Current Trends In Organic Synthesis

The last two decades have seen a rapid growth in the synthetic processing of both simple and complex molecules, aimed at meeting the needs of society in all aspects of life. Many efforts have been devoted to the development of new biologically active compounds, new materials with innovative properties such as bio-compatibility, new catalysts that allow highly selective transformations, and technologies that facilitate the synthetic pro cesses. This book is a compendium of recent progress in all these aspects of synthetic chemistry. It collects the lectures of the XII International Conference on Organic Synthesis, held in Venice from June 28 to July 2, 1998, in which the present state of art of this discipline has been reported. The topics covered include: combinatorial chemistry, new synthetic methods, stereo selective synthesis, metal-mediated synthesis, and target oriented synthesis. The book collects the contributions, in the mentioned topics, of 43 scientists from 19 different countries. The contributions presented in the Conference as plenary lectures are reported in the first section of the book. Particular attention has been dedicated to combinatorial chemistry, a new and promising methodology for the synthesis of libraries of pharmaco logically interesting compounds in order to allow the automatic pharmacological screening of thousands of compounds. The Conference has dedicated to combinatorial chemistry a mini-symposium in which scientists from academy and companies have described the current trends of this very new technology.

Current Trends in Organic Synthesis is a collection of papers presented at the Fourth International Conference on Organic Synthesis, held in Tokyo, Japan on August 22-27, 1982. This conference brings together the significant achievements in the diversified frontier fields of organic synthesis. This book is composed of 33 chapters. The first chapters focus on the synthesis of biologically active natural compounds, including metabolites of arachidonic acid, erythromycin A, verrucarins, steroids, anthracyclines, terpenes, yeast alanine t-RNA, beta-lactam antibiotics, and palitoxin. Other chapters deal with the central problems in stereoselective and chiral synthesis, as well as processes of high degree of stereochemical control and asymmetric induction. These chapters also describe chiral pool synthesis by means of carbohydrate precursors. This book also examines the methodologies in organic synthesis using reagents with boron, aluminum, transition metals, silicon, phosphorus, and sulfur. The remaining chapters are devoted to reactions involving radical initiated ring closure, small ring hydrogenolysis, annulene synthesis, vicarious nucleophilic substitution of aromatic hydrogen, and dichlorine monoxide mediated powerful chlorination. This book is of value to organic chemists and allied scientists.

This unusual collection of 49 essays gives an overview of the trends and accomplishments of synthetic organic chemistry in recent years. Unique in its approach, it deals with almost every aspect of modern synthesis. The first part of the book describes methods and reagents, with particular emphasis on rapidly developing organometallic and biooriented procedures. In the second part, these tools are applied to the syntheses of interesting target compounds and natural compounds with remarkable physiological properties. Mechanistic discussions and retrosynthetic analyses are included. More than 1000 up-to-date references help the reader to pursue the topics highlighted here. This book gives both the active researcher and the advanced student insight into the competitive atmosphere, creativity, and resourcefulness so characteristic of organic synthesis today.

The view of organic synthesis as "a concentrated expression of predictive ability and creative capacity" was advocated in the early 1950s. A concise and readable account of the role of synthesis in modern science, Organic Synthesis: The Science Behind the Art presents the general ideology of pursuits in the area of organic synthesis, and examines the methodologies that have evolved in the search for solutions to synthetic problems. This unique book details outstanding achievements of modern organic synthesis, not only for their scientific merits, but also for the aesthetic appeal of the target molecules chosen and the intrinsic beauty of the solutions to the problems posed. By judicious selection of data covering the main areas of synthetic explorations, this book serves to illustrate both the evolution of well-known approaches as well as recently emerged trends most likely to determine the future development of organic synthesis. Special attention is given to the consideration of principles of molecular design in promising and challenging areas of current research. Primarily aimed at advanced undergraduate and graduate students, Organic Synthesis: The Science Behind the Art will also be of interest to teachers, researchers and anyone requiring an introduction to the problems of organic synthesis.

A collection of articles on various topics of organic synthesis -- short, precise and topical, written by leading experts in their fields. Organic synthesis is a core subject in organic chemistry, and volumes I and II have been very successful. The topics reflect modern and up-to-date problems and research areas in organic synthesis. Readers will learn about the key synthetic strategies that are important in their daily work. A large number of references is included for each article, making the primary literature easily accessible. This is a 'must-have' book for any organic chemist, organometallic chemist, natural product chemist or graduate student.

Perfect for biochemists, synthetic and organic chemists, this book covers all important reactions, including C-C coupling reactions, oxidation reactions and many more. Divided into two parts, the first section on methodology presents new innovative methods for enzymatic catalysis optimization, including such new trends as medium engineering, directed evolution and computer-aided prediction of enantioselectivity. The second and main section deals with applications to synthesis, showing important reaction types and their applications. Only those reactions with very high selectivity are presented, allowing readers to improve their own reaction yields.

Like its predecessor, Organic Synthesis Highlights II surveys recent accomplishments and current trends in synthetic organic chemistry. Part I describes new methods and reagents including asymmetric carbon-carbon bond formation with metallocenes and with enzymes, via temporary silicon connections, and by means of carbohydrate complexes. Part II describes landmarks in the synthesis of natural products and surveys synthetic strategies to different classes of natural products. The forty essays in this volume bear witness to the creativity and talent which have led to the recent advances in the field. Both advanced students and researchers active in the field will welcome this as a source of ideas and inspiration.

The synthesis of molecules having diverse uses in medicines, agrochemicals and biomolecules are dealt with in organic chemistry. The basic concern of the industries producing such chemicals is the type of reaction involved and the percentage of yield etc. so that synthesis becomes cost effective giving special attention to ensure that there is no environmental pollution. All these considerations form the basis of green chemistry - the pressing need of the world. This book describes the methodologies/technologies to carry out green synthesis, which is extremely important for industries and also for chemical laboratories. The main features discussed are: Designing a green synthesis; Basic principles of green chemistry; Prevention of environmental pollution; Microwave induced and ultrasound assisted green synthesis; Organic synthesis in aqueous phase and solid phase; Use of green reagents, green catalysts and green solvents. £/LIST£ Senior graduates, postgraduates, teachers, researchers and scientists in their respective fields will find this book of immense use.
