The focus of this work lies on the exploitation of hypophosphorous derivatives in order to develop new methodologies for P-C bond formation as well as synthesizing biologically relevant phosphorus compounds. A review of the work published to date from the Montchamp group is provided in Chapter 1: Much of the methodology is applied in the remainder of the thesis in reactions such as radical addition, base-promoted alkylation and cross-coupling of anilinium hypophosphite. The following chapter describes initial results of the transition-metal catalyzed cross-coupling in the presence of beta-hydrogens and with chloromethylphthalimide. The application of phosphine-borane chemistry as a phosphinylidene protecting group is discussed in Chapter 3. An in-depth literature review provides the background for the new methodology. Novel gamma-aminobutyric acid analogues are synthesized using methods developed within the Montchamp group. Their synthesis and biological evaluation are discussed in the final chapter.

Reactivity of P-H Group of Phosphorus Based Compounds bridges the gap between inorganic and organic phosphorus compounds, providing a basis to explore the myriad possibilities for synthesis of novel low and high molecular phosphorus-containing compounds. It covers well-documented reactions in detail, including: tautomerization, oxidation, reduction, alkylation, oxidation coupling, addition reaction to: carbon-carbon multiple bonds, Schiff base, isocyanates, nitriles, epoxides; addition to carbonyl group, Kabachnik- Fields reaction, cross-coupling reaction and more. In an accessible style complete with synthetic routes and figures, the resource then covers the reactivity of multiple P-H group members: phosphines, phosphine oxides, hypophosphorus acid, H-phosphinic acids and polys(alkylene H-phosphonate). This valuable coverage supports the advancement of research and applications in this area for scientists solving a scientific problem or starting a variety of new projects, such as a new reaction for the synthesis of biologically active compounds, new methods of polymer synthesis or a new methodology for polymer modification. Describes the diverse reactivity of the phosphorus-hydrogen group, perhaps the most powerful in organic chemistry Includes practical information for the synthesis of catalysts, biologically active substances, flame retardants, advance materials and polymer materials Offers a visually-accessible guide to important reactions by an internationally recognized chemist

Explores the potential of new types of anion-binding catalysts to solve challenging synthetic problems Anion-Binding Catalysis introduces readers to the use of anion-binding processes in catalytic chemical activation, exploring how this approach can contribute to the future design of novel synthetic transformations. Featuring contributions by world-renowned scientists in the field, this authoritative volume describes the structure, properties, and catalytic applications of anions as well as synthetic applications and practical analytical methods. In-depth chapters are organized by type of catalyst rather than reaction type, providing readers with an accessible overview of the existing classes of effective catalysts. The authors discuss the use of halogens as counteranions, the combination of (thio)urea and squaramide-based anion-binding with other types of organocatalysis, anion-binding catalysis by pnictogen and tetrel bonding, nucleophilic co-catalysis, anion-binding catalysis by pnictogen and tetrel bonding, and more. Helping readers appreciate and evaluate the potential of anion-binding catalysis, this timely book: Illustrates the historical development, activation mode, and importance of anion-binding in chemical catalysis Explains the analytic methods used to determine the anion-binding affinity of the catalysts Describes catalytic and synthetic applications of common NH- and OH-based hydrogen-donor catalysts as well as C-H triazole/triazolium catalysts Covers amino-catalysis involving enamine, dienamine, or iminium activation approaches Discusses new trends in the field of anion-binding catalysis, such as the combination of anion-binding with other types of catalysis Presenting the current state of the field as well as the synthetic potential of anion-binding catalysis in future, Anion-Binding Catalysis is essential reading for researchers in both academia and industry involved in organic synthesis, homogeneous catalysis, and pharmaceutical chemistry.

Significant Pharmaceuticals Reported in US Patents identifies the next generation of pharmaceuticals reported in US Patents. This "hands-on" title provides explicit laboratory methods for preparing the most recent and effective medications. Each entry documents the biological testing protocols used to evaluate a drug and the significance of the current treatment agent over previous methods. Pharmaceuticals are included in this review only if at least two of the following criteria were met: Effectiveness in treating an illness, Innovative, ease of preparation, synergy with existing Medications. Pharmaceuticals are reported for 27 separate classes of illness, including: AIDS, Alzheimer's Disease, Cardiovascular Disorders, Diabetes, Epilepsy, Hepatitis C, Osteoporosis, Obesity and Sleep Disorders. Significant Pharmaceuticals Reported in US Patents has been designed to be used as both a reference and synthetic guide for pharmaceutical, medicinal and organic chemists and graduate students. Researchers working in other areas will also find the information valuable as in many instances intermediates or the next generation pharmaceutical are readily convertible into other industrial products including: anti-oxidants, chemical additives, herbicides, polymer precursors, water purification agents. Clear structural depictions of reagents and chemical transformations have been supplied to permit the identification of other future applications. Identifies next generation pharmaceuticals Provides practical preparation methods for each active agent and derivatives Documents the analytical characterization and biological testing results of active agents

Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
