Book Description
This book investigates the use of palladium modified by bulky ligands as catalysts for new chemical transformations that rapidly assemble several classes of complex heterocyles. It documents the development of new chemical reactions involving carbon–carbon (C‒C) and carbon–halogen (C‒X) bond formation in the context of alkene difunctionalization and dearomatization reactions. Due to the ubiquity of heterocycles in bioactive natural products and life-improving pharmaceutical treatments, a long-term goal for synthetic organic chemists has been to develop novel and creative heterocycle syntheses that illicit a high degree of product diversity and are characterized by mild reaction conditions and limited waste production. A considerable fraction of leading pharmaceutical drugs contain at least one heterocycle within their chemical structure, and their prevalence in these technologies is strong evidence that the fundamental curiosities of organic chemistry lead to real-world solutions for the health and wellness of the global population.

Book Description
This book is a compilation of the recent applications of palladium catalysts in organic synthesis. The book demonstrates that it is a highly dynamic research field. This methodology has emerged as a powerful tool for the efficient and chemoselective synthesis of heterocyclic molecules. In the past few years, several strategies have been pointed out to pursue more efficient, sustainable, and environment friendly chemical processes. Among those strategies, catalysis and the design of new processes that avoid the use of toxic reagents have been the focus of intense research.

Book Description
Hypervalent Iodine Chemistry is the first comprehensive text covering all of the main aspects of the chemistry of organic and inorganic polyvalent iodine compounds, including applications in chemical research, medicine, and industry. Providing a comprehensive overview of the preparation, properties, and synthetic applications of this important class of reagents, the text is presented in the following way: The introductory chapter provides a historical background and describes the general classification of iodine compounds, nomenclature, hypervalent bonding, structural features, and the principles of reactivity of polyvalent iodine compounds. Chapter 2 gives a detailed description of the preparative methods and structural features of all known classes of organic and inorganic derivatives of polyvalent iodine. Chapter 3, the key chapter of the book, deals with the many applications of hypervalent iodine reagents in organic synthesis. Chapter 4 describes the most recent achievements in hypervalent iodine catalysis. Chapter 5 deals with recyclable polymer-supported and nonpolymeric hypervalent iodine reagents. Chapter 6 covers the "green" reactions of hypervalent iodine reagents under solvent-free conditions or in aqueous solutions. The final chapter provides an overview of the important practical applications of polyvalent iodine compounds in medicine and industry. This book is aimed at all chemists interested in iodine compounds, including academic and industrial researchers in inorganic, organic, physical, medicinal, and biological chemistry. It will be particularly useful to synthetic organic and inorganic chemists, including graduate and advanced undergraduate students. It comprehensively covers the green chemistry aspects of hypervalent iodine chemistry, making it especially useful for industrial chemists.

Book Description
The extraordinary potential of fluorine-containing molecules in medicinal chemistry and chemical biology has been recognized by researchers outside of the traditional fluorine chemistry field, and thus a new wave of fluorine chemistry is rapidly expanding its biomedical frontiers. With several of the best selling drugs in the world crucially containing fluorine atoms, the incorporation of fluorine to drug leads has become an essential practice in biomedical research, especially for drug design and discovery as well as development. Focusing on the unique and significant roles that fluorine plays in medicinal chemistry and chemical biology, this book reviews recent advances and future prospects in this rapidly developing field. Topics covered include: Discovery and development of fluorine containing drugs and drug candidates. New and efficient synthetic methods for medicinal chemistry and the optimisation of fluorine-containing drug candidates. Structural and chemical biology of fluorinated amino acids and peptides. Fluorine labels as probes in metabolic study, protein engineering and clinical diagnosis. Applications of 19F NMR spectroscopy in biomedical research. An appendix presents an invaluable index of all fluorine-containing drugs that have been approved by the US Food and Drug Administration, including information on structure and pharmaceutical action. Fluorine in Medicinal Chemistry and Chemical Biology will serve as an excellent reference source for graduate students as well as academic and industrial researchers who want to take advantage of fluorine in biomedical research.

Book Description
Volume 4 focuses on additions and the resulting substitutions at carbon-carbon &pgr;-bonds. Part 1 includes processes generally considered as simple polar reactions, reactive electrophiles and nucleophiles adding to alkenes and alkynes. A major topic is Michael-type addition to electron deficient &pgr;-bonds, featured in the first six chapters. In part 2 are collected the four general processes leading to nucleophilic aromatic substitution, including radical chain processes and transition metal activation through to &pgr;-complexation. Metal-activated addition (generally by nucleophiles) to alkenes and polyenes is presented in part 3, including allylic alkylation catalyzed by palladium. The coverage of nonpolar additions in part 4 includes radical additions, organometal addition (Heck reaction), carbene addition, and 1,3-dipolar cycloadditions.
