In the area of organic chemistry one major challenge we are currently faced with is how to assemble potentially useful molecules in new ways that generate molecular complexity and in sequences that are as efficient as possible. Our efforts in this regard, specifically for the preparation of amino containing compounds incorporating an aromatic ring, are described in this doctoral thesis. We discovered an interesting regioselectivity in an intramolecular Heck reaction, which we studied for a series of substrates that are unbiased in terms of the size of the newly formed ring, where very high levels of selectivity in relation to the new carbon-carbon bond are typically observed. DFT calculations were performed to attempt to shed light on the reaction sequence. This regioselective Heck reaction, combined with the reductive removal of the temporary amino-protecting group, allowed us to synthesize the Sceletium alkaloids: mesembrane, mesembranol and mesembrine.

"This book presents comprehensive accounts of the chemistry revolving around the sulphonamides. Sulfonamides are widely present in various drugs as a functional group and are a manmade synthetic drug. Hence, their extended research is a prerequisite for every practitioner of organic chemistry. Chapter 1 introduces the synthesis, reactivity, acidity, and pharmaceutical properties of the sulphonamides. It highlights the synthesis of biologically active sulphonamides, the study of their biological activity by QSAR method, and their medical applications. Chapter 2 deals with the classification of sulphonamides (i.e. acyclic and cyclic) and their structural activity relationship. It also describes the application of sulphonamides in pharmaceuticals as antimicrobial, anti-diabetic, anti-viral, anti-cancer, anti-inflammatory and anti-malarial agents. Chapter 3 reviews the synthetic attempts towards sulphonamide synthesis by employing the fixation of sulphur-dioxides. These approaches have been categorized into three parts: a) transition metal-catalyzed, b) employing Lewis acid, c) photocatalytic. Chapter 4 discusses the use of sulphonamides as potent organocatalysts, briefly describing how the mono- and C2-symmetric bis-sulfonamides act as efficient bifunctional and multifunctional organocatalysts in the enantioselective Michael addition of carbonyl compounds to alpha, beta-unsaturated compounds. Chapter 5 details the oxidative sulphonamidation of alkenes and dienes, which also direct the routes to the synthesis of numerous heterocycles and linear compounds. Special emphasis is given to the comparison of reactivity of triflamides, arenesulfonamides, and the deprotection of sulfonamides. Chapter 6 describes the therapeutic properties of sulphonamides, which are significantly increased by the presence of the metal ions and ligands. This complex generation provides the opportunity to exploit the unique properties of metal centers, such as multiple oxidation states, redox properties, a wide variety of coordination numbers, symmetries and structural patterns, which offer highly adaptable platforms for drug design. Chapter 7 provides an overview of the clinical applications of sulphonamides on the toxicity and pharmacokinetic aspects of various sulpha-drugs. The mechanism involved in the development of sulfonamide resistance is briefly discussed. Thus, this book summarizes important attempts undertaken by chemists and biologists worldwide in the area of sulphonamides. Most importantly, the book also correlates the structural activity relationship and the related biological activity of the sulphonamides, attracting both novice and experienced chemists across the globe"--

As little as a decade ago, radicals were regarded as interesting reactive intermediates with little synthetic use. However, recent results show that radicals have an enormous potential for applications in stereoselective reactions - it's all a matter of knowing what method to use and how to apply it. Three world experts in the field have combined their expertise and present the concepts to understand and even to predict the course of stereoselective radical reactions. In addition, guidelines are established which will enable the readers to plan and carry out their own stereoselective syntheses with radicals. A comprehensive list of references provides an easy access to the primary literature. The Stereochemistry of Radical Reactions is a highly topical introduction to this burgeoning field of research. Both advanced students and researchers active in the field will welcome this book as a source of concepts and ideas.
