Available in PDF, EPUB and Kindle. Book excerpt: One of the problems with modern public health is target searching for new highly effective medicinal preparations. Among those medicinal preparations are the natural and synthetic origins of quinazolinone-4 derivatives. Quinazolinone derivatives are reported to be physiologically and pharmacologically active. They also exhibit a wide range of activities such as anticonvulsant, antiinflammatory, antifungal, antimalarial, and sedative properties. Some of these compounds are identified as drugs used as diuretics, vasodilators, and antihypertensive agents. Moreover, sulfonamide derivatives have been widely used as bacteriostatic agents. Prompted by the above-mentioned facts and in conjunction with our ongoing program on the utility of readily obtainable starting material for the synthesis of heterocyclic systems of biological interest, we have decided to synthesize a series of quinazolinone derivatives having sulfonamide moiety with a potentially wide spectrum of biological responses.

Download or read book Dienamine Catalysis for Organic Synthesis written by Kengadarane Anebouselvy and published by Royal Society of Chemistry. This book was released on 2018-03-02 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade a new era in asymmetric catalysis has been realised by the discovery of L-proline induced chiral enamines from carbonyls. Inspired by this, researchers have developed many other primary catalytic species in situ, more recently secondary catalytic species such as aminals have been identified for use in asymmetric synthesis. High-yielding asymmetric synthesis of bioactive and natural products through mild catalysis is an efficient approach in reaction engineering. In the early days, synthetic chemists mainly focused on the synthesis of complex molecules, with less attention on the reaction efficiency and eco-friendly conditions. Recent investigations have been directed towards the development of atom economy, eco-friendly and enantioselective synthesis for more targeted and efficient synthesis. Building on the momentum of this rapidly expanding research area, Dienamine catalysis for organic synthesis will provide a comprehensive introduction, from the preformed species, in situ generation and onto their applications in the synthesis of bioactive molecules and natural products.

This book was released on 2013 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Spectrum of Pharmaceutical Knowledge has undergone radical Changes in the last half century. Chalcones afford a facile route of access to many of the heterocyclic systems containing Oxygen and Nitrogen. An attempt is therefore made to synthesize Chalcones from 3-acetyl thiophene by reaction with either aromatic or hetero aromatic aldehydes using Claisen-Schmidt condensation. The Resulting chalcones after purification and characterisation by physical and spectral methods have been successfully converted into substituted pyrimidines and pyrazolines. Chalcones also reported to possess a number of biological activities, they were also screened for some of the activities like antiinflammatory and antimicrobial activities. These were characterised and their biological activities evaluated.All these efforts resulted in the preparation of some promising compounds with significant biological activities
