The chemistry of heterocycles is an important branch of organic chemistry. This is due to the fact that a large number of natural products, e. g. hormones, antibiotics, vitamins, etc. are composed of heterocyclic structures. Often, these compounds show beneficial properties and are therefore applied as pharmaceuticals to treat diseases or as insecticides, herbicides or fungicides in crop protection. This volume presents important pharmaceuticals. Each of the 20 chapters covers in a concise manner one class of heterocycles, clearly structuredas follows: * Structural formulas of most important examples (market products) * Short background of history or discovery * Typical syntheses of important examples * Mode of action * Characteristic biological activity * Structure-activity relationship * Additional chemistry information (e.g. further transformations, alternative syntheses, metabolic pathways, etc.) * References. A valuable one-stop reference source for researchers in academia and industry as well as for graduate students with career aspirations in the pharmaceutical chemistry.

Organic Chemistry, Volume 18: The Chemistry of Indoles discusses the chemistry of indole derivatives. This book explores the potent biological activity of several indole derivatives and explains the structure of indole alkaloids. Organized into 10 chapters, this monograph starts with an overview of the most important types of reactions of the indole ring on a mechanical basis. This text then proceeds to review the methods of synthesizing indoles and describes the oxidations and rearrangements of indole derivatives. Other chapters explore the special features of the synthesis and reactivity of hydroxyindoles, acylindoles, and aminoindoles. This book discusses as well the properties of carboxyl groups, which is substituted on the benzenoid ring of the indole nucleus that is typical of aromatic carboxylic acids. The final chapter deals with the certain classes of indoles that are found in nature. Chemists, researchers, and readers interested in the chemistry of indoles will find this book extremely useful.

Dehydrobenzene and Cycloalkynes deals with the problems associated with the production and reactions of dehydrobenzene and of the related fields of dehydroheterocycles and cycloalkynes. This book also describes the various synthetic applications of dehydrobenzene and provides a list of reactions in which dehydrobenzene occurs as an intermediary. The text explains the generation of dehydrobenzene by cleavage of cyclic systems, by photolytic methods, and by free radical reactions. Nucleophilic and electrophilic monodentate attacks on dehydrobenzene, as well as, bidentate additions to dehydrobenzene yielding cycloadducts. The book also notes that dehydrobenzene is not only a transition state but can be an intermediate of characteristic selectivity and lifetime. The reactions of dehydrobenzene in the gaseous phase affirm that the existence of dehydrobenzene is not restricted to the presence of a solvation shell. The researcher can then study the molecular structure of dehydrobenzene when its existence has been fully established. The text also extends the principle that the dehydroaromatic intermediates can be obtained by abstracting two adjacent hydrogen atoms from an aromatic substrate different from the 1- and 2- positions to arrive at a 1,3- and 1,4-dehydrobenzene. Researchers and scientists whose works are associated with organic chemistry, analytical chemistry, molecular physics or physical chemistry will find this book valuable.
