Download or read book Total Synthesis of Bioactive Natural Products by Palladium Catalyzed Domino Cyclization of Allenes and Related Compounds written by Shinsuke Inuki and published by Springer Science & Business Media. This book was released on 2011-11-23 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author has developed novel methodologies for highly efficient construction of functionalized heterocycles by palladium-catalyzed domino/cascade cyclization of allenes and related compounds containing appropriate nucleophilic group(s). Based on these methodologies, enantioselective total syntheses of bioactive natural products, pachastrissamine (26% overall yield in seven steps), lysergic acid (4.0% overall yield in fifteen steps), lysergol (3.6% overall yield in fifteen steps) and isolysergol (8.2% overall yield in eleven steps) have been achieved. These are more facile synthetic route than those previously reported. These findings would contribute to the development of efficient synthetic methods for biologically active compounds containing a complex structure.

This book was released on 1999-06-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indispensable reference for the twenty-first century chemist... A fascinating and comprehensive look into one of chemistry's fastest growing specialties--sesquiterpene synthesis--Volume Ten of The Total Synthesis of Natural Products focuses on acyclic and monocyclic compounds and sheds light on the structure and makeup of this important class of hydrocarbons. A useful and practical tool for researchers interested in locating any of the major classes of sesquiterpene compounds, the author will also provide, if needed, a database to the more than 1,600 articles on sesquiterpene synthesis. The ultimate index to the newest experimental work in synthetic chemistry, this latest volume in The Total Synthesis of Natural Products series is also a glossary to the new language of chemistry in the next century. Look for the following related title in the series: THE TOTAL SYNTHESIS OF NATURAL PRODUCTS, Volume Eleven Volume Eleven continues the authoritative coverage on sesquiterpene synthesis begun in Volume Ten, examining compounds with bicyclic and tricyclic ring structures., 1997 (0-471-18874-3) The research on the synthesis of sesquiterpenes, derivatives of terpenes, a class of hydrocarbons commonly found in oils, resins, and balsams, has grown exponentially over the past fifteen years. With over 500 sesquiterpene syntheses already developed, the literature on this experimental specialty is voluminous, now encompassing over 1,600 re-search papers. Volume Ten in The Total Synthesis of Natural Products provides a systematic and comprehensive look at acyclic and monocyclic compounds in sesquiterpene synthesis. Reflecting one of the significant changes in sesquiterpene re-search, that is, the increase in compound targets prepared in an optically active form, the present volume includes their absolute configurations, signs of optical rotation, or both. This newest volume in The Total Synthesis of Natural Products series is an "A-to-Z" look at acyclic and monocyclic compounds in sesquiterpene synthesis, one of the most dynamic areas in the ongoing revolution in chemical synthesis, and is a must for the chemical professional.
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.
