Download Ring-Chain Tautomerism Book in PDF, ePub and Kindle
After studying ring-chain tautomerism of keto ami des and related derivatives of functionalized carboxylic acids for more than ten years, the authors consider it useful to summarize available results on these prototropic equilibria. First attempts to systematize the material were published by Jones in 1963 (Chapter 1, ref. 11). Much, sometimes contradictory, experimental data were scattered about the literature at that time; spectroscopic methods, applied to this field during the last two decades, were needed to revise several previous concepts. In the following years special aspects of ring-chain tautomerism have been discussed occasionally, but no attempt was previously made to cover the whole field. This review is designed to provide a comprehensive compilation of ring-chain tautomerism with one exception: carbohydrates which have already been treated repeatedly, have been omitted. The book is based on a monograph published in Russian: R. E. Valters, Ring-Chain Isomerism in Organic Chemistry. Zinatne. Riga, 1978. There fore, the arrangement and development of the theme is due mainly to one of the authors (R.E.Y.). In the present work the literature has been covered until the end of 1982.

Download Green Approaches in Medicinal Chemistry for Sustainable Drug Design Book in PDF, ePub and Kindle
Extensive experimentation and high failure rates are a well-recognized downside to the drug discovery process, with the resultant high levels of inefficiency and waste producing a negative environmental impact. Sustainable and Green Approaches in Medicinal Chemistry 2e reveals how medicinal chemistry can play a direct role in addressing this issue. After providing essential context to the growth of green chemistry in relation to drug discovery, the book goes on to identify a broad range of practical techniques and useful insights, revealing how medicinal chemistry techniques can be used to improve efficiency, mitigate failure and increase the environmental benignity of the entire drug discovery process. Drawing on the knowledge of a global team of experts, Sustainable and Green Approaches in Medicinal Chemistry, Second Edition encourages the growth of green medicinal chemistry, and supports medicinal chemists, drug discovery researchers, pharmacologists and all those in related fields across both academia and industry in integrating these approaches into their own work. This second volume of the second edition includes the development of nanoparticles and nanocomposites, as well as the application of ultrasound and microwave-induced methods; studies solventless synthesis; defines the role of steroids; studies reactions in aqueous solution; identifies enzyme-mediated reactions; investigates ionic liquids and deep eutectic solvents; explores natural products; investigates solid supports; realizes the effects of salts; focuses on combinatorial chemistry; develops one-pot methods; analyzes multi-component reactions; investigates dipole moment values; and examines computer-assisted methods. Highlights the need for adoption of sustainable and green chemistry pathways in drug development Reveals risk factors associated with the drug development process and the ways sustainable approaches can help address these Identifies novel and cost effective green medicinal chemistry approaches for improved efficiency and sustainability

Download Hetero Diels-Alder Methodology in Organic Synthesis Book in PDF, ePub and Kindle
Organic Chemistry: A Series of Monographs, Volume 47: Hetero Diels-Alder Methodology in Organic Synthesis focuses on the use of hetero Diels-Alder reactions as pivotal steps in natural product total syntheses. The publication first offers information on N-sulfinyl compounds and sulfur diimides and imino dienophiles. Discussions focus on sulfur dioxide and related compounds, selenium dioxide, sulfur diimide cycloadditions, regiochemical, stereochemical, and mechanistic aspects, iminium salts and neutral imines, oximino compounds, and intramolecular cycloadditions. The text then takes a look at nitroso and thionitroso dienophiles and carbonyl dienophiles. The manuscript elaborates on thiocarbonyl and selenocarbonyl dienophiles and miscellaneous dienophiles. Topics include nitriles, azo compounds, selenoaldehydes, thioketones, thioesters, dithioesters, and related compounds, and thiophosgene and related compounds. The text also ponders on oxabutadienes, thiabutadienes, and azabutadienes. The publication is a valuable reference for chemists and readers interested in the Hetero Diels-Alder methodology.
