N-Heterocyclic Carbenes in Transition Metal Catalysis

It was only in the early 1990s that carbenes with the carbene carbon being incorporated in a nitrogen containing heterocycle (N-heterocyclic carbenes or NHCs) were found to be stable enough to be isolated. Since the first report on the application of NHCs as ligands in transition metal catalysis in 1995, NHC have found numerous applications and have been established as a versatile and indispensable class of ligands. For many reactions like metathesis or cross-coupling reactions NHCs have often become the ligands of choice, allowing otherwise difficult transformations. In this book leading experts have surveyed major areas of application of NHC metal complexes in catalysis. The authors have placed a special focus on nickel- and palladium-catalyzed reactions, on applications in metathesis reactions, on oxidation reactions and on the use of chiral NHC-based catalysts. This compilation is rounded out by an introductory chapter and a chapter dealing with synthetic routes to NHC metal complexes.

Microwave-Assisted Synthesis of Heterocycles

This book is Volume I of a new series by Springer entitled Topics in Heterocyclic Chemistry. At present, there are six such monographs in this series, the overall scope of which is to cover "current trends in heterocyclic chemistry". Given the importance of heterocylic natural products and heterocyclic scaffolds in the realm of medicinal chemistry and drug discovery, an up-todate series on this subject is well warranted, and a survey of the recent impact of microwave-assisted synthesis on this venerable field is both timely and needed

Micromanufacturing and Nanotechnology

Micromanufacturing and Nanotechnology is an emerging technological infrastructure and process that involves manufacturing of products and systems at the micro and nano scale levels. Development of micro and nano scale products and systems are underway due to the reason that they are faster, accurate and less expensive. Moreover, the basic functional units of such systems possesses remarkable mechanical, electronic and chemical properties compared to the macro-scale counterparts. Since this infrastructure has already become the prefered choice for the design and development of next generation products and systems it is now necessary to disseminate the conceptual and practical phenomenological know-how in a broader context. This book incorporates a selection of research and development papers. Its scope is the history and background, underlynig design methodology, application domains and recent developments.

Heterocycles from Carbohydrate Precursors

This book is a volume in the series Topics in Heterocyclic Chemistry.Itc- ers the key methods used for designing synthetic approaches to heterocycles from carbohydrates and the value and scope of these methods. Carbohydrates are widely distributed in nature and constitute the largest part of renewable biomasses. Moreover, many carbohydrates and their derivatives are comm- cially available at relatively cheap prices. Consequently their utilization is highly encouraged and economically they are of great signifcance. Moreover, carbohydrates are highly functionalized compounds that can be readily deritized and/or cyclized to provide heterocyclic compounds. This book provides a modern account and an up-to-date description of the advancement in the synthesis of diverse heterocycles from carbohydrates. Carbohydrates can be considered as a source of chiral centers in addition to the variable modifcation thereof.

Azaheterocycles Based on -, ß-Unsaturated Carbonyls

Devoted to heterocyclizations of aliphatic and aromatic, -unsaturated carbonyls with various binucleophiles leading to three-, five-, six and seven-membered partially hydrogenated nitrogen-containing heterocycles. During the last decade interest in these classes of organic c- pounds has been experiencing a scientific renaissance owing to their significant role in biological processes in living cells and diverse effects on physiological activities. In addition, such compounds are also more prevalent from the vi- point of ''classical'' problems of organic chemistry, among them reactivity, chemo- and regioselectivity, tautomerism, conformational analysis and features of their electronic structure. The character of these problems in the case of partially hydrogenated heterocycles differs sufficiently from that for hetero- omatized and perhydrogenated heterocyclic compounds and investigations in this field very often lead to interesting and unusual results. Extensively characterized cyclocondensations of, -unsaturated carbonyls, their synthetic equivalents and their precursors are the most widespread, facile and generally valid pathway to dihydroazaheterocycles.
