Available in PDF, EPUB and Kindle. Book excerpt: Organic chemistry's innovative breadth is especially noteworthy in the area of natural products synthesis. Since the early 1970s, this landmark chemical reference has been documenting the newest and most important of these, in a readily understood format, that clearly traces each of their synthetic routes. Volume Eight, the latest in the series, contains a long-awaited look at the synthesis of tri- and tetracyclic diterpenes, along with the synthesis of naturally occurring quinones. Recent interest in the biologically important polysaccharides has led to a detailed consideration of that compound class. Finally, this new volume contains a look at the strategies and methods specific to natural products containing the spiroketal functional group. The Total Synthesis of Natural Products, Volume Eight, continues the meticulous work of the series, providing chemists with an entirely up-to-date and convenient guide to the critical new syntheses essential to organic chemistry's continuing evolution.

This book was released on 2015 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ortho-Quinone Methides (o-QMs) are highly reactive chemical motifs harnessed by nature for a variety of purposes. Their applications in organic synthesis had been very limited until the low-temperature controllable generation of o-QMs developed by our group. To accelerate the synthetic renaissance for this venerable species, we expanded the application of the o-QM Diels-Alder (o-QMDA) reaction in the total synthesis of pterocarpan family and paecilospirone.

Available in PDF, EPUB and Kindle. Book excerpt: The sixth volume of The Total Synthesis of Natural Products continues editor John ApSimon's exploration of one of the most promising areas for the future development of organic chemistry: synthesis. ApSimon has compiled the first definitive reference source of successful synthetic approaches to a wide variety of natural products. This new volume considers the total synthesis of triterpenes, carbohydrates, aromatic steroids, pyrrole pigments and genes first reported during the period from 1972 through 1982 in this series. The Total Synthesis of Natural Products, Volume Six forms an integral part of the invaluable working reference begun in Volumes One through Five, to which chemists may turn for the available data on the total synthesis of complex molecules. Lessons learned from the synthetic challenges presented here by various natural products will serve as a sound base for this continually evolving field.

This book was released on 2015-06-24 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses two fundamental areas in contemporary organic chemistry: synthesis of natural products and catalytic asymmetric synthesis. Firstly, a new methodology, developed by our research group, which allows the asymmetric synthesis of lactones, a structural unit ubiquitous in natural products, was utilised in the synthesis of a number of natural product analogues that showed significant biological activity. Secondly, the development of a catalytic asymmetric synthesis of a key structural motif present in a number of natural products and pharmaceuticals was accomplished. During the course of this work we discovered dual stereo control, which is significant because it allows the configuration of a new stereo centre to be controlled by a simple change of proton source.

Download or read book Total Synthesis of the Xyloketal Natural Products and Alboatrin written by Jeremy David Pettigrew and published by . This book was released on 2006 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: The isolation and structural characterization of seven closely related natural products, the xyloketals, from a mangrove fungus of the Xylaria species have been reported recently by Lin and co-workers. Of these natural products, all of which incorporate identical chiral nonracemic 5,6-bicyclic acetal moieties, xyloketal A has a unique and aesthetically pleasing C3symmetric molecular structure that was elucidated by detailed spectroscopic studies and by X-ray crystallography. Xyloketal A, B, C and D have also been shown to be potent inhibitors of acetylcholine esterase and so represent important lead compounds for the treatment of neurological diseases. In addition, xyloketal A, B and F have been shown to have L-calcium channel blocking activity. Thus, the total synthesis of these natural products, and structural analogues thereof, is of notable significance. Towards these ends, a series of novel synthetic routes to prepare these compounds were developed. The initial route, in which the key synthetic transformation involved an inverse electron demand hetero Diels-Alder reaction between appropriately substituted ortho-quinone methides and dihydrofurans, afforded (+- ), (+)- and ( - )xyloketal D. In addition, demethyl analogues of xyloketal A and D were prepared. However, the application of this synthetic route to prepare the more structurally complex xyloketals was unsuccessful. A second route, utilizing a phenylboronic acid-mediated condensation reaction as the key synthetic transformation, afforded a series of novel Tris-2H-chromenes that represent structural analogues of the natural product xyloketal A. However, due to the instability of a key reaction intermediate, the total synthesis of xyloketal A was not completed by this route. A third route was also investigated that featured a boron trifluoride diethyl etherate-promoted electrophilic aromatic substitution reaction as a key step. This synthetic route was used to complete total syntheses of xyloketal A, B, D, E, F and G. Moreover, demethyl analogues of xyloketal A, B, C, D, E and G were also prepared. The application of the electrophilic aromatic substitution reaction towards the total synthesis of the structurally related and biologically active natural product alboatrin was also investigated. This led to the first asymmetric total synthesis of this natural product as well as a demethyl analogue.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we have investigated direct routes to several biologically important natural products. Chapter 1 describes a concise construction of core skeleton of malibatol A, employing a novel benzofuran formation methodology and a regio- and stereoselective 7-membered ring formation via Lewis acid catalyzed epoxide ring opening as crucial steps. Chapter 2 describes direct approaches to isoflavanquinones utilizing radical addition to quinones. Three main strategies were presented and were compared to generate radicals from the corresponding precursors. Chapter 3 describes a direct entry to erogorgiaene, naturally occurring potent antitubercular agent, featuring a regioselective metal-halogen exchange and a 6-exo-trig radical cyclization as key transformations. Chapter 4 describes synthetic studies towards antitubercular benzoxazole alkaloids. The core tricyclic skeleton of the originally proposed structures of these natural products was synthesized using an intermolecular Diels-Alder reaction as a key step.
