Download or read book Total Synthesis of Natural Products with Antimicrobial Activity written by Andrew Giltrap and published by Springer. This book was released on 2018-05-02 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the development of efficient and scalable total syntheses of natural products that can be used as preferred scaffolds for anti-infective drug discovery. It describes the total synthesis of two classes of antimicrobial non-ribosomal peptides (NRPs) – teixobactin and the skyllamycins – with subsequent biological evaluation. The first part describes the first total synthesis of teixobactin by means of a solid-phase peptide synthesis-macrolactamisation approach, yielding a synthetic natural product that can combat a number of clinically relevant Gram-positive bacterial pathogens. The second part describes the first total synthesis of skyllamycins A-C, a family of structurally complex cyclic NRPs, which inhibit the growth of the Pseudomonas aeruginosa biofilms that are responsible for significant mortality among cystic fibrosis patients.
Download or read book Studies Toward a Total Synthesis of Lactonamycin written by Lewis Preece and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Work was undertaken towards the synthesis of the promising antibiotic lactonamycin (iii). Following the work of Parsons et al. it was proposed that cyclisation of the ene-diyne (i) would give access to advanced pentacyclic intermediate (ii) and that from this a total synthesis of lactonamycin would be achieved (scheme I). Scheme I : Proposed Parsons, Board, Waters cyclisation to form the pentacycle (iii)(For image refer to pdf). A synthesis towards the cyclisation precursor (i) was carried out and a route to the key tetrasubstituted phthalide (v) established. Further chemistry was proposed to complete the synthesis of lactonamycin (scheme II). Scheme II : Formation of a fully substituted benzolactone.(For image refer to pdf). During attempts to introduce the [beta]-bromoallyl group of key intermediate (v) using a high temperature Claisen rearrangement it was established that the benzodioxin (vii) underwent thermolysis to generate the reactive quinone methide intermediate (viii) and that in the presence of a nucleophilic solvent the adduct (ix) was formed (scheme III). Model studies showed the reaction to be both general and high-yielding. Scheme III : Novel quinone methide methodology. (For image refer to pdf).

Available in PDF, EPUB and Kindle. Book excerpt: An outstanding international scientific event in the field of metathesis chemistry, the NATO ASI "Green Metathesis Chemistry: Great Challenges in Synthesis, Catalysis and Nanotechnology" has been recently organized in Bucharest, Romania (July 21- August 2, 2008). Numerous renowned scientists, young researchers and students, convened for two weeks to present and debate on the newest trends in alkene metathesis and identify future perspectives in this fascinating area of organic, organometallic, catalysis and polymer chemistry with foreseen important applications in materials science and technology. Following the fruitful practice of NATO Advanced Study Institutes, selected contributions covering plenary lectures, short communications and posters have been compiled in this special volume dedicated to this successful convention on green metathesis chemistry. General interest was primarily focused on relevant "green chemistry" features related to all types of metathesis reactions (RCM, CM, enyne metathesis, ADMET and ROMP). Diverse opportunities for green and sustainable technologies and industrial procedures based on metahesis have been identified. Largely exemplified was the utility of this broadly applicable strategy in organic synthesis, for accessing natural products and pharmaceuticals, and also its ability to fit in the manufacture of smart and nanostructured materials, self-assemblies with nanoscale morphologies, macromolecular engineering.
Download or read book Studies Towards the Synthesis of Ebelactone A And Maurenone written by Ravindar Kontham and published by LAP Lambert Academic Publishing. This book was released on 2012-03 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph features the studies directed towards the total synthesis of architecturally and biologically interesting polypropionate natural products (-)-Ebelactone-A and (-)-Maurenone utilizing desymmetrization as a key strategy. ( )-Ebelactone A, show structural characteristics in common with macrolide antibiotics. Ebelactones act as potent inhibitors of esterase s, lipases and N-formylmethionine amino peptidases, and they have shown to produce enhance immune responses. They are also reported to inhibit cutinases produced by fungal pathogens. Novel biological activity combined with unique and challenging structure of Ebelactone, made this compound an exciting target for the total synthesis. Secondly, this book described an efficient synthetic protocol for polypropionate natural product (-)-Maurenone, which was isolated by Faulkner et al. in 1986 from specimens of the pulmonate mollusc Siphonaria maura. This monograph is unique in dealing with many interesting synthetic protocols including full experimental procedures, analytical data for all synthetic materials and complete reference sections. This monograph can be served as a good hand book for synthetic organic chemists.
