Book excerpt: Indole alkaloids constitute an important class of natural products which include a large number of pharmacologically important substances such as the anti-tumour alkaloids, vinblastine and vincristine, the blood pressure lowering substance reserpine, the hallucinatory lysergic acid and its derivatives, and the cardio-arrhythmic alkaloid, ajmalicine. This important field has attracted the leading synthetic organic chemists of the present century to develop synthetic approaches to the challenging structural architecture encountered in many indole alkaloids. The book describes the syntheses of various types of indole alkaloids.

This book was released on 2016 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract A Unified Approach Toward the Total Syntheses of Prenylated Indole Alkaloid Natural Products by Eduardo Valentin Mercado-Marin Doctor of Philosophy in Chemistry University of California, Berkeley Professor Richmond Sarpong, Chair This dissertation describes our approach toward a unifying synthesis of prenylated indole alkaloid natural products. Chapter 1 is an introduction and provides background to this class of natural products, focusing primarily on the isolation, biological activity, biosynthetic, and previous synthetic work of these natural products. This section also includes a discussion of synthetic approaches to the common bicyclo[2.2.2]diazaoctane core embodied in many of these natural products, which sets the stage for our entry into these molecules by a unifying route. Chapter 2 describes our entry into this class of natural products focused primarily on our synthetic and biosynthetic work toward natural products lacking the bicyclo[2.2.2]diazaoctane core. In particular, we discuss the first chemical syntheses of the prenylated indole alkaloids citrinalin B and cyclopiamine B. Along with unambiguously establishing the structures of these natural products, in collaboration with the Berlinck group, we provide evidence for the existence of a common bicyclo[2.2.2]diazaoctane containing precursor as an intermediate to natural products that lack this structural feature. Lastly, Chapter 3 describes our unified strategy for the synthesis of prenylated indole alkaloid natural products, capitalizing on our results described in Chapter 2. This unifying strategy has resulted in the syntheses of stephacidin A and 17-hydroxy-citrinalin B. Key to the success of this approach in accessing congeners containing and lacking the bicyclo[2.2.2]diazaoctane core was a complexity building isocyanate capture to forge the bicyclo[2.2.2]diazaoctane core from a common all fused precursor.

This book was released on 2014 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter one discusses the previous use of synthetic chemistry in biosynthetic studies of natural products. Emphasis is given to more recent work concerning the brevianamide, notoamide, and communesin fungal indole alkaloids. Chapters two and three highlight our explorations of the interrupted Fischer indolization reaction to access indoline containing natural products. Specifically, chapter two focuses on the use of the interrupted Fischer indolization reaction to prepare the Alzheimer's therapeutic candidate, (+)-phenserine (a.k.a. Posiphen), in enantioenriched form. Chapter three is a discussion of our studies to use the interrupted Fischer indolization reaction towards syntheses of the communesin alkaloids and perophoramidine. Chapters four, five, and six present our use of chemical synthesis in the discussion of elucidating the biosynthetic pathways of natural products. In particular, chapter four focuses on the echinocandin lipopeptides and our efforts to identify and characterize the biochemical pathway utilized by nature. Chapters five and six highlight our work to determine the biosynthesis of the chaetoviridin polyketides. In addition, a strategy for introducing structural diversity into polyketides is reported.

Download or read book Indoles written by Richard J. Sundberg and published by Elsevier. This book was released on 1996-05-28 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indoles continue to be of great interest to the pharmaceutical industry and at the current time several thousand specific new derivatives are reported annually. Research has been driven by the wide range of indole derivatives which occur in nature and through the biological activity of many indole derivatives, of both natural and synthetic origin.This book provides a systematic guide to the most useful and important reactions in the field for both synthesis and synthetic modification of the indole ring. While including the most recently developed and promising methods, it also updates informationavailable on classical methods to give the reader an up-to-date and comprehensive view of the subject. The methods are illustrated by procedures drawn from the literature and by tables including examples chosen to indicate both the scope of applicabilityand variations in methodology. The organization of the book is based on the retrosynthetic concept of identifying the bond(s) formed in the reaction, which in turn identifies potential starting materials. - Includes systematic summaries of the most important methods for the construction of indoles from aromatic precursors - Discusses methods for preparing indoles by annelation of pyrroles - Covers methods for adding or modifying substituent groups, including methods for introducing the tryptamine and tryptophan side-chainsExamines reduction/oxidation reactions that are specific for indoles - Considers use of cycloaddition reactions for synthetic elaboration of indoles
