Download or read book More Dead Ends and Detours written by Miguel A. Sierra and published by John Wiley & Sons. This book was released on 2013-07-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Success comes in many forms and in synthesis it can be a failure that results in their ultimate successful solutions. This long-awaited sequel to "Dead Ends and Detours" retains the proven concept while featuring over 20 new case studies of failed strategies and their (successful) solutions in natural product total synthesis. Additionally, computational models are used to discuss the problem in much more detail and to provide readers with additional information not found in the primary literature. The topics range from classic synthetic reactions (e.g. Diels Alder reaction), metal-mediated coupling reactions, metathesis, and asymmetric catalysis to the importance of protecting and activating groups. This book will benefit not only graduate students in organic chemistry but also advanced researchers as they gain knowledge derived from the step-by-step analysis of mistakes made in the past and, thus be able to improve their own chemical reaction planning. With its coverage of the most commonly applied reaction types, the book perfectly complements its predecessor, which focuses on general aspects, such as reactivity and selectivity.

One of my co-workers confessed that Classics I was the book on his bedside table while he prepared his thesis defense. Isn't that the highest distinction for a monograph? I have every reason to believe that Classics II will equally stand the selection process by students (and probably their supervisors too)." –Angewandte Chemie, 2004 "Well, there is a new pleasant read for the advanced student and even the experienced. It is the second volume to the established Classics in Total Synthesis and it continues the series extremely well." –ChemBioChem, 2004 "...the real innovation of this volume is the inclusion of alternative pathways to the same target molecule by other researchers. This enables the reader to appreciate that there are also other solutions to certain structural problems than those of the original synthesis. ... Let us hope that K. C. Nicolaou and his associates will present us with these future achievements in the same clear, informative and innovative format they have with the previous two volumes." –Applied Organometallic Chemistry

Download or read book Dead Ends and Detours written by Miguel A. Sierra and published by Wiley-VCH. This book was released on 2004-12-27 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: A plethora of publications provide valuable information for the organic chemist, yet the results are almost always based on successful reactions. However, a chemist's life is unfortunately not that easy. On the contrary, trial and error is still one of the most commonly used methods. Thus it would be useful to have access to those syntheses that do not work, since they also provide important results of great importance for further synthesis. This long-awaited book by M. A. Sierra and M. C. de la Torre fills just such a gap. Using major total syntheses they explain the most varied problems and recommend ways out of such dilemmas: Problems at the start and end of a synthesis, difficult and unexpected reactivities of functional groups, problems due to steric properties and much more. The result is a true wealth of information for any organic chemist. The essential tool for successful total synthesis.

Download or read book Studies on the Total Synthesis of Some Biologically Active Natural Products written by Yiwen Zhang and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The body of this thesis is comprised of four scientific journal articles and a patent. It is preceded by an overview that contextualizes all of this submitted/published work. The first major part of this thesis is comprised of Publication 1. This is a review concerned with the chemical syntheses of the cochliomycins, including congener A, and certain related resorcylic acid lactones (RALs). pecifically, Publication 1 reviews the recently published literature on the cochliomycins and related, co-occurring RALs and is accompanied by a brief commentary on the source organisms and certain of their biological properties. It serves to contextualize some of the author's other published research incorporated in the thesis. The second major part of this thesis is comprised of Publication 2. This details work concerned with establishing the true structure of the marine-derived RAL neocosmosin A. Specifically, the structure, A, originally assigned to neocosmosin A was synthesized with the key steps involving olefin-cross metathesis, ring-closing metathesis, palladium- catalyzed Meinwald rearrangement and Mitsunobu esterification reactions. A late-stage and simple modification to the reaction sequence also provided the enantiomer B that, in fact, represents the true structure of the natural product. The third major part of this thesis is comprised of Publication 3. This details the development of modular total syntheses of the marine-derived alkaloids discoipyrroles A and B. Specifically, the intermediates C and D (see below) were prepared from (parent) pyrrole using Ullmann-Goldberg and Suzuki-Miyaura cross-coupling, Vilsmeier-Haack formylation, electrophilic bromination, and Wittig olefination reactions as key steps. A late stage MoOPH-mediated oxidative cyclization reaction was then employed to assemble the novel heterobicyclic core of the target discoipyrroles. The fourth major part of this thesis is comprised of Publication 4. This details the first total synthesis of the most structurally complex member of the small family of marine- derived discoipyrroles, namely congener D. This synthesis, which used methodology developed during the course of the aforementioned syntheses of the discoipyrroles A and B, involved, as key steps, the MoOPH-mediated oxidative cyclization of precursor E and this was followed by conjugate addition and redox processes. The fifth and final part of this thesis is comprised of Publication 5. This patent details inventions related to methods for preparing a variety of discoipyrrole-like compounds and novel analogues, as well as pharmaceutical compositions comprising these compounds and their possible use in therapeutic settings. For example, compound F, which incorporates a discoipyrrole-like core structure, was synthesized in four steps from indole and involving the aforementioned MoOPH-mediated oxidative cyclization as one of the key processes. The Appendices to the thesis are comprised of a series of reports arising from single-crystal X-ray analyses of certain key compounds synthesized by the author. Drs Jas Ward, Paul Carr or Anthony Willis, members of the Research School of Chemistry's Crystallographic Analysis Unit, conducted these analyses.
