Natural Products de Dieter Sicker

Natural Products

Autor Dieter Sicker, Klaus-Peter Zeller, Hans Ullrich Siehl, Stefan Berger
en Limba Engleză Paperback – 23 ian 2019

Reținem, încă de la primele pagini ale volumului Natural Products – Isolation, Structure Elucidation, History, importanța exercițiilor și a întrebărilor recapitulative care însoțesc fiecare studiu de caz. Această componentă practică transformă lucrarea dintr-o simplă expunere teoretică într-un instrument de lucru interactiv pentru laborator. Găsim în acest manual, semnat de D Sicker și publicat de Wiley Vch, o structură didactică riguroasă aplicată pe 20 de produse naturale de uz cotidian, de la alcaloizi la terpenoide. Fiecare capitol urmează un tipar uniform, esențial pentru un proces de învățare logic: începe cu fundalul istoric al substanței, continuă cu detalierea tehnicilor de izolare și se finalizează cu elucidarea structurii chimice. Notăm cu interes includerea datelor spectrale complete pentru fiecare compus, acoperind spectroscopia UV, IR, RMN și spectrometria de masă. Această abordare integrată permite studenților și cercetătorilor să observe direct corelația dintre teoria chimică și datele experimentale brute. Cititorii familiarizați cu Introduction to Natural Products Chemistry de Rensheng Xu vor aprecia în acest volum accentul pus pe latura aplicativă și pe istoria descoperirilor, spre deosebire de abordarea axată preponderent pe rezultatele cercetării regionale. În timp ce alte lucrări din domeniu, precum Natural Products de James R Hanson, oferă o privire de ansamblu asupra metabolismului secundar, ediția de față se distinge prin „sfaturile practice de laborator” care ghidează utilizatorul pas cu pas în procesul de extracție și caracterizare. Este un suport de curs modern, în format color, care reușește să sintetizeze informația tehnică fără a sacrifica rigoarea științifică necesară în chimia farmaceutică și biochimie.

De ce să citești această carte

Recomandăm această carte studenților și chimiștilor analiști care doresc să stăpânească tehnicile de izolare a produselor naturale. Dincolo de teoria solidă, câștigați un set prețios de exerciții practice și date spectrale complete (RMN, IR, MS) pentru 20 de compuși esențiali. Este resursa ideală pentru a înțelege drumul unei substanțe de la sursa naturală la structura chimică definită.

Descriere

Written by experienced authors, this book presents numerous natural everyday products with a high range of structural diversity. Twenty natural products have been arranged in five sections, describing three alkaloids, five colored compounds, three carbohydrates and glycosides, seven terpenoids, and two aromatic compounds. Adopting a highly didactical approach, each chapter features a uniform structure: Background, in-depth information about isolation processes and structural characterization as well as a Q&A section at the end. Alongside the theoretical information many practical hints for the laboratory work are also included. A comprehensive overview of UV-, IR- and NMR-spectroscopy as well as mass-spectrometry for every exemplified compound is provided and the understanding of these methods is supported by concluding questions and exercises. Educating and entertaining, this full-color textbook turns the learning process into a real pleasure, not only for students in natural products chemistry but also experienced professionals.

Notă biografică

As a boy, Dieter Sicker, born in 1954 in Chemnitz, was intrigued by the phenomena of material transformations in the kitchen. However, later, he decided to become a chemist rather than a cook. He is convinced that the manifold knowledge gained in the isolation of natural products is helpful for any organic chemist. Working as a lecturer and a practical supervisor at the Institute of Organic Chemistry at the University of Leipzig, he was awarded the title apl. professor in 1997. He is fond of presenting experimental shows in which the beauty of chemistry is both shown and explained to the public.

Klaus-Peter Zeller, born in 1944 in Baden-Baden, worked several years as technician before he could realise his dream to study chemistry. In 1972 he received his doctoral degree from the University of Tübingen. After postdoctoral work at the Heriot-Watt University Edinburgh he returned to Tübingen where he became Professor in 1983. His research and teaching interests focus on reaction mechanisms, photochemistry, mass spectrometry, and more recently science history.

In 1968 Hans-Ullrich Siehl started chemistry studies at the University of Tübingen during, the peak years of student movement and protest. The
structural formula of Astaxanthin was the required answer to the 1973 organic chemistry diploma question, why the color of the lobster change to red on cooking. After his PhD thesis on vinyl cations with Prof. M. Hanack at the University of Saarbrücken he enjoyed eating lobster at weekends in Maine during his postdoctoral work on Isotope eff ects with Prof. M. Saunders at Yale University, Connecticut, 1979. After his Habilitation on NMR spectroscopy of reactive carbocations in Tübingen in 1987 he enjoyed Japanese dishes during a one-year JSPS guest professorship at Kyushu University, Japan. At Ulm University since 1995 his main interests in experimental physical organic chemistry and NMR spectroscopy were successively expanded and complemented by quantum chemical methods such as computational NMR spectroscopy.

Stefan Berger was intrigued by NMR after having won a bottle of beer during an introductory course in organic NMR led by Prof. H. Suhr at the University of Tübingen in 1968. After completing a PhD thesis with Prof. Anton Rieker, in 1973 he joined Prof. J. D. Roberts at Caltech for postdoctoral work, where he also met Prof. D.M. Grant and Prof. D. Seebach, who were then guest professors in Pasadena. This period was decisive to try a Habilitation in NMR spectroscopy, which was achieved at the University Marburg. At the University Leipzig his aim is to combine methodological development of NMR and its application to bioorganic problems.
