Book Synopsis Novel Approaches to Synthesis of Nitrogen Containing Heterocycles [microform] by : Ghotas Evindar
Download or read book Novel Approaches to Synthesis of Nitrogen Containing Heterocycles [microform] written by Ghotas Evindar and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 2004 with total page 1174 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Chapter one, a modified approach for mercury promoted synthesis of mono-, di- and tri-substituted 5-aminotetrazoles, and 5-oxo-tetrazoles is reported. This mild protocol is applied to one pot synthesis of a number of amino acid tert-butyl ester- and peptide tert-butyl ester-tetrazole conjugates. It allows for incorporation of a tetrazole moiety into peptide structures. Finally, a solid phase synthetic protocol to incorporate tetrazole heterocycles at the N-terminus of a peptide, using HgCl2, DIC, or Mukaiyama's reagents was achieved. Chapter three describes the synthesis of 2-aminobenzimidazoles via intramolecular C-N bond formation between an aryl halide and a guanidine moiety using either copper or palladium catalysis. Inexpensive copper salts, such as CuI, are generally superior to the use of palladium catalysts. Regioselective cyclizations can also be achieved in high yield under CuI/1,10-phenanthroline catalyzed conditions, whereas palladium catalysis results in the formation of regioisomeric products. Copper- and palladium-catalyzed intramolecular C-S bond formation by cross-coupling between an aryl halide and thiourea functionality is also demonstrated for the synthesis of 2-aminobenzothiazoles. The copper-catalyzed reaction further expands the recent studies exploring the utility of copper salts as replacements for palladium in carbon-heteroatom bond forming reactions. This methodology is applied to the synthesis of the histamine H1-receptor antagonist astemizole (Hismanal) and its highly active metabolite norastemizole. This work is the first serious study of metal catalyzed arylation of guanidines, and is one of a handful of examples of copper catalyzed cyclizations involving C-N bond formation. Chapter two describes a modified Edman degradation procedure to provide an effective means of introducing a heterocycle at the N-terminus of an amino acid amide or peptide. Reaction of a peptide with an isothiocyanate, followed by dehydrothiolative trapping of the intermediate thiourea by intramolecular cyclization of the weakly nucleophilic adjacent amide nitrogen, generates an iminohydantoin. Solution-phase parallel synthesis of iminohydantoins and polymer-supported synthesis of dipeptide and tripeptide derived iminohydantoins were also achieved. Chapter four describes the formation of various benzoxazoles and a handful of benzthiazoles via intramolecular C-O cross-coupling between an aryl halide and an amide oxygen/sulfur using a catalytic amount of copper. Investigation of various ligands revealed 1,10-phenanthroline to be a superior ligand in benzoxazole formation. This protocol allowed for aryl, alky, vinyl, and hetero-aromatic substitutions at position 2-oxazole. A number of substitutions on the phenyl ring of benzoxazole were also well tolerated. An intermolecular approach has also been investigated. The developed intramolecular protocol is applied to total synthesis of antitumor agent UK-1 46 and its analog Me-UK-1 47. Also, a new protocol for the formation of substituted aminothiatriazoles from thiocarbamoylimidazolium salts is outlined. Thiocarbamoylimidazolium salts are synthesized from the corresponding amines by treatment with thiocarbonyldiimidazole (TCDI) followed by methylation with iodomethane. Thiocarbamoylimidazolium salts are shown to act as thiocarbamoyl cation equivalents. Substitution of the salts by azide anion followed by electrocyclization affords substituted aminothiatriazoles in good to excellent yields.

