This book covers whole aspects of the sulfur isologues of amides. Starting from the synthetic methods of thioamides, a range of synthetic applications to the construction of carbon-sulfur and carbon-carbon bonds, to asymmetric reactions, to formation of heterocycles are described. Among the array of thiocarbonyl compounds, thioamides are readily handled in room temperature air. Some of their characteristic features are that the polarity of C=S bonds in thioamides is much smaller than C=O bonds in ordinary amides, that thioamides possess higher HOMO and lower LUMO when compared with those of ordinary amides, and that carbon atoms alpha to the C=S and nitrogen atoms in thioamides are more acidic than those in ordinary amides. Theoretical studies further disclose their features. Thioamides are also used as ligands to a wide variety of metals. Their unique photophysical properties and catalytic activities are described here. Characteristic features of biologically relevant thioamides, e.g., thiopeptides and related compounds, are the final focus of the book.
This thesis addresses two fundamental areas in contemporary organic chemistry: synthesis of natural products and catalytic asymmetric synthesis. Firstly, a new methodology, developed by our research group, which allows the asymmetric synthesis of lactones, a structural unit ubiquitous in natural products, was utilised in the synthesis of a number of natural product analogues that showed significant biological activity. Secondly, the development of a catalytic asymmetric synthesis of a key structural motif present in a number of natural products and pharmaceuticals was accomplished. During the course of this work we discovered dual stereo control, which is significant because it allows the configuration of a new stereo centre to be controlled by a simple change of proton source.

This book, which is the first of a series devoted to the chemistry of pyrrole and its derivatives, presents the basic structural, physical and chemical properties of 1H-pyrrole and of the less prevalent 2H-and 3H-isomers, together with the synthesis of the three systems. Since its inital detection in coal, tar and bone oil by Runge in 1834, pyrrole has been an intriguing compound; one which, although being highly susceptible to oxidation and polymerization, occupies a key role in life. Such was its importance as the basic nitrogen heterocycle in porphins and chlorins that much of our early knowledge of the simple ring system revolved around the biologically more important derivatives.
Lipid Glossary 2 is a handy reference for a wide range of lipid

Carbohydrate Chemistry provides review coverage of all publications relevant to the chemistry of monosaccharides and oligosaccharides in a given year. The amount of research in this field appearing in the organic chemical literature is increasing because of the enhanced importance of the subject, especially in areas of medicinal chemistry and biology. In no part of the field is this more apparent than in the synthesis of oligosaccharides required by scientists working in glycobiology. Clycomedicinal chemistry and its reliance on carbohydrate synthesis is now very well established, for example, by the preparation of specific carbohydrate- based antigens, especially cancer-specific oligosaccharides and glycoconjugates. Coverage of topics such as nucleosides, amino-sugars, alditols and cyclitols also covers much research of relevance to biological and medicinal chemistry. Each volume of the series brings together references to all published work in given areas of the subject and serves as a comprehensive database for the active research chemist Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.

Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.
At present, three-dimensional free-radical polymerization (TFRP) is a special ?eld of radical polymerization. TFRP is characterized by speci?c kinetic regularities and mechanisms of processes for the formation of cross-linked or hyper-branched po- mers, and they are different from the kinetics and mechanism of classical radical polymerization. The fundamental studies of kinetics and mechanism of TFRP with formation of cross-linked polymers have been carried out in three stages. The ?rst stage lasted from 1960 until 1983, and the main mechanisms of TFRP of oligo(acrylates) were established during this stage [1-3]. Condensation telomerization, being a universal oligo(acrylate) synthesis procedure, allows us to vary certain molecular parameters, such as length and ?exibility of oligomeric blocks, number and type of reactive groups (methacrylic or acrylic groups), and chemical nature of atomic groups of an oligomeric block, which represent the centers of strong intermolecular interactions. For this reason, oligo(acrylates) were very convenient compounds for establi- ing the main kinetic regularities of TFRP and regularities of formation of polymer three-dimensional cross-linkedstructures,according totheso-calledmicrohetero- neous mechanism (G.V. Korolev, 1977), at the topological and morphological levels.
This book represents the compilation of papers presented at the IFIP Working Group 8. 2 conference entitled "Information Technology in the Service Economy: Challenges st and Possibilities for the 21 Century. " The conference took place at Ryerson University, Toronto, Canada, on August 10 13, 2008. Par ticipation in the conference spanned the continents from Asia to Europe with paper submissions global in focus as well. Conference submissions included complete d research papers and research in progress reports.
