Download or read book Efforts Towards the Total Synthesis of Natural Product Alkaloids (+-) Lycorine and Gracilamine, Gold-catalyzed Diene Formation, and Oxy-CcopeeneClaisenDiels-Alder Reactions to Form the Homo-steroid Skeleton written by Anik Michelle Chartrand and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The amaryllidaceae family is an attractive source of alkaloids, which are valuable targets for total synthesis. This thesis describes the ingenious approach to the synthesis of two amaryllidaceae alkoids: (+/-)-lycorine and gracilamine. Utilization of the phenylbutadiene and pyrroline intramolecular push-pull Diels-Alder reaction for lycorine and of the intramolecular 1,3-dipolar cycloaddition for gracilamine is described. A route was developed to give access to advanced intermediates required for both syntheses. However the existing methodology did not fully accommodate the complete core structure of the targets. Development of a new novel gold-catalyzed reaction is also depicted. A facile and quick method to generate dienes from propargylic acetates and pyvaloates has been developed. The scopes and limitations of this methodology are discussed. The application of the newly discovered Au(PPh3)Cl and acid catalyst system was examined. Finally, we investigated the 1-alkynyl-2-vinyl-cyclohexanols for the formation of multi-cyclic skeletons found in natural products. Our goal was to develop a way to easily access the steroid and/or carbocyclic core in one tandem reaction sequence. To this end, the use of a tandem oxy-cope/Claisen/ene/Diels-Alder reaction was developed. The tandem oxy-Cope/Claisen/ene/Diels-Alder reaction can produce up to 9 contiguous stereogenic centers where two are quaternary. In addition, this domino process provides the steroid core possessing much exploitable functionality.

This book was released on 2016-04-30 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book connects a retrosynthetic or disconnection approach with synthetic methods in the preparation of target molecules from simple, achiral ones to complex, chiral structures in the optically pure form. Retrosynthetic considerations and asymmetric syntheses are presented as closely related topics, often in the same chapter, underlining the importance of retrosynthetic consideration of target molecules neglecting stereochemistry and equipping readers to overcome the difficulties they may encounter in the planning and experimental implementation of asymmetric syntheses. This approach prepares students in advanced organic chemistry courses, and in particular young scientists working at academic and industrial laboratories, for independently solving synthetic problems and creating proposals for the synthesis of complex structures.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Each volume reviews the total synthesis of a set of compounds looking at syntheses reported historically and at the practice current at the time of publication. From volume 1 focusing on carbohydrates, prostagladins, nucleic acids, antibiotics, naturally occurring oxygen ring compounds and pyrrole pigments, the series continues with coverage of aromatic steroids, monoterpenes, triterpenes, sesquiterpenes, cannabinoids, natural inophores, insect pheromones and alkaloids. Volumes revisit the total synthesis of key compounds such as carbohydrates, nucleic acids and pyrrole pigments several times during the series building a picture of the historic development of total synthesis techniques for these major groups. Chapters are edited by experts in their field to give a complete overview of the best in the field at the time.

This book was released on 2013-08-16 with total page 1836 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brings together the best tested and proven stereoselective synthetic methods Both the chemical and pharmaceutical industries are increasingly dependent on stereoselective synthetic methods and strategies for the generation of new chiral drugs and natural products that offer specific 3-D structures. With the publication of Stereoselective Synthesis of Drugs and Natural Products, researchers can turn to this comprehensive two-volume work to guide them through all the core methods for the synthesis of chiral drugs and natural products. Stereoselective Synthesis of Drugs and Natural Products features contributions from an international team of synthetic chemists and pharmaceutical and natural product researchers. These authors have reviewed the tremendous body of literature in the field in order to compile a set of reliable, tested, and proven methods alongside step-by-step guidance. This practical resource not only explores synthetic methodology, but also reaction mechanisms and applications in medicinal chemistry and drug discovery. The publication begins with an introductory chapter covering general principles and methodologies, nomenclature, and strategies of stereoselective synthesis. Next, it is divided into three parts: Part One: General Methods and Strategies Part Two: Stereoselective Synthesis by Bond Formation including C-C bond formation C-H bond formation C-O bond formation C-N bond formation Other C-heteroatom formation and other bond formation Part Three: Methods of Analysis and Chiral Separation References in every chapter serve as a gateway to the literature in the field. With this publication as their guide, chemists involved in the stereoselective synthesis of drugs and natural products now have a single, expertly edited source for all the methods they need.

This book was released on 2023-04-25 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Sustainable Techniques in Total Synthesis of Bioactive Natural Products comprises five parts for green tools, such as ultrasonic waves, microwave heating, visible-light photochemistry, organic electrochemistry, and flow chemistry, along with 72 chapters for each bioactive molecule of natural origin. Each chapter explores the natural source, structure, systematic name, structural features, compound class, biological activity, conventional approaches for their chemical synthesis, and demerit(s) of conventional approaches (where applicable). Finally, critical features of total synthesis using modern sustainable techniques, including reaction types, synthetic strategy, and synthetic route utilizing modern sustainable tools for each bioactive natural product and secondary metabolites, are discussed brilliantly. The spectrum of application of total synthesis of bioactive natural products using modern sustainable techniques may promote the development of more eco-friendly synthetic processes so that the next generations can live on this planet with a minimum energy requirement for chemical reactions with the least pollution.
