The many exciting advances made in asymmetric synthesis over the past two decades have been due, in great part, to applications of tartaric and malic acid derivatives. Because of their unparalleled usefulness in synthesizing nonracemic acyclic and heterocyclic compounds, tartaric and malic acids are now considered indispensable "tools of the trade" for chemists working in natural products, fine chemicals, and pharmaceutical research.
Tartaric and Malic Acids in Synthesis provides chemists with a concise, yet comprehensive, review of the chemical properties and synthetic applications of derivatives of tartaric and malic acids. Intended as a source of information and inspiration, it contains a gold mine of ideas on the use of tartaric and malic acids in synthesis not only as chiral building blocks, but as chiral ligands, auxiliaries, and resolving agents as well. Throughout, the primary focus is on four-carbon building blocks derived from tartaric and malic acids and their synthetically useful reactions. Designed for ready reference, this book follows a simple, hierarchical organization-moving from derivatives of carboxy groups to derivatives of hydroxy groups, and, finally, to products of reduction of the carboxy groups-and includes:
* Hundreds of reaction schemes and figures.
* More than 70 tables with data and references for 2,000 compounds.
* Over 2,500 references to primary, secondary, and patent literature sources.
Tartaric and Malic Acids in Synthesis is a valuable working resource for chemists involved in the design of enantioselective syntheses. It is also an excellent supplementary text for graduate students of synthetic organic chemistry and naturalproducts chemistry.

In 1912, the Chemistry Nobel Prize was awarded for the discovery of the so-called Grignard reagents. Nowadays, many transition metal variants are developed to modify reactivity and selectivity of the C-C bond formation reaction. The Grignard reaction is one of the fundamental organometallic reactions, often used in alcohol syntheses. With transition metals like iron, cobalt and nickel or with noble metals like copper, silver and palladium, modern Grignard reagents can be designed in reactivity, selectivity and functional group tolerance. This book, written by international experts, presents an overview on timely Grignard chemistry involving transition metals.

Quality Determinants In Coffee Production presents a comprehensive overview of the main determinants of coffee quality during processing. Authored by members of the Laboratory for Analysis and Research in Coffee at the Federal Institute of Espirito Santo, the chapters in this text explain how coffee quality can be affected through each step of the main processing methods. The first section explores the history of coffee processing, covering how the processes and techniques of sensorial analysis have developed. The second section covers the evolution of these techniques and how various complexities can affect their use, plus the statistical tools that are used to increase test accuracy. Another section focuses on the relationship between fruit microbiology and coffee quality, promoting an understanding of how yeasts, fungi and bacteria effect the quality of coffee during processing. Another section is dedicated to the biotechnological processes used in coffee production, including the applicability of induced and spontaneous routes from the manipulation of raw material, the relationship between wet processing and spontaneous fermentation and the construction of sensorial routes. A final section explores volatile coffee compounds and gas chromatography techniques, including chemical and sensory maps. The majority of the reference works published on coffee processing have a pragmatic approach covering production, harvesting, post-harvesting and marketing. This work goes beyond these subjects, covering the factors that impact quality and how they lead to either qualitative reduction or gains during processing. New technological and scientific indicators for the modification and the creation of sensory routes are extensively covered, as are the international protocols used in the sensorial analysis of coffee. With its broad approach, this text presents a multidisciplinary perspective connecting areas such as statistics, biochemistry, analytical chemistry and microbiology to the results of sensory analysis using different technologies and processes. A direct relationship between these factors is established in order to help researchers understand their combined effect on coffee quality during processing.

There have been many great advances in the field of biomedical imaging in recent years, with supramolecular chemistry playing a key role in the evolution of modern imaging techniques. Non-covalent supramolecular interactions are fundamental to countless biological processes, from host-guest binding to the stabilisation of complex structures. Supramolecular chemistry techniques can be employed to create probes that can be targeted to either exploit or disrupt these interactions, giving the potential for both diagnostic and therapeutic effects. Furthermore, in techniques such as contrast enhanced MRI, controlling the interactions between solvent molecules and the imaging agent is crucial to the development of the technique. With rapid growth in the synthesis and study of molecular imaging agents, the understanding of their associated techniques has sometimes lagged behind. Supramolecular Chemistry in Biomedical Imaging will fill this gap by clarifying the state of current understanding and the nature of the underlying problems inherent to addressing problems in biology. It will cover both the techniques used in imaging and the molecular and supramolecular systems used to exploit them. This publication targets academics coming to the field from mainstream supramolecular chemistry, research graduates and undergraduates interested in supramolecular chemistry, synthesis or imaging agents and imaging techniques for biomedical applications.

During recent years, stereochemistry has undergone a phenomenal growth both in theory and practice, with a concomitant increase of interest among the organic chemists, biological chemists, medicinal chemists, and pharmacologists. The present text provides an up-to-date, coherent, and comprehensive account of the subject starting from the fundamentals and leading up to the latest developments as far as practicable. Emphasis has been placed on a symmetry-based approach to molecular chirality, stereochemical terminologies (modern stereochemistry is replete with them), topicity and prostereoisomerism, conformational analysis, dynamic stereochemistry, chiroptical properties, and assignment of absolute configuration to chiral molecules. Dynamic stereochemistry has been discussed with reference to conformation-reactivity correlation, stereoselective synthesis, and pericyclic reactions. A large crosssection of organic reactions with stereochemical implication has been incorporated. Attempts have been made to familiarise the readers with modern instrumental techniques, nuclear magnetic resonance in particular, used for stereochemical investigation. Each chapter is provided with a summary which highlights the main points of the text.

This volume is devoted to compounds in which the spiro centre is part of a pyranoid or furanoid or an iminosugar ring. The chapters contributed deal with methodological peculiarities of syntheses of natural and artificial sugar derived spirocycles as well as their biological applications and other utilities including marketed drugs. Carbohydrates are ubiquitous molecules in nature and participate in a vast number of biological interactions. Especially their conjugates with practically all kinds of primary and secondary metabolic small molecules (and also biomacromolecules) representing valuable tools for glycobiology research and also lead compounds for drug discovery. While monosaccharides per se appear as heterocycles, their natural conjugates frequently exhibit spiro(hetero)cyclic derivatives, in many cases of high therapeutical relevance. As a consequence, the field of carbohydrate-spiro-heterocycles attracts intense interest from both chemical and biomedical aspects therefore this volume will be of interest for synthetic and medicinal chemists and (glyco)biologists, as well as researchers involved in various biomedical fields.

For some 50 years, Professor Asakawa and his group have focused their research on the chemical constituents of bryophytes and have found that these plants contain large numbers of secondary metabolites, such as terpenoids, acetogenins, and aromatic compounds representative of many new skeletons, which exhibit interesting biological activities. Individual terpenoids, when found as constituents of both a bryophyte and a higher plant, tend to occur in different enantiomeric forms. Professor Asakawa has covered the literature on bryophytes in two earlier volumes of "Progress in the Chemistry of Organic Natural Products," namely, Volumes 42 (1982) and 65 (1995). Since the publication of the latter volume, a great deal of new information has appeared on bryophytes. One example is that known sex pheromones of algae have been discovered in two liverworts, indicating that some members of the latter taxonomic group might originate from brown algae. From information provided in this volume, it is suggested that two orders of the Marchantiophyta should be combined.
