Book Synopsis Studies on the Intramolecular Diels-Alder Reaction by : Geoff T. Halvorsen

Available in PDF, EPUB and Kindle. Book excerpt: The intramolecular Diels-Alder reaction is widely recognized as a powerful and versatile method for the assembly of complex bicyclic structures in synthetic organic chemistry and has been utilized as a key step in the total syntheses of a number of interesting biologically active natural products. We have studied the use of siloxacyclopentene constrained trienes as a method to control diastereofacial selectivity in the intramolecular Diels-Alder reaction. The siloxacyclopentene constraints could be formed under mild conditions and attached to either the diene or dienophile units of a variety of trienes. These constrained trienes underwent intramolecular Diels-Alder reactions to give cycloadducts with the oxygen contained in the siloxacyclopentene exclusively in an anti-configuration relative to the ring fusion proton. Suitably chosen dienophile activating groups and optimized conditions for cyclization allowed for high levels of selectivity for either cis - or trans -fused cycloadducts in the case of siloxacyclopentenes contained within the diene, while siloxacyclopentenes constraints attached at the dienophile gave exclusively the trans-fused cycloadducts. A siloxacyclopentene constrained tetraene was then utilized in a concise, stereoselective synthesis of the decahydrofluorene core common to the hirsutellones. Synthetic efforts targeting the completion of the hirsutellones via a common biosynthetic intermediate were pursued utilizing a macrobenzannulation strategy. This strategy was abandoned due to inability to prepare a suitable benzannulation precursor. Later a strategy of first forming a five membered ring containing analogue was also pursued, but failed due to an inability to convert a suitable ester to the corresponding furan or thiophene.
Book Synopsis Cycloaddition Reactions in Organic Synthesis by : W. Carruthers
Download or read book Cycloaddition Reactions in Organic Synthesis written by W. Carruthers and published by Elsevier. This book was released on 2013-10-22 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demonstrates the wide scope of cycloaddition reactions, including the Diels-Alder reaction, the ene reaction, 1,3-dipolar cycloadditions and [2+2] cycloadditions in organic synthesis. The author, a leading exponent of the subject, illustrates the ways in which they can be employed in the synthesis of a wide range of carbocyclic and heterocyclic compounds, including a variety of natural products of various types. Special attention is given to intramolecular reactions, which often provide a rapid and efficient route to polycyclic compounds, and to the stereochemistry of the reactions, including recent and developing work on enantioselective synthesis.
Book Synopsis Retrosynthetic Analysis and Synthesis of Natural Products 1 by : Olivier Piva
Download or read book Retrosynthetic Analysis and Synthesis of Natural Products 1 written by Olivier Piva and published by John Wiley & Sons. This book was released on 2019-09-19 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: For chemists, attempting to mimic nature by synthesizing complex natural products from raw material is a challenge that is fraught with pitfalls. To tackle this unique but potentially rewarding task, researchers can rely on well-established reactions and methods of practice, or apply their own synthesis methods to verify their potential. Whatever the goal and its complexity, there are multiple ways of achieving it. We must now establish a strategic and effective plan that requires the minimum number of steps, but lends itself to widespread use. This book is structured around the study of a dozen target products (butyrolactone, macrolide, indole compound, cyclobutanic terpene, spiro- and polycyclic derivatives, etc.). For each product, the different disconnections are presented and the associated syntheses are analyzed step by step. The key reactions are described explicitly, followed by diagrams showing the range of impact of certain transformations. This set of data alone is conducive to understanding syntheses and indulging in this difficult, but worthwhile activity.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the author describes the total synthesis of natural product Maoecrystal V in detail. In the first part of the thesis, the author introduces the research background and reviews the research progress in total synthesis of Maoecrystal V. In the second part, the author develops a novel and concise approach for the stereo selective construction of the tetracyclic model system of Maoecrystal V. The model system is accomplished in 8 steps with 20% yield. In the third part, the author describes the first successful total synthesis of Maoecrystal V and investigates four strategies for constructing the key tetrahydrofuran oxa-bridge skeleton. The total synthesis starts from a known compound and is accomplished in 17 steps with 1.2% yield. The successful total synthesis of Maoecrystal V will contribute to the development of efficient synthetic strategies for natural products and other compounds with complex structures.

Book Synopsis General and Synthetic Methods by : G Pattenden
Download or read book General and Synthetic Methods written by G Pattenden and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.
