Available in PDF, EPUB and Kindle. Book excerpt: Carbon-carbon bond forming reactions are arguably the most important processes in chemistry, as they represent key steps in the building of complex molecules from simple precursors. Among these reactions, metal-catalyzed cross-coupling reactions are extensively employed in a wide range of areas of preparative organic chemistry, ranging from the synthesis of complex natural products, to supramolecular chemistry, and materials science. In this work, a dozen internationally renowned experts and leaders in the field bring the reader up to date by documenting and critically analyzing current developments and uses of metal-catalyzed cross-coupling reactions. A particularly attractive and useful feature, that enhances the practical value of this monograph, is the inclusion of key synthetic protocols, in experimental format, chosen for broad utility and application. This practice-oriented book can offer the practitioner short cuts to ensure they remain up-to-date with the latest developments.

Abstract: Abstract of thesis entitled TRANSITION METAL CATALYZED CYCLIZATION AND SYNTHESIS OF TRIPTOLIDE ANALOGS Submitted by Pan Jiehui for the Degree of Doctor of Philosophy at The University of Hong Kong in March 2006 (-)-Triptonide, (-)-triptolide, and 16-hydroxytriptolide are bioactive natural product, isolated from the Chinese medicinal plant Tripterygium wilfordii Hook. F. (Lei Gong Teng). They show potent immunosuppressive, antileukemic, and antifertile activities. However, their mechanisms of actions still remain elusive, and only limited structure-activity relationship studies of triptolide and its analogs have been carried out. I have successfully synthesized bioactive alkyne-derived triptolide probe and azide functionalized fluorophore tags, which were designed for identifying the receptors of triptolide by using the click chemistry method. A model reaction simulating the cycloaddition between the bioactive triptolide probe and rhodamine tag has been successfully accomplished, which could be applied in the search for the receptors of triptolide. Synthetic studies of triptolide analogs could provide new methods to prepare analogs containing moieties different from the original triptolide molecule, and possibly enable its curative effects to be distinguished from its toxic effects. Two efficient cross-coupling methods including the Heck reaction and the Sonogashira coupling have been utilized for the introduction of the C-13 side chain of triptolide analogs. These protocols provide new ways to modify the triptolide molecule at the C-13 position in addition to the Claisen rearrangement. Several novel dimeric triptolide analogs with different functionalities at the C-13 position have been prepared. The exploration of transition metal-catalyzed cyclization reactions has been at the frontier of organic synthesis. I have prepared several sterically bulky N, N'-disubstituted cyclic thiourea-gold(I) complexes. The crystal structures of the complexes reveal the different coordination nature of sulphur in these complexes in the solid state. In solution, a ligand scrambling reaction has been observed with the N, N'-dialkyl cyclic thiourea ligands. Useful information about the equilibrium of ligand scrambling reaction has been obtained from the H NMR experiments. I have used bulky N, N'-disubstituted cyclic thioureas as effective ligands for the Au(I)-catalyzed carbocyclization of 1,3-dicarbonyl compounds with alkynes. The reactions can be readily conducted with a low catalyst loading, short reaction time in an "open flask" system and in high yields. In addition, I have demonstrated an application of the bulky N, N'-disubstituted cyclic thiourea-Au(I) complexes in the cycloisomerization of acetylenic 1,3-dicarbonyl compounds to form γ-lactones and γ-lactams. These reactions can be readily conducted with low catalytic loading in an "open flask" system and provide a new method to generate γ-lactones and γ-lactams.

Book Synopsis Organic Synthesis Using Transition Metals by : Roderick Bates
Download or read book Organic Synthesis Using Transition Metals written by Roderick Bates and published by John Wiley & Sons. This book was released on 2012-04-30 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metals open up new opportunities for synthesis, because their means of bonding and their reaction mechanisms differ from those of the elements of the s and p blocks. In the last two decades the subject has mushroomed - established reactions are seeing both technical improvements and increasing numbers of applications, and new reactions are being developed. The practicality of the subject is demonstrated by the large number of publications coming from the process development laboratories of pharmaceutical companies, and its importance is underlined by the fact that three Nobel prizes have been awarded for discoveries in this field in the 21st Century already. Organic Synthesis Using Transition Metals, 2nd Edition considers the ways in which transition metals, as catalysts and reagents, can be used in organic synthesis, both for pharmaceutical compounds and for natural products. It concentrates on the bond-forming reactions that set transition metal chemistry apart from "classical" organic chemistry. Each chapter is extensively referenced and provides a convenient point of entry to the research literature. Topics covered include: introduction to transition metals in organic synthesis coupling reactions C-H activation carbonylative coupling reactions alkene and alkyne insertion reactions electrophilic alkene and alkyne complexes reactions of alkyne complexes carbene complexes h3- or p-allyl -allyl complexes diene, dienyl and arene complexes cycloaddition and cycloisomerisation reactions For this second edition the text has been extensively revised and expanded to reflect the significant improvements and advances in the field since the first edition, as well as the large number of new transition metal-catalysed processes that have come to prominence in the last 10 years – for example the extraordinary progress in coupling reactions using “designer” ligands, catalysis using gold complexes, new opportunities arising from metathesis chemistry, and C-H activation – without neglecting the well established chemistry of metals such as palladium. Organic Synthesis Using Transition Metals, 2nd Edition will find a place on the bookshelves of advanced undergraduates and postgraduates working in organic synthesis, catalysis, medicinal chemistry and drug discovery. It is also useful for practising researchers who want to refresh and enhance their knowledge of the field.
