Book Description :

Copper in N-Heterocyclic Chemistry provides an overview of copper-catalyzed synthesis and functionalization of N-heterocyclic compounds, covering all recent developments in a way that is ideal for researchers and students working in the area of synthetic organic chemistry and medicinal chemistry. The book explores N-heterocyclic compounds as unique structural units in the development of natural products and pharmaceuticals, along with the remarkable progress made in the area of high atom economic strategies, and more recently, copper-catalyzed C-H activation and its applications in organic synthesis. Readers will find troubleshooting protocols, as well as the advantages and limitations of each method discussed. As copper catalysts show versatile chemical reactivity in many aspects, including their oxidation states 0–3 are accessible and their ability to facilitate bond formations due to their ability to serve as Lewis acids, oxidizing agents and catalysts, this book is an ideal resource on the topics explored. Discusses novel synthetic methods developed over the past decade for copper-catalyzed synthesis of N-heterocyclic compounds Covers the most recent methodologies adapted in synthetic chemistry for applications in natural products and pharmaceuticals Includes troubleshooting protocols, as well as the advantages and limitations of each method discussed in detail

Book Description :

Sulfonyl ynamides are highly versatile and synthetically useful reagents. This thesis details the modular synthesis and use of sulfonyl ynamides in order to access N-heterocyclic scaffolds, such as quinolines and pyrazoles. The synthesis of a wide array of sulfonyl ynamides can be realized via copper-catalyzed amidative cross-couplings or by elimination of dichloroenamide precursors. Additionally the use of Sonogashira chemistry to further diversify terminal ynamides and the synthesis of solid-supported ynamides was investigated. Electrophilically-activated amides can be reacted with sulfonyl ynamides in order to access highly functionalized 4-aminoquinolines. The straightforward amide activation procedure with triflic anhydride and 2-chloropyridine was found to tolerate a wide range of substrates, which allowed for the development of a library of 4-aminoquinolines with ease. Moreover, 4-aminopyrazoles can be prepared by reacting terminal sulfonyl ynamides with sydnones under copper catalysis. However, as the copper catalysts were also found to promote the degradation of the ynamides, a copper-free strain-promoted alternative was developed. An in situ prepared 3-azacyclohexyne was found to tolerate a wide array of C-4 substituted sydnones, producing a mixture of both the 3,4- and 4,3-fused pyrazoles in good yields. Additional investigations into heterocyclic methodology led to the development of highly sophisticated, non-symmetrical and axially-chiral dibenzo-1,3-diazepines, -oxazepines and -thiazepines from simple, commercially available anilines. The anilines were coupled to their corresponding reaction partners via a chloromethyl intermediate and the 7-membered ring was subsequently formed using direct arylation.

Book Description :

Heterocyclic chemistry is the largest of the classical divisions of organic chemistry. Heterocyclic compounds are widely distributed in Nature, playing a vital role in the metabolism of living cells. Their practical applications range from extensive clinical use to fields as diverse as agriculture, photography, biocide formulation and polymer science. The range of known compounds is enormous, encompassing the whole spectrum of physical, chemical and biological properties. This book provides a balanced, concise and informative account of heterocyclic chemistry that will be suitable for graduate or advanced undergraduate students and a convenient reference book for research workers, for both specialists int he field and those whose expertise lies in other areas but who nevertheless need information on heterocylic chemistry. The Handbook of Heterocyclic Chemistry is illustrated throughout with thousands of clearly drawn chemical structures. The highly systematic coverage given to the subject makes this the most authoritative one-volume account of modern heterocyclic chemistry available.

Book Description :

The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects – properties, synthesis, reactions, physiological and industrial significance – of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all authors are recognized authorities, the Chemistry of Heterocyclic Chemistry is considered worldwide as the indispensable resource for organic, bioorganic, and medicinal chemists.

Book Description :

Over the last fifteen years, N-heterocyclic carbenes (NHCs) have mostly been used as ancillary ligands for the preparation of transition metal-based catalysts. Compared to phosphorus-containing ligands, NHCs tend to bind more strongly to metal centres, avoiding the necessity for the use of excess ligand in catalytic reactions. The corresponding complexes are often less sensitive to air and moisture, and have proven remarkably resistant to oxidation. Recent developments in catalysis applications have been facilitated by the availability of carbenes stable enough to be bottled, particularly for their use as organocatalysts. This book shows how N-heterocyclic carbenes can be useful in various fields of chemistry and not merely laboratory curiosities or simple phosphine mimics. NHCs are best known for their contribution to ruthenium and palladium-catalysed reactions but the scope of this book is much broader. The synthesis of NHC ligands and their corresponding metal complexes are covered in depth. Moreover, the biological activity of NHC-containing complexes, as well as an overview of their theoretical aspects are included. Such metal species are further examined, not only in terms of their catalytic applications, but also of their stereoelectronic parameters and reactivity/stability. Finally, special attention is given to the hot topic of organocatalysis. The book will be of interest to postgraduates, academic researchers and those working in industry.
