Book Description
The widespread use of organoboron compounds justifies the efforts devoted to their synthesis, as well as toward developing an understanding of their reactivity. The nature of the mono- or diboron species is of paramount importance in determining the reversible covalent binding properties of the boron atom with both nucleophiles and electrophiles. By wedding the rich chemical potential of organoboron compounds to the ubiquity of organic scaffolds, advanced borylation reactions have the potential to open unprecedented synthetic alternatives, and new knowledge in the field should encourage chemists to use organoboron compounds. In this volume, the main objective is to provide a collection of the most useful, practical, and reliable methods, reported mainly within the last decade, for boron activation and boron reactivity. The volume covers the main concepts of organoboron compounds and includes experimental procedures, enabling newcomers to the field the instant and reliable application of the new tools in synthesis. Rather than aiming for a comprehensive coverage, the most advanced solutions for challenging transformations are introduced. To this end, a team of pioneers and leaders in the field have been assembled who discuss both the practical and conceptual aspects of this rapidly growing field.

Book Description
The aim of this work is to convey the practice, power, and potential of flow chemistry to a larger audience. An emerging and strengthening trend is that flow chemistry is much more than the adaption of batch processes to flow systems. Rather, flow chemistry offers a new paradigm in the way we think about chemical synthesis. This volume demonstrates the enabling power of continuous flow to access new reaction types and different chemistry space and, to this end, it has been compiled by a team of pioneers and leaders, who present both the practical and conceptual aspects of this rapidly growing field. Included are the principles of reactor design, automation, and separations/purifications in flow systems, applications in photochemistry, electrochemistry, gaseous systems, immobilized reagents and catalysts, and multistep processes. The synthesis of peptides, carbohydrates, and pharmaceuticals is covered and several chapters give insight into the use of flow in an industrial context.

Book Description
This volume, number 23 in the "Tetrahedron Organic Chemistry" series, presents organolithium chemistry from the perspective of a synthetic organic chemist, drawing from the synthetic literature to present a unified overview of how organolithiums can be used to make molecules. The development of methods for the regioselective synthesis of organolithiums has replaced their image of indiscriminate high reactivity with one of controllable and subtle selectivity. Organolithium chemistry has a central role in the selective construction of C-C bonds in both simple and complex molecules, and for example has arguably overtaken aromatic electrophilic substitution as the most powerful method for regioselective functionalisation of aromatic rings. The twin themes of reactivity and selectivity run through the book, which reviews the ways by which organolithiums may be formed and the ways in which they react. Topics include advances in directed metallation, reductive lithiation and organolithium cyclisation reactions, along with a discussion of organolithium stereochemistry and the role played by ligands such as (-)-sparteine.

Book Description
The field of dual catalysis has developed rapidly over the last decade, and these volumes define its impact on organic synthesis. The most important, basic concepts of synergistic, dual catalytic cycles are introduced, providing newcomers to the field with reliable information on this new approach to facilitating the synthesis of organic molecules. Background information and reliable procedures for challenging transformations in synthesis are presented, applying the concept of cooperative dual catalysis as a means of increasing molecular complexity in the most efficient manner. The most useful, practical, and reliable methods for dual catalysis combining metal catalysts, organocatalysts, photocatalysts, and biocatalysts are presented.

Book Description
The development of catalytic systems for the oxidation of organic compounds continues to be of great importance. There is an ongoing and increasing demand for methods that are selective, proceed under mild conditions, and adhere to green chemistry principles. "Science of Synthesis: Catalytic Oxidation in Organic Synthesis" includes the latest developments in the field, as well as selective coverage of more well-established methods. Systems based on metal catalysts, organocatalysts, and biomimetic oxidation are covered, and there is a particular focus on asymmetric processes. Scope, limitations, and mechanism of the reactions are discussed and key experimental procedures are included. Typical examples of target synthesis are often provided to show the utility and inspire further applications.

Book Description
There is a vast and often bewildering array of synthetic methods and reagents available to organic chemists today. The Best Synthetic Methods series allows the practising synthetic chemist to choose between all the alternatives and assess their real advantages and limitations. Each chapter in Carbohydrates details a particular theme associated with carbohydrate synthesis. A brief review of the subject area is provided, but the emphasis in all cases is on describing efficient practical methods to effect the transformations described. In order for the roles of carbohydrates to be thoroughly analysed and assessed, glycobiologists require access to defined target carbohydrates in useful quantities. Thus carbohydrates and glycoconjugates are now recognized as important targets for total synthesis programmes and it is essential to develop efficient regio- and stereoselective methods for the synthesis of carbohydrates. Whilst carbohydrates can sometimes be isolated from natural sources, synthetic strategies often offer the advantage of allowing access to larger quantities of material as well as entry to analogues of the natural carbohydrates. - The latest volume in the long standing Best Synthetic Methods series - Clear chapter by chapter breakdown of carbohydrate synthesis themes with examples of good practical methods for common carbohydrate syntheses
