Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Perusal of literature reveals the importance of 2,4-pyrandione derivatives, especially those substituted heterocyclic moieties at position 3 as antimicrobial agents. In conjuction with our current research with pyrandione and related compounds, we report herein on the chemistry of dehydroacetic acid that accommodates the pharmacological active moieties. However, no review article regarding the synthesis and reactions of such compound was found during the literature survey, and it is the first time to publish such review by us. 104 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This book highlighted the methods used for the synthesis of some new pyrimidine compounds. The reactivity of pyrimidine and their synthetic importance were investigated. It also reported a good introduction for the literature survey of the chemistry of pyrimidine compounds. In this context, we reported herein the behavior of simple reagents in order to obtain some new pyrimidine ring systems and its reactivity towards different reagents for the constructions of heterocyclic derivatives containing a pyrimidine moiety. The methods of synthesis and the synthetic mechanisms of the aforementioned reactions were well presented and the structures of these compounds were assessed by analytical and spectral data. This book represents the ultra violet (UV) studies including synthesis and characterization of novel azobenzenesulfonamide dyes, the effect of solvent, effect of substituents and the effect of pH. The methods, analytical and spectral data of the investigated compounds were included.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Water-in-crude oil emulsions stabilized by natural surface-active components (such as asphaltene) are one of the major problems in relation to petroleum production. New water soluble nonionic amphiphilic block and graft copolymers based on hydrophilic PEG and PPO were prepared. PEG-PPO-PEG copolymers were prepared in the normal condition by two methods to use them as demulsifiers for crude oil emulsions. The first step in this work is to polymerize propylene glycol and propylene oxide to produce poly (propylene glycol) PPO. The reaction time was adjusted to produce PPO having different molecular weights. The molecular weights of the prepared PEG-PPO-PEG block and graft copolymers were determined by GPC technique. The surface activity of the prepared surfactants was determined from the surface and thermodynamic properties of these surfactants. The evaluation of the prepared copolymers as demulsifiers for water-in-crude oil emulsions was carried out.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This book reported the literature survey of the chemistry of 2-cyanomethylbenzothiazole including the activity Syntheses and their synthetic importance. Furthermore, the obtained results were discussed, 41 novel compounds were synthesized, the synthetic mechanisms were investigated and compounds were established by elemental analysis and spectral data. The UV spectra of azo dyes provide additional evidence that such compounds have the hydrazone structure rather than the other structures. The newly synthesized compounds were screened for their antioxidant assay (ABTS method) and cytotoxicity activities against four different cell lines. Some of the compounds exhibited the promising activities. Finally, the experimental methods were included.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The aim of this book is to synthesize some novel heterocyclic compounds starting from easily obtainable enamines. Therefore, the work have been divided into two parts; the first one is the synthesis of acryclic enamine, namely 2-cyano-3-(dimethylamino)-N-(4-phenylthiazol-2-yl)acrylamide and study its behavior towards some different nucleophiles to attain polyfunctionally substituted heterocyclic system of potential pharmaceutically interest. The second part is the synthesis of aminopyrazole derivative which has a latent enamine skeleton and study its reactivity towards various types of 1,3-biselectophilic reagents to obtain annulated pyrazole derivatives which have expected pharmacological activity. The methods of synthesis and the synthetic mechanisms of the aforementioned reactions were well presented and the structures of these compounds were assessed by analytical and spectral data.…
