Book Synopsis Syntheses and Spectral Studies of Some New Mannich Bases by : Krishan K. Khullar
Download or read book Syntheses and Spectral Studies of Some New Mannich Bases written by Krishan K. Khullar and published by . This book was released on 1966 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of 2,6-dimethylmorpholine as an amine moiety in the Mannich reaction has been investigated. Thirteen new bases have been synthesized using different ketones. The use of 2,6-dimethylmorpholine in the Mannich reaction has been extended by allowing it to react with two different phenolic compounds. The product obtained from ^-naphthol was found to have no nitrogen. Probable structures have been assigned to this compound and the mechanisms of their formation discussed. The ^-amino acids have also been synthesized by Mannich reaction. The resulting acids have been esterified by thionyl chloride and methanol to yield the corresponding /S-amino ester salts. All attempts to use 2,6-dimethylpiperidine, 2- methylpiperidine and p-chlorophenylacetic acid in the Mannich reaction have been unsuccessful. However, 3-methylpiperidine has been successfully used in the Mannich reaction. The structures of the compounds have been established by infrared spectroscopy, mass spectrometry and elemental analysis. An attempt has also been made to correlate mass spectral data with antispasmodic activity of certain Mannich bases.

Book Synopsis Quinolone Antibacterials by : Jochen Kuhlmann
Download or read book Quinolone Antibacterials written by Jochen Kuhlmann and published by Springer. This book was released on 2012-02-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been over 30 years since the first clinically important member of the quinolone class, nalidixic acid, was introduced into medical practice. The modification produced in the quinolone nucleus by introducing a fluorine at the 6-position led to the discovery of the newer fluoroquinolones with enhanced antibacterial activities as compared to nalidixic acid. By now a great deal of preclinical and clinical experience has been obtained with these agents. The intense interest in this class of antibacterial agents by chemists, micro biologists, toxicologists, pharmacologists, clinical pharmacologists, and clini cians in various disciplines encouraged us to summarize the information on the history, chemistry, mode of action and in vitro properties, kinetics and efficacy in animals, mechanisms of resistance, toxicity, clinical pharmacology, clinical experience, and future prospects in one volume of the Handbook of Experimental Pharmacology. As this series deals predominantly with "experimental" characteristics of drugs, our volume is dedicated specifically to quinolones and emphasizes principally their preclinical and clinical phar macological characteristics, despite the existence of several summaries on quinolones. The chemistry of the quinolones is described in detail. The chapter on the mode of action of quinolones reports the conclusive evidence that gyrase is the intracellular target of the quinolones; however, another enzyme, topoisomerase IV, may also be a target for quinolones, and the exact mechanisms by which quinolones act bactericidally are far from being understood.

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.