Download or read book Heterocyclic Chemistry written by John A. Joule and published by John Wiley & Sons. This book was released on 2013-05-28 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has so closely matched the requirements of its readership over the years that it has become the first choice for chemists worldwide. Heterocyclic chemistry comprises at least half of all organic chemistry research worldwide. In particular, the vast majority of organic work done in the pharmaceutical and agrochemical industries is heterocyclic chemistry. The fifth edition of Heterocyclic Chemistry maintains the principal objective of earlier editions – to teach the fundamentals of heterocyclic reactivity and synthesis in a way that is understandable to second- and third-year undergraduate chemistry students. The inclusion of more advanced and current material also makes the book a valuable reference text for postgraduate taught courses, postgraduate researchers, and chemists at all levels working with heterocyclic compounds in industry. Fully updated and expanded to reflect important 21st century advances, the fifth edition of this classic text includes the following innovations: Extensive use of colour to highlight changes in structure and bonding during reactions Entirely new chapters on organometallic heterocyclic chemistry, heterocyclic natural products, especially in biochemical processes, and heterocycles in medicine New sections focusing on heterocyclic fluorine compounds, isotopically labeled heterocycles, and solid-phase chemistry, microwave heating and flow reactors in the heterocyclic context Essential teaching material in the early chapters is followed by short chapters throughout the text which capture the essence of heterocyclic reactivity in concise resumés suitable as introductions or summaries, for example for examination preparation. Detailed, systematic discussions cover the reactivity and synthesis of all the important heterocyclic systems. Original references and references to reviews are given throughout the text, vital for postgraduate teaching and for research scientists. Problems, divided into straightforward revision exercises, and more challenging questions (with solutions available online), help the reader to understand and apply the principles of heterocyclic reactivity and synthesis.
Book Synopsis Synthesis of Naturally Occurring Nitrogen Heterocycles from Carbohydrates by : El Sayed H. El Ashry
Download or read book Synthesis of Naturally Occurring Nitrogen Heterocycles from Carbohydrates written by El Sayed H. El Ashry and published by Wiley-Blackwell. This book was released on 2008-04-15 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbohydrates are widely distributed in nature and widely available, and so are considered as a promising feedstock for the preparation of many organic chemical compounds. They are particularly useful in the preparation of nitrogen heterocycles because of their related structural characteristics and easy availability. Synthesis of Naturally Occurring Nitrogen Heterocycles from Carbohydrates will review the recent literature dealing with use of carbohydrates as raw materials in the synthesis of these materials. The text contains six chapters arranged according to the complexity of the heterocyclic compounds discussed, ranging from five to seven membered rings and from single to multiple fused rings. The book provides a detailed discussion of the various synthetic approaches to these compounds, using carbohydrate starting materials, and does not merely reference synthetic methodology but attempts to give as much detail as possible on the actual experimental conditions used, in such a way that the chemist can use the information directly to design a multi-step synthesis. It discusses the different approaches to the synthesis of a wide range of naturally occurring nitrogen heterocycles in a format that enables the reader to make comparisons and decisions on whether to use a certain procedure, to modify it, or to devise a new synthetic methodology.

Download or read book Solid-Phase Organic Synthesis written by Patrick H. Toy and published by John Wiley & Sons. This book was released on 2012-01-10 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents both the fundamental concepts and the most recent applications in solid-phase organic synthesis With its emphasis on basic concepts, Solid-Phase Organic Synthesis guides readers through all the steps needed to design and perform successful solid-phase organic syntheses. The authors focus on the fundamentals of heterogeneous supports in the synthesis of organic molecules, explaining the use of a solid material to facilitate organic synthesis. This comprehensive text not only presents the fundamentals, but also reviews the most recent research findings and applications, offering readers everything needed to conduct their own state-of-the-art science experiments. Featuring chapters written by leading researchers in the field, Solid-Phase Organic Synthesis is divided into two parts: Part One, Concepts and Strategies, discusses the linker groups used to attach the synthesis substrate to the solid support, colorimetric tests to identify the presence of functional groups, combinatorial synthesis, and diversity-oriented synthesis. Readers will discover how solid-phase synthesis is currently used to facilitate the discovery of new molecular functionality. The final chapter discusses how using a support can change or increase reaction selectivity. Part Two, Applications, presents examples of the solid-phase synthesis of various classes of organic molecules. Chapters explore general asymmetric synthesis on a support, strategies for heterocyclic synthesis, and synthesis of radioactive organic molecules, dyes, dendrimers, and oligosaccharides. Each chapter ends with a set of conclusions that underscore the key concepts and methods. References in each chapter enable readers to investigate any topic in greater depth. With its presentation of basic concepts as well as recent findings and applications, Solid-Phase Organic Synthesis is the ideal starting point for students and researchers in organic, medicinal, and combinatorial chemistry who want to take full advantage of current solid-phase synthesis techniques.
