Available in PDF, EPUB and Kindle. Book excerpt: Guanidines, amidines and phosphazenes have been attracting attention in organic synthesis due to their potential functionality resulting from their extremely strong basicity. They are also promising catalysts because of their potential for easy molecular modification, possible recyclability, and reduced or zero toxicity. Importantly, these molecules can be derived as natural products – valuable as scientists move towards “sustainable chemistry”, where reagents and catalysts are derived from biomaterial sources. Superbases for Organic Synthesis is an essential guide to these important molecules for preparative organic synthesis. Topics covered include the following aspects: an introduction to organosuperbases physicochemical properties of organic superbases amidines and guanidines in organic synthesis phosphazene: preparation, reaction and catalytic role polymer-supported organosuperbases application of organosuperbases to total synthesis related organocatalysts: proton sponges and urea derivatives amidines and guanidines in natural products and medicines Superbases for Organic Synthesis is a comprehensive, authoritative and up-to-date guide to these important reagents for organic chemists, drug discovery researchers and those interested in the chemistry of natural products.

Download or read book Bio Based Solvents written by François Jérôme and published by John Wiley & Sons. This book was released on 2017-06-29 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multidisciplinary overview of bio-derived solvent applications, life cycle analysis, and strategies required for industrial commercialization This book provides the first and only comprehensive review of the state-of-the-science in bio-derived solvents. Drawing on their own pioneering work in the field, as well as an exhaustive survey of the world literature on the subject, the authors cover all the bases—from bio-derived solvent applications to life cycle analysis to strategies for industrial commercialization—for researchers and professional chemists working across a range of industries. In the increasingly critical area of sustainable chemistry, the search for new and better green solvents has become a top priority. Thanks to their renewability, biodegradability and low toxicity, as well as their potential to promote advantageous organic reactions, green solvents offer the promise of significantly reducing the pernicious effects of chemical processes on human health and the environment. Following an overview of the current solvents markets and the challenges and opportunities presented by bio-derived solvents, a series of dedicated chapters cover all significant classes of solvent arranged by origin and/or chemical structure. Throughout, real-world examples are used to help demonstrate the various advantages, drawbacks, and limitations of each class of solvent. Topics covered include: The commercial potential of various renewably sourced solvents, such as glycerol The various advantages and disadvantages of bio-derived versus petroleum-based solvents Renewably-sourced and waste-derived solvents in the design of eco-efficient processes Life cycle assessment and predictive methods for bio-based solvents Industrial and commercial viability of bio-based solvents now and in the years ahead Potential and limitations of methodologies involving bio-derived solvents New developments and emerging trends in the field and the shape of things to come Considering the vast potential for new and better products suggested by recent developments in this exciting field, Bio-Based Solvents will be a welcome resource among students and researchers in catalysis, organic synthesis, electrochemistry, and pharmaceuticals, as well as industrial chemists involved in manufacturing processes and formulation, and policy makers.

Download or read book Reagents for Silicon Mediated Organic Synthesis written by Philip L. Fuchs and published by John Wiley & Sons. This book was released on 2011-11-07 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last three decades the importance of organosilicon chemistry has greatly increased because it has opened a number of new synthetic strategies. Silicon reagents are usually low-cost, versatile and allow a wide range of reactions. This is the first Handbook to compile essential Silicon containing reagents and makes use of the leading reagent database e-EROS. Another hot volume in the series Handbooks of Reagents for Organic Synthesis, this is a must-have resource for all synthetic chemists working in drug development and medicinal chemistry. For the selection the Editor focussed on three key synthetic approaches with the greatest impact: 1. Use of silicon as a 'temporary tether' by unifying a reactive pair of functional groups and taking advantage of their template-biased intramolecular cyclization. 2. The specific use of the silane functionality as a hetero t-butyl group, often colloquially referred to as the use of silicon as a 'fat proton'. 3. The use of the Brook rearrangement as an 'anion relay stratagem'. A new feature in this Handbook is the reagent finder, an alphabetically organized lookup table arranged by organic functionality and specific structure of the silicon atom to which it is bound.

Download or read book Heterocyclic Compounds written by Kristian Nylund and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterocyclic compounds are organic compounds containing at least one atom of carbon, and at least one element other than carbon, such as sulphur, oxygen or nitrogen within a ring structure. These structures may comprise either simple aromatic rings or non-aromatic rings. Some examples are pyridine (C5H5N), pyrimidine (C4H4N2) and dioxane (C4H8O2). Many heterocyclic compounds, including some amines, are carcinogenic. This book details the proposed mechanisms of Gewald-like reactions and the wide scope of substituted 2-aminothiophenes for real life applications. Literary information about synthesis methods, structure, physical-chemical and biological properties is summarised, and also information about conversion of adamantyl-1 and adamantyl-2 imidazole and benzimidazole derivatives is given. In addition, 3-acetylindole derivatives have been in the centre of attention of researchers over many years due to the high practical value of these compounds. This book presents a survey of the literature on 3-acetylindoles chemistry and provides useful and up-to-date data for medicinal chemists.
