Book Synopsis Progress Toward the Total Synthesis of Batrachotoxinin A and Phorboxazole B by : Amber Reilly
Download or read book Progress Toward the Total Synthesis of Batrachotoxinin A and Phorboxazole B written by Amber Reilly and published by . This book was released on 2010 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I of this dissertation presents the studies directed toward the total synthesis of batrachotoxin. The general approach towards the synthesis of batrachotoxin involves preparation of the AB rings and the DE rings independently, followed by union of these two ring systems, subsequent closure of the C ring, and elaboration to the natural product. A deconjugative alkylation approach has thus far proved to be the most reliable route to the union of the AB rings to the DE rings, however other methods should be explored. Model studies and synthesis of advanced intermediates have provided a good foundation for future work towards the synthesis of batrachotoxin. Part II of this dissertation presents the studies directed toward the total synthesis of Phorboxazole B with an emphasis on efforts for uniting the side chain and macrocyclic core of the natural product by Wittig olefination. Model studies provided detailed insight into the conditions that would be optimal for union of these two advanced intermediates. While these model studies indicated a promising outcome and were even performed on highly elaborate model compounds, these conditions did not translate well in the union of the real side chain and macrocyle of Phorboxazole.

Book Synopsis Total Synthesis of Phorboxazole A by : Tae Hee Lee
Download or read book Total Synthesis of Phorboxazole A written by Tae Hee Lee and published by . This book was released on 2006 with total page 890 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total synthesis of a highly potent cytotoxic marine natural product, phorboxazole A, is described. Both a palladium(II)-mediated and a palladium(II)-catalyzed intramolecular alkoxycarbonylation were used as key steps for the preparation of the two cis-2,6-disubstituted tetrahydropyran rings (C22-C26 and C11-C15) of phorboxazole A. The synthesis used a convergent approach involving five subunits, namely to prepare C3-C8 (195), C9-C19 (149), C20-C32 (131), C33-C41 (130) and C42-C46 (129). Assembly of two subunits, 130 and 131, employed Evans coupling protocol and provided 141 in excellent yield. The coupled product 141 was converted to aldehyde 215 in a six step sequence in which Julia-Kocienski olefination using a benzothiazole sulfone 129 was used to install the triene side chain. Allylsilylation of 149 with 195 afforded 202, which was linked by Wittig olefination with 215 to furnish 216. The C5-C9 trans-2,6-disubstituted tetrahydropyran ring was constructed from 216 in a three step sequence. Further transformations from 219 led to phorboxazole A (1) as an off-white solid.

Book Synopsis The Combinatorial Index by : Barry A. Bunin
Download or read book The Combinatorial Index written by Barry A. Bunin and published by Elsevier. This book was released on 1998-04-15 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the explosion of combinatorial solid-phase methods, access to information has become one of the main barriers facing a synthetic chemist who is contemplating a combinatorial approach to a medicinal chemistry problem. The Combinatorial Index is an answer to that problem. This compendium of methods from the primary literature provides quick and convenient access to reliable synthetic transformations as well as information on linkers and analytical methods. Each synthetic procedure is preceded by a section entitled"Points of Interest,"which highlights the strengths and weaknesses of the various studies. The index also covers the use of solution-based synthesis for the generation of molecular diversity. - Organized for rapid retrieval of published information on classes of synthetic transformations, linkers, and analytical methods - Serves as a laboratory manual for bench chemists - Includes a chapter on linkers to assist in choice of linking strategy - Discusses strengths and limitations of the various methods - Contains a structural index showing functional group transformations in solid-phase synthesis

Book Synopsis Combinatorial Chemistry by : Günther Jung
Download or read book Combinatorial Chemistry written by Günther Jung and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of success goes on and on - with a new book on combinatorial chemistry, edited by Gunther Jung! Combinatorial chemistry is a proven time- and resource-saving synthetic method of outstanding importance for industrial processes. Compound libraries help to save time and money, especially in the search for new drugs, and therefore play a pivotal role in solving the problem of the worldwide increasing demand for new and more active drugs. Not only substances, which are of interest for pharmaceutical chemistry, but also materials, catalysts, and biomolecules such as DNA or oligosaccharides are readily available with high structural diversities. The broad scope of combinatorial sciences is reflected by this book, edited by Gunther Jung: The synthetic methods discussed range from solid-phase to solution-phase synthesis, from preparations of small molecules such as amines or alcohols to those of complex biomolecules. Feasible methods, efficient techniques, new trends in automation, and state-of-the-art fast instrumental analytical and screening methods are presented with many practical tips and tricks for everybody working in combinatorial chemistry. This is the book written by specialists for specialists and for everyone aspiring to become an insider! It is an indispensible source of information for researchers working in organic synthesis, catalysis, biochemistry, and biotechnology, pharmaceutical and clinical chemistry, material sciences, and analytical chemistry.
Book Synopsis Carbohydrate Mimics by : Yves Chapleur
Download or read book Carbohydrate Mimics written by Yves Chapleur and published by Wiley-VCH. This book was released on 1998-09-10 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbohydrate Mimics Concepts and Methods Edited by Yves Chapleur Apart from the various functions of carbohydrates in natural processes they are important building blocks for drugs, especially antibiotics. In addition, carbohydrates are considered as important structures in the immunological recognition process of the antigen-antibody reaction. The modification of the structure and thereby the chemistry of substrates is a common procedure in nature. This naturally occurring process is reflected in the concept of molecular mimicry, which has become a useful approach in drug discovery. The search for carbohydrate analogues that exhibit better binding activity, biological activity, and stability began with the synthesis of azasugars. A lot of structural modifications around the anomeric center of carbohydrates has been achieved over the last decade, and these are summarized in terms of the different chemical and biological aspects of carbohydrate mimics in one part of this book. In addition to the well established fields of C-glycosides, azasugars and carbasugars the other part of the book focusses on outstanding achievements in carbohydrate mimic research. Everybody who is active in carbohydrate research or is interested in moving into this exciting field will benefit from this up-to-date source of informations. The leading experts in this field describe their scientific approaches to real interdisciplinary puzzles. This book should be an inspiration to scientists in organic, medicinal chemistry, biochemistry, and biology.
