The first reports on the application of microwaves in organicsynthesis date back to 1986, but it was not until the recentintroduction of specifically designed and constructed equipment,which countered the safety and reproducibility concerns, thatsynthetic application of microwaves has become established as alaboratory technique. Microwave assisted synthesis is now beingadopted in many industrial and academic laboratories to takeadvantage of the novel chemistry that can be carried out using avariety of organic reaction types. This book demonstrates the underlying principles of microwavedielectric heating and, by reference to a range of organic reactiontypes, it's effective use in synthetic organic chemistry. Toillustrate the impact microwave assisted organic synthesis can haveon chemical research, case studies drawn mainly from thepharmaceutical industry are presented.

The large-scale production of chemicals to meet various societal needs has created environmental pollution, including pollution from byproducts and improper disposal of waste. With the world facing adverse consequences due to this pollution, green chemistry is increasingly being viewed as a means to address this concern. Since most organic syntheses require toxic solvents, more reaction time, and drastic conditions of temperature, conventional methods of organic synthesis are less preferred. Microwave-assisted organic synthesis is considered to be a promising green chemical approach because it reduces reaction time from days or hours to minutes or even seconds, and has many other advantages. It helps reduce side reactions and increase yields, uses fewer solvents or is almost solvent-free, has solid supported reactions, and improves purity. This book’s main focus is microwave-assisted organic synthesis processes, particularly various reactions such as cycloaddition, rearrangement, elimination, substitution, oxidation, reduction, condensation, coupling, polymerization, nanomaterials, synthesis of heterocycles, and industrial applications under microwave irradiation. The time is not far off when this methodology will virtually replace existing and cumbersome methods of organic synthesis.

If the source materials and products fail to withstand the usually long reaction times at high temperatures and decompose, the yield is normally reduced. Therefore, the demand for increasingly clean and efficient chemical syntheses is continuously becoming more urgent from both an economic and an environmental standpoint. So-called green technologies are looking for alternative ways to reduce such drastic prerequisites for reactions. It is against this background that microwave technology has developed all the more into a powerful alternative that can be applied to practically the whole spectrum of organic synthesis. This volume brings together the latest developments in this fascinating field, supplemented by numerous practical tips, and thus provides those working in both research and industry with an indispensable source of information.

Microwave-assisted Organic Synthesis: One Hundred Reaction Procedures provides readers with a broad overview of microwave assisted Organic Synthesis, enabling students and researchers alike to produce more efficient and high yield syntheses while saving time and resources. The work addresses key problems faced by chemistry laboratories in academia and in industry, that of an ever increasing need for procedures which are low-waste, energy efficient, high yield, occur over a short reaction period, and use environmentally friendly solvents. All these factors play an important role in the development of Green Chemistry methods, and in this, Microwave-assisted Organic Synthesis: One Hundred Reaction Procedures is an excellent resource for any library. Provides a broad overview of microwave enhanced chemistry Extensive references to the source of each procedure, including equipment used, full operating procedure, and associated hazards Includes exercises and worked problems which can support more independent study

Tailored to the needs of medicinal and natural products chemists, the second edition of this unique handbook brings the contents up to speed, almost doubling the amount of chemical information with an additional volume. As in the predecessor, a short introductory section covers the theoretical background and evaluates currently available instrumentation and equipment. The main part of the book then goes on to systematically survey the complete range of published microwave-assisted synthesis methods from their beginnings in the 1990s to mid-2011, drawing on data from more than 5,000 reports and publications. Throughout, the focus is on those reactions, reagents and reaction conditions that work, and that are the most relevant for medicinal and natural products chemistry. A much expanded section is devoted to combinatorial, highthroughput and flow chemistry methods.

An updated overview of the rapidly developing field of green techniques for organic synthesis and medicinal chemistry Green chemistry remains a high priority in modern organic synthesis and pharmaceutical R&D, with important environmental and economic implications. This book presents comprehensive coverage of green chemistry techniques for organic and medicinal chemistry applications, summarizing the available new technologies, analyzing each technique’s features and green chemistry characteristics, and providing examples to demonstrate applications for green organic synthesis and medicinal chemistry. The extensively revised edition of Green Techniques for Organic Synthesis and Medicinal Chemistry includes 7 entirely new chapters on topics including green chemistry and innovation, green chemistry metrics, green chemistry and biological drugs, and the business case for green chemistry in the generic pharmaceutical industry. It is divided into 4 parts. The first part introduces readers to the concepts of green chemistry and green engineering, global environmental regulations, green analytical chemistry, green solvents, and green chemistry metrics. The other three sections cover green catalysis, green synthetic techniques, and green techniques and strategies in the pharmaceutical industry. Includes more than 30% new and updated material—plus seven brand new chapters Edited by highly regarded experts in the field (Berkeley Cue is one of the fathers of Green Chemistry in Pharma) with backgrounds in academia and industry Brings together a team of international authors from academia, industry, government agencies, and consultancies (including John Warner, one of the founders of the field of Green Chemistry) Green Techniques for Organic Synthesis and Medicinal Chemistry, Second Edition is an essential resource on green chemistry technologies for academic researchers, R&D professionals, and students working in organic chemistry and medicinal chemistry.
