Available in PDF, EPUB and Kindle. Book excerpt: Modern Applications of Cycloaddition Chemistry examines this area of organic chemistry, with special attention paid to cycloadditions in synthetic and mechanistic applications in modern organic chemistry. While many books dedicated to cycloaddition reactions deal with the synthesis of heterocycles, general applications, specific applications in natural product synthesis, and the use of a class of organic compounds, this work sheds new light on pericyclic reactions by demonstrating how these valuable tools elegantly solve synthetic and mechanistic problems. The work examines how pericyclic reactions have been extensively applied to different chemistry areas, such as chemical biology, biological processes, catalyzed cycloaddition reactions, and more. This work will be useful for organic chemists who deal with organic chemistry, medicinal chemistry, agrochemistry and material chemistry. - Provides details on the synthesis of antiviral and anticancer compounds, marking the key role of unconventional catalyzed cycloaddition reactions for preparing new derivatives in a unique reaction pathway that is scalable in industrial processes - Contains the most up-to-date review of the use of pericyclic reactions in drug delivery - Includes the enzyme-catalyzed processes involving cycloaddition reactions for different targets, demonstrating that cycloaddition is more common in nature than expected - Features new applications for cycloadditions in material chemistry and provides a general view of the most recent results in the area

Download or read book Retrosynthetic Analysis and Synthesis of Natural Products 1 written by Olivier Piva and published by John Wiley & Sons. This book was released on 2019-12-12 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: For chemists, attempting to mimic nature by synthesizing complex natural products from raw material is a challenge that is fraught with pitfalls. To tackle this unique but potentially rewarding task, researchers can rely on well-established reactions and methods of practice, or apply their own synthesis methods to verify their potential. Whatever the goal and its complexity, there are multiple ways of achieving it. We must now establish a strategic and effective plan that requires the minimum number of steps, but lends itself to widespread use. This book is structured around the study of a dozen target products (butyrolactone, macrolide, indole compound, cyclobutanic terpene, spiro- and polycyclic derivatives, etc.). For each product, the different disconnections are presented and the associated syntheses are analyzed step by step. The key reactions are described explicitly, followed by diagrams showing the range of impact of certain transformations. This set of data alone is conducive to understanding syntheses and indulging in this difficult, but worthwhile activity.

Available in PDF, EPUB and Kindle. Book excerpt: The Pauson-Khand reaction is an important reaction in the field of organic chemistry. It involves the transition-metal catalysed cycloaddition of an alkyne, an alkene and carbon monoxide, to produce cyclopentenones. The importance of this reaction originates from its high value in transforming simple components into the synthetically useful cyclopentenone unit, in which a high degree of molecular complexity can be achieved in a single step, with impressive stereochemical and regiochemical control. The Pauson-Khand Reaction investigates the nature and many variations of this reaction. Topics covered include: the mechanisms of Pauson‐Khand-type reactions non chiral intramolecular and intermolecular versions of Pauson‐Khand reactions asymmetric Pauson‐Khand reaction using chiral auxiliaries the enantioselective Pauson‐Khand reaction Pauson‐Khand reactions catalysed by metals other than cobalt unconventional Pauson‐Khand reactions the Pauson‐Khand reaction in total synthesis Presenting a comprehensive overview of this fundamental reaction, The Pauson-Khand Reaction will find a place on the bookshelves of any organic or organometallic chemist.

Available in PDF, EPUB and Kindle. Book excerpt: The use of water as a medium for promoting organic reactions has been rather neglected in the development of organic synthesis, despite the fact that it is the solvent in which almost all biochemical processes take place. Chemists have only recently started to appreciate the enormous potential water has to offer in the development of new synthetic reactions and strategies, where it can offer benefits in both unique chemistry and reduced environmental impact. In this new book, the editor, well known for his contribution to the development of water as a useful medium in synthetic organic chemistry, has assembled an international team of authors, themselves at the forefront of research into the use of the unique properties of water carrying out organic transformations, to provide a timely and concise overview of current research. By focusing on the practical use of water in synthetic organic chemistry, and with the concern for the use of solvents in organic chemistry, professional chemists, particularly those involved in industrial research and development, will find this book an essential guide to the current state of the art, and a useful starting point in their own research. Academic chemists, including postgraduate and advanced undergraduate students, will find this book an invaluable guide to this exciting and important area of chemistry.

Download or read book The Double 3 2 Photocycloaddition Reaction written by Jason A. Woolford and published by Springer Science & Business Media. This book was released on 2011-08-30 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jason Woolford's thesis describes for the first time, a double [3+2] photocycloaddition of alkenes onto aromatic rings. Modern synthetic chemistry relies on the ability of researchers to uncover new and more efficient ways of creating highly complex structures. This work describes a novel, environmentally friendly photochemical step that converts in one pot, trivial starting materials into otherwise difficult to construct fenstrane frameworks. The rigid cores of these frameworks have significant potential in drug design. Moreover, the novelty of this work overtakes many other methods for the creation of chiral centres. No less than seven chiral centres are created in the photochemical step together with the formation of four carbon-carbon bonds and multifused rings. Jason's innovative work has been the subject of several publications in peer-reviewed journals.
