclic ortho-Quinodimethanes". As with previous volumes in the series, Volume 10 will enable academic and industrial chemistry and advanced students to keep abreast of developments in heterocyclic chemistry in an effortless way.

Book Description
The present volume considers the most recent developments in the chemistry of cyclic inorganic and organoelement compounds. Nineteen of the 22 chapters are based on invited and other lectures presented at the 6th International Symposium on Inorganic Ring Systems held in Berlin on August 18-22, 1991. Main group compounds dominate the content from boron via carbon, silicon, germanium, tin, nitrogen, phosphorus and arsenic, to sulfur and selenium. The book is organized by element, moving from left to right in the main groups of the Periodic Table, followed by one chapter each on bonding and nomenclature of ring molecules. The list of contributors comprises distinguished scientists from 8 countries.

Book Description
Polar organometallic compounds are indispensable for the synthetic chemist. As this book shows, these almost ideal reagents are easy to prepare with high specificity under mild conditions and yet react quite readily with a great variety of substrates. Many compounds can be metallated directly at positions which would otherwise be difficult to substitute. Functional groups and heteroatoms already present in a molecule direct metallation to sites in their vicinity. The rules which govern polar organometallic chemistry often are not dominated by the usual n-delocalization and inductive effects; dipolar interactions, chelation, polarization, etc. often can be much more important. This affords novel synthetic opportunities. A good example is the development of a basically new type of aromatic substitution chemistry not based on positively charged intermediates. Seebach's injunction, "Thinking of polar organometallic compounds as carbanions is an impoverishment rather than a simplification" (International Symposium, Chemistry of Carbanions, Durham 1984), stresses the need to consider the metal not only as an integral, but perhaps also as the key component of these reagents. Rather than wandering off as solvated cations and acting as uninvolved spectators, the metals, rather than the anion moieties, can initiate and govern the subsequent reactions. To the founders of this field, e. g. Grignard, Ziegler, Gilman, Wittig, and their followers, the metal was critical. The title of Schlosser's book, "Polare Organometalle", certainly was apt.

Book Description
A wonderfully successful NATO Advanced Study Institute on "Sulfur-Centered Reactive Intermediates in Chemistry and Biology" was held 18-30 June, 1989, at the Hotel Villa del Mare in Maratea, Italy. Despite the beautiful setting with mountains behind us and over looking the clear blue Mediterranean Sea under a cloudless sky (and with a private beach available), the lectures were extremely well attended. While some credit can go to the seriousness of the students, more must go to the calibre of speakers and the high quality of C. Chatgilialoglu, and Co-Director, Professor K. -D. their presentations. The Director, Dr. Asmus, are to be congratulated for putting together such an outstanding scientific program. Dr. Chatgilialoglu is also to be commended for arranging an equally stimulating social pro gram which included bus, train and boat trips to many local sites of interest. It was particularly fitting that a meeting on the chemistry and biochemistry of sulfur should be held in Italy since Italian chemists have made major contributions to our under standing of the organic chemistry of sulfur, including the chemistry of its reactive inter mediates. The early Italian interest in sulfur chemistry arose from the fact that Italy, or more specifically, Sicily, was a major world producer of sulfur prior to the development and exploitation of the Frasch process in Texas and Louisiana.
