This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial peptides, containing alpha- and/or beta-amino acids with bulky substituents, can potentially possess some unusual properties, for example, decreased conformational ability or formation of stable secondary structures. Therefore, the preparation of such unnatural amino acids is of high interest. In this thesis, a route to enantiomerically pure 1-adamantylglycine was developed. The crucial step was the highly stereoselective addition of adamantylmagnesium bromide to the C=N bond of 2,3-O-cyclohexylidene-D-glyceraldehyde N-benzylnitrone effected in the presence of Lewis acid. Finally, 1-adamantylglycine was synthesized in 28 % yield over 6 steps. The routes to 9-aminofluorenylacetic and beta-aminobeta, beta-diphenylpropionic acids were proposed and they consist in the addition of allyl Grignard reagents to imines with various protecting groups, followed by oxidative transformation of the allyl group. Also some procedures for the preparation of 3,3-disubstituted 4-azetidinones, direct precursors of the corresponding beta-branched beta-amino acids, have been investigated.

Book Synopsis Side Reactions in Organic Synthesis by : Florencio Zaragoza Dörwald
Download or read book Side Reactions in Organic Synthesis written by Florencio Zaragoza Dörwald and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure-reactivity relationship of organic compounds. This textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success-rate. A must for every graduate student but also for every chemist in industry and academia. Contents: 1 Organic Synthesis: General Remarks 2 Stereoelectronic Effects and Reactivity 3 The Stability of Organic Compounds 4 Aliphatic Nucleophilic Substitutions: Problematic Electrophiles 5 The Alkylation of Carbanions 6 The Alkylation of Heteroatoms 7 The Acylation of Heteroatoms 8 Palladium-Catalyzed C-C Bond Formation 9 Cyclizations 10 Monofunctionalization of Symmetric Difunctional Substrates

Book Synopsis The Cyclic Peptide Toxins of Amanita and Other Poisonous Mushrooms by : Jonathan Walton
Download or read book The Cyclic Peptide Toxins of Amanita and Other Poisonous Mushrooms written by Jonathan Walton and published by Springer. This book was released on 2018-05-09 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poisonous mushrooms have fascinated scientists and laypersons alike for thousands of years. Almost all mushroom fatalities are due to the genus Amanita, whose poetic common names (death cap, destroying angel) attest to their lethality. In his classic 1986 book, Theodor Wieland covered the state of our knowledge about the chemistry and biochemistry of the toxins of Amanita mushrooms up until that time, with a particular focus on the decades of chemical research by him and the Wieland dynasty (including his father, brother, brother-in-law, and cousin). Wieland’s book is now mainly of historical interest, with its exhaustive overview of the early chemical studies done without benefit of methods taken for granted by modern chemists. This book is a complete top-to-bottom revision of Wieland’s 1986 book. The material covers history, chemistry, and biology with equal thoroughness. It should be of interest to natural products chemists and biologists, professional and amateur mycologists, and toxicologists. The three scientific fields that are most relevant to the book are natural products chemistry, mycology, and fungal molecular genetics. Dr. Walton is an expert in all three. To maximize the broad utility and appeal of the book, care has been taken to define all technical terms specific to a particular discipline, so that, for example, mycologists will be able to understand the relevant chemistry, and chemists will be able to understand the relevant fungal biology.
Book Synopsis Plant-derived Natural Products by : Anne E. Osbourn
Download or read book Plant-derived Natural Products written by Anne E. Osbourn and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants produce a huge array of natural products (secondary metabolites). These compounds have important ecological functions, providing protection against attack by herbivores and microbes and serving as attractants for pollinators and seed-dispersing agents. They may also contribute to competition and invasiveness by suppressing the growth of neighboring plant species (a phenomenon known as allelopathy). Humans exploit natural products as sources of drugs, flavoring agents, fragrances and for a wide range of other applications. Rapid progress has been made in recent years in understanding natural product synthesis, regulation and function and the evolution of metabolic diversity. It is timely to bring this information together with contemporary advances in chemistry, plant biology, ecology, agronomy and human health to provide a comprehensive guide to plant-derived natural products. Plant-derived natural products: synthesis, function and application provides an informative and accessible overview of the different facets of the field, ranging from an introduction to the different classes of natural products through developments in natural product chemistry and biology to ecological interactions and the significance of plant-derived natural products for humans. In the final section of the book a series of chapters on new trends covers metabolic engineering, genome-wide approaches, the metabolic consequences of genetic modification, developments in traditional medicines and nutraceuticals, natural products as leads for drug discovery and novel non-food crops.

This book was released on 1999-09-30 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inflorescence of the monoecious maize plant is unique among the Gramineae in the sharp separation of the male and female structures. The male tassel at the terminus of the plant most often sheds pollen before the visual appearance of the receptive silks of th the female ear at a lateral bud, normally at the 10 leaf [I]. Earlier studies examined the ontogeny of the growing tissues beginning with the embryo in the kernel through to the obvious protuberances of the growing point as the kernel germinates. The differentiated developing soon-to-become tassel and the lateral bulges that develop into the ears on the lateral buds become apparent very early in the germinating kernel [2, 3, 46]. A certain number of cells are destined for tassel and ear development [8]. As the plant develops, there is a phase transition [\3, 16] from the vegetative lateral buds to the reproductive lateral buds. This change in phase has been ascribed to genotypic control as evidenced in the differences among different genotypes in the initiation of the reproductive [I]. The genetic control of tassel and ear initiation has been gleaned from anatomical observations. Lejeune and Bernier [I2] found that maize plants terminate the initiation of additional axillary meristems at the time of tassel initiation. This would indicate that the top-most ear shoot is initiated on the same day as the initiation of tassel development and this event signals the end of the undifferentiated growing point.
