Organic Synthesis: Theory and Applications - Böcker

Volume 5 in this series spans a variety of topics including terpene synthesis, amino acid synthesis, and combinatorial methods for generation of structural diversity. The first chapter has been contributed by Trond Hansen and Professor Yngve Strenstr�m of the Agricultural University of Norway, and surveys naturally occurring cyclobutanes. As well as providing a review of representative syntheses and synthetic strategies for the introduction of cyclobutane into target molecules, the number of rings contained in the natural product is also discussed in logical order.The following chapter, written by Professor Timothy Brocksom, his wife Ursula, and a number of co-workers from the Federal University of São Carlos, surveys the synthesis of higher terpenes by the use of Diels-Alder reaction. A useful review of the current literature in this field is provided, together with 79 references and footnotes.The third chapter, written by Michael G. Natchus and Xinrong Tian of Procter & Gamble Pharmaceuticals, covers recent advances in the synthesis of unnatural amino acids. Three of the major asymmetric methods are discussed and grouped according to the chemistry involved.The fourth and final chapter has been contributed by Professor Dennis Wright of the University of Florida, and other co-workers. A review of the combinatorial chemistry methods currently available for lead discovery in pharmaceutical research is provided in this chapter, as well as discussions on the methods based on natural products and an overview of the complexity building techniques.

This fourth volume in the series Organic Synthesis: Theory and Applications is composed of five chapters that span a wide range of disciplines. Alkaloid chemistry, total synthesis, synthetic methodology, carbohydrate technology, and spin-trapping agents are all covered by experts in these fields.The first chapter is one of the finest examples of deductive reasoning in the chemical literature, examining the rich history of the chemistry of morphine. Within the following chapters, synthetic challenges of the marine terpenoids are brought into focus, the chemistry and synthetic applications of cyclobutenediones are reviewed and the utility of glycosyl iodides in the preparation of glycosides are summarized. Finally a report on a new class of spin-traping agents, azulenyl nitrones is covered. In all, five diverse subdisciplines are brought together and reviewed in this volume.
