    The explosive growth of organoselenium chemistry over the past 12 years can be attributed to the specific properties of organic selenium molecules, which fit the requirements of modern organic synthesis. Most of them are well adapted to chemo-, regio- and stereo-selectivities... In addition, they can be used in mild experimental conditions which are compatible with the stability of both substrates and products in the preparation of unsaturated and functional complex molecules, especially in the field of natural products. This book describes and illustrates different synthetic routes to organic structures using selenium reagents or intermediates. The approach emphasizes that such transformations are simple, efficient and often carried out at room temperature. The scope ranges from the preparation of both inorganic and organic selenium reagents, through descriptions of structure, toxicity, biological aspects and nuclear magnetic resonance, to applications of specific selenium compounds in various syntheses including natural products and biologically active compounds.

  • Biosynthesis of Aromatic Compounds

    Biosynthesis of Aromatic Compounds is a collection of papers from the Proceedings of the Second Meeting of the Federation of European Biochemical Societies in Vienna, on April 21-24, 1965. This volume is based on lectures given at the symposium and covers the studies made on the biosynthesis of aromatic compounds. The first part discusses the biosynthetic intermediates in polyketide biosynthesis in connection with the biosynthesis of fatty acids; it also notes the biosynthesis of coumarins that form from derivatives of carbohydrate metabolism. Other results concerning the biosynthesis of benzoic acids and on compounds such as substituted benzaldehydes and benzylalcohols are presented. Another paper shows that when species of mycobacteria are grown under iron-deficient conditions, salicylic acid can be produced. The second part focuses on studies made on the biosynthesis of aromatic compounds that contain hetero atoms. The formation of aromatic systems in alkaloids and the biosynthesis of some alkaloids based on aromatic precursors are analyzed. The book explains that some flavor compounds such as mustard oils are the product of enzymatic hydrolysis of thioglucosides, and then notes that the biogenetic schemes of Mentzer et al. concerning another study are not suitable as working hypotheses. This collection can be read profitably by chemists, biochemists, and academicians involved in aromatic compound researches.

    • Inglés
    Functions of Alternative Terminal Oxidases is a collection of papers from the 11th meeting of the Federation of European Biochemical Societies in Copenhagen in 1977. The book opens with a review of the alternate electron transport mechanism to the main phosphorylating respiratory chain. One paper presents the respiration of mutant stains of Neurospora crassa treated with chloramphenicol that results in three distinct pathways distinguishable by the use of inhibitors. Another paper outlines the testing methods to determine the parameters controlling cyanide-insensitive respiration in Acanthamoeba castellanii and notes the physiological function of this insensitivity. The book then explains that this phenomenon of cyanide-insensitive respiration is common among yeasts, and such pathway of electron transport to oxygen that is insensitive to cyanide or antimycin is well founded in many higher plants and microorganisms. One paper then investigates the terminal oxidases found in two stages in the life cycle of trypanosomes, which cause African sleeping sickness. Another paper notes that a study of the energy metabolism of End. magnusii, a kind of yeast, showed no glucose repression, no alternative oxidation pathway, and no cyanide-insensitive pathway was normally present. The text will be of interest to those whose work involves these organisms, and to researchers, professors, and students whose disciplines are in developmental biology, micro-biology, or cellular biology.

    • Inglés
    Piperidine, one of the simplest heterocyclic systems, is found in nature as part of several alkaloid compounds. Both natural and especially unnatural piperidine derivatives present interesting pharmacological properties. From a structural viewpoint, the conformation of piperidine has been the subject of one of the fiercest controversies in structural organic chemistry in the last few years. As a result of the combined use of several spectroscopic techniques, the conformational behavior of most types of piperidine-related compounds has been clarified. Some piperidine derivatives, namely, N-acylpiperidine, &agr;-cyanopiper... and piperidones are extremely useful and versatile intermediates in organic synthesis. The present book offers an updated and integrated view of all these topics. The aim of the book is twofold. Firstly, to reveal to the reader the combined use of different spectroscopic data, to facilitate an insight into the structure and conformational properties of any new piperidine derivative. Secondly, to establish a consistent link between conformation and reactivity for a variety of piperidine derivatives. Such a bridge is a key step for stereocontrol when dealing with the application of piperidine derivatives as synthetic intermediates. The book is conceived so that most of the information comes from visual inspection of the very abundant graphic material. An exhaustive subject index of more than 450 entries is also included.

  • Structure and Dynamics of Solutions

    • Inglés
    Recent advances in the study of structural and dynamic properties of solutions have provided a molecular picture of solute-solvent interactions. Although the study of thermodynamic as well as electronic properties of solutions have played a role in the development of research on the rate and mechanism of chemical reactions, such macroscopic and microscopic properties are insufficient for a deeper understanding of fast chemical and biological reactions. In order to fill the gap between the two extremes, it is necessary to know how molecules are arranged in solution and how they change their positions in both the short and long range. This book has been designed to meet these criteria.It is possible to develop a sound microscopic picture for reaction dynamics in solution without molecular-level knowledge of how reacting ionic or neutral species are solvated and how rapidly the molecular environment is changing with time. A variety of actual examples is given as to how and when modern molecular approaches can be used to solve specific solution problems. The following tools are discussed: x-ray and neutron diffraction, EXAFS, and XANES, molecular dynamics and Monte Carlo computer simulations, Raman, infrared, NMR, fluorescence, and photoelectron emission spectroscopic methods, conductance and viscosity measurements, high pressure techniques, and statistical mechanics methods. Static and dynamic properties of ionic solvation, molecular solvation, ion-pair formation, ligand exchange reactions, and typical organic solvents are useful for bridging the gap between classical thermodynamic studies and modern single-molecule studies in the gas phase.The book will be of interest to solution, physical, inorganic, analytical and structural chemists as well as to chemical kineticists.
