A Course in Organic Chemistry Advanced Section, Volume 27: Indole Alkaloids: An Introduction to the Enamine Chemistry of Natural Products describes the chemistry of selected alkaloids that contain indolic or closely related nuclei. Some five hundred of these compounds have been obtained from about three hundred plants mostly of the family Apocynaceae. This book is composed of 12 chapters that specifically cover the chemistry of the complex indoles. The introductory chapters deal with the origin, isolation, characterization, basic chemistry, and simple derivatives of indole alkaloids. The remaining chapters examine the biogenesis, basic chemistry, stereochemistry, and structure of selected complex alkaloids of various origins. These chapters include tetrahydro-?-carboline, strychnos, iboga, picralima, and eburnamine alkaloids, cinchonamine, quinamine, and ajmaline-sarpagine bases. This text is of great value to organic chemists and researchers.

Indole Alkaloids: Spirooxindole details the multistep synthesis of natural products using schematic diagrams, providing a quick-and-easy way to review and understand new and novel synthetic strategies to construct structural frameworks of natural products. As a volume in the Visual Guides to Natural Product Synthesis series, this book presents the schematic total syntheses of natural products containing a "spirooxindole core structure. It covers spirooxindole molecules through visual diagrams, highlighting key steps involved in total, formal and semi-syntheses. Sections cover Brevianamide A and B, Citrinadin A and B, Coerulescine and Horsfiline, Elacomine and Isoelacomine, Gelsemine, Paraherquamide A and B, Rynchophylline, Isorynchophylline, and more. Visual layouts provide quick-and- easy access to developed synthetic routes towards the targeted spirooxindoles. - Outlines synthetic strategies for natural products bearing a spirooxindole core structure - Includes schematic diagrams of multistep synthetic routes, highlighting key steps along the way - Describes all routes for the formal synthesis, semi-synthesis and total synthesis of spirooxindole alkaloids

Internationally renowned specialists present a comprehensive survey of the latest advances in this area. The biosynthetic and structural relationships of these compounds are summarized and newly discovered alkaloids described. Discusses versatile biomimetic procedures as well as the pharmacology and clinical applications of monoterpenoid indole alkaloids. Botanical names of all plants cited have been extensively referenced.

The alkaloids were of great importance to mankind for centuries, long before they were recognized as a chemical class. The influence they have had on literature is hinted at by some of the quotations I have used as chapter headings. Their in fluence on folklore and on medicine has been even greater. The scientific study of alkaloids may be said to have begun with the isolation of morphine by SERTURNER in 1804. Since that time they have remained of great interest to chemists, and now in any month there appear dozens of publications dealing with the isolation of new alkaloids or the determination of the structures of previously known ones. The area of alkaloid biochemistry, in comparison, has received little attention, and today is much less developed. There is a certain amount of personal arbitrariness in defining "biochemistry", as there is in defining "alkaloid", and this arbitrariness is doubtless compounded by the combination. Nevertheless, it seems to me that in any consideration of the bio chemistry of a group of compounds three aspects are always worthy of attention pathways of biosynthesis, function or activity, and pathways of degradation. For the alkaloids, treatment of these three aspects is necessarily lopsided. Much has been learned about routes of biosynthesis, but information on the other aspects is very scanty. It would be possible to enter into some speculation regarding the biosyn thesis of all the more than 1,000 known alkaloids.
