Download or read book Modern Sustainable Techniques In Total Synthesis Of Bioactive Natural Products written by Sasadhar Majhi and published by World Scientific. This book was released on 2023-04-25 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Sustainable Techniques in Total Synthesis of Bioactive Natural Products comprises five parts for green tools, such as ultrasonic waves, microwave heating, visible-light photochemistry, organic electrochemistry, and flow chemistry, along with 72 chapters for each bioactive molecule of natural origin. Each chapter explores the natural source, structure, systematic name, structural features, compound class, biological activity, conventional approaches for their chemical synthesis, and demerit(s) of conventional approaches (where applicable). Finally, critical features of total synthesis using modern sustainable techniques, including reaction types, synthetic strategy, and synthetic route utilizing modern sustainable tools for each bioactive natural product and secondary metabolites, are discussed brilliantly. The spectrum of application of total synthesis of bioactive natural products using modern sustainable techniques may promote the development of more eco-friendly synthetic processes so that the next generations can live on this planet with a minimum energy requirement for chemical reactions with the least pollution.

Download or read book New Methods for the Synthesis of Biologically Active Natural Products written by Jeremy Nugent and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of seven scientific articles and is preceded by an overview that contextualises all of this submitted/published work. Publication 1 is a literature review on the chemistry of the palladium-catalysed intramolecular Alder-ene (IMAE) reaction, a powerful method for the construction of carbon-carbon bonds. It focusses only on the cyclisation reactions of hetero-atom linked 1,6-enynes to form cis-fused hexahydro-indoles and -benzofurans. It serves to contextualise some of the author's other published research in the area. Publication 2 consists of an invited book chapter that reviews the Banwell Group's efforts to synthesis the Amaryllidaceae alkaloid galanthamine, as well as analogues thereof, in order to further investigate the biological properties of such compounds. Similarly, Publication 3 reports a seventeen-step reaction sequence that was used to synthesise rac-galanthamine. This route featured an intramolecular Alder-ene cyclisation and a Diels-Alder/aromatisation reaction sequence to install the tricyclic framework of the natural product. Publication 4 describes the first total synthesis of the Illicium-derived sesquineolignan simonsol C, a natural product that is structurally similar to galanthamine. This twelve-step synthesis of simonsol C featured a Mitsunobu reaction and an intramolecular Heck reaction to establish the tetracyclic framework of simonsol C. A second-generation synthesis of rac-galanthamine is reported in Publication 5. This investigation, which used methodology developed in the aforementioned synthesis of simonsol C, involved, as a key step, an intramolecular Heck reaction to install the tricyclic framework of rac-galanthamine. Publication 6 describes investigations concerned with establishing the reactivity profile of N-methoxy-N-methylcyanoformamide and its capacity to introduce the Weinreb amide functionality into organic frameworks. Specifically, it describes the reaction of this cyanoformamide with various enolates and organometallic species. Publication 7 details the synthesis of N-methoxy-N-methylcyanoformamide (a previously unreported compound) via a two-step procedure. The Appendix to the thesis is comprised of a report arising from single-crystal X-ray analysis of a key compound synthesized by the author. This analysis and the derived reports are the result of studies carried out by Dr Brett Schwartz.

Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.
