Volumes in the Proven Synthetic Methods Series address the concerns many chemists have regarding irreproducibility of synthetic protocols, lack of identification and characterization data for new compounds, and inflated yields reported in chemical communications-trends that have recently become a serious problem. Featuring contributions from world-renowned experts and overseen by a highly respected series editor, Carbohydrate Chemistry: Proven Synthetic Methods, Volume 4 compiles reliable synthetic methods and protocols for the preparation of intermediates for carbohydrate synthesis or other uses in the glycosciences. Exploring carbohydrate chemistry from both the academic and industrial points of view, this unique resource brings together useful information into one convenient reference. The series is unique among other synthetic literature in the carbohydrate field in that, to ensure reproducibility, an independent checker has verified the experimental parts involved by repeating the protocols or using the methods. The book includes new or more detailed versions of previously published protocols as well as those published in not readily available journals. The essential characteristics of the protocols presented are reliability, updated characterization data for newly synthesized substances and the expectation of wide utility in the carbohydrate field. The protocols presented will be of wide use to a broad range of readers in the carbohydrate field and the life sciences, including undergraduates taking carbohydrate workshops.

Nitroalkenes have often been referred to as "synthetic chameleons" owing to their reactivity, synthetic utility and biological significance. In the last two decades, the reactivity of nitroalkenes as substrates in diverse catalytic asymmetric transformations has been of tremendous interest on account of the powerful abilities of the nitro group to coordinate and withdraw electrons, as well as its amenability to undergo a wide variety of synthetic transformations. Although numerous original articles and reviews have appeared in the literature, a monograph providing a comprehensive coverage of this topic was conspicuous by its absence. This book features: A systematic, up-to-date, in-depth and well-organized compilation, spread over 12 chapters, of various catalytic asymmetric reactions of nitroalkenes with diverse substrates reported to date A wide coverage of reactions such as Michael additions, Friedel-Crafts reactions, cycloadditions, asymmetric reductions, multicomponent and cascade reactions, as well as other miscellaneous reactions Various chiral organo, metal and even biocatalysts involved in the stereoselective synthesis of multifunctional adducts via catalytic asymmetric reactions of nitroalkenes Schemes and figures detailing all the reagents, reaction conditions and product profiles Mechanistic details, including transition state models, which will be useful for effective catalytic design This book will be an invaluable resource for those who are working in the area of asymmetric catalysis and synthetic methodologies.

This book classifies methods of synthesizing a heterocyclic ring which is fused to another ring. Classification is based on the functional group or groups present in the substrate, each chapter being devoted to the reactions of a particular pair of groups. The groups are arranged alphabetically so that they can be found easily. The book enables the reader to locate references (over 2000 are included) to the conversion of a wide variety of functional groups into heterocyclic rings of five to eight atoms. Each cyclization is shown as an equation which contains concise details or reagents, conditions, and yields. Since the classification of each cyclization is based on the functional groups involved, locating the relevant reference is independent of the identity of the ring in the substrate. This simplifies the search for the relevant reference.

This book is not only an indispensable resource for advanced undergraduate and graduate students studying the stereochemical aspects of organic reactions, but also a good reference book for all organic chemists in both industry and academia.

This timely book provides a succinct summary of methods for the synthesis of bioactive heterocycles using a multicomponent reaction (MCR) approach. The majority of pharmaceuticals and biologically active agrochemicals are heterocycles while countless additives and modifiers used in industrial applications are heterocyclic in nature. With the recent introduction of high-throughput biological evaluation, the importance of MCRs for drug discovery has been recognized and considerable efforts have been focused especially on the design and development of multi-component procedures for the generation of various bioactive heterocycles due to their significant therapeutic potential.

This book focuses on thielocin B1 (TB1), which was found to be an inhibitor of protein-protein interactions (PPIs) of proteasome assembling chaperone (PAC) 3 homodimer, and elucidates the mechanism by nuclear magnetic resonance (NMR) studies. Interfaces of PPIs recently have been expected to be novel therapeutic targets, while it is difficult to apply conventional methodology based on lock and key theory. The author achieved the first total synthesis of TB1 and its spin-labeled derivative to carry out NMR experiments because the supply of TB1 from natural sources was limited. Unique 2,2',6,6'-tetrasubstituted diphenyl ether moiety of TB1 was synthesized from a depsidone skeleton by chemoselective reduction of lactone. In the process of elongating side wings, efficient formylation utilizing dichloromethyl methyl ether-silver trifluoromethanesulfonate was developed for the sterically hindered aromatic compound. NMR titration experiments and paramagnetic relaxation enhancement observation of PAC3 homodimer were performed with synthesized TB1 and its molecular probe, respectively. The results of the above NMR studies and additional in silico docking studies suggested that TB1 promotes the dissociation to monomeric PAC3 after interaction with PAC3 homodimer. The rare mechanism shown in this book indicates a potential novel drug target in the interfaces of PPIs with no cavity or groove.

In this book, the author determines that a surface is itself a new material for chemical reaction, and the reaction of the surface provides additional new materials on that surface. The revelation of that peculiarity is what makes this book different from an ordinary textbook, and this new point of view will help to provide a new impetus when graduate students and researchers consider their results. The reaction of surface atoms provides additional new compounds, but these compounds cannot be detached from the surface. Some compounds are passive, but others work as catalysts. One superior feature of the surface is the dynamic cooperation of two or more different functional materials or sites on the same surface. This fact has been well established in the preferential oxidation of CO on platinum supported on a carbon nanotube with Ni-MgO at its terminal end. The Pt and Ni-MgO are perfectly separated, but these two are indispensable for the selective oxidation of CO in H2, where the H2O molecule plays a key role. The reader will understand that the complexity of catalysis is due to the complexity of the dynamic processes on the surface.
