Gerhard Quinkert

from Wikipedia, the free encyclopedia

Gerhard Quinkert (born February 7, 1927 in Lüdenscheid ; † May 6, 2015 ) was a German chemist .

Life and research

Quinkert studied chemistry at the Technical University of Braunschweig and was awarded a doctorate by Hans Herloff Inhoffen in 1955. rer. nat. PhD . In 1961, he also qualified as a professor in Inhoffen's work group. In 1963 he became an associate professor and in 1967 a full professor at the chair for organic chemistry at the TU Braunschweig. Quinkert then moved in 1970 as a professor at the Institute for Organic Chemistry and Chemical Biology at the University of Frankfurt am Main . From 1973 he was a board member of the Society of German Chemists (until 1981) and in 1986 was co-editor of the journals for organic chemistry Tetrahedron and Tetrahedron Letters (until 1998). In addition, he was accepted into the German Academy of Sciences Leopoldina in 1988 and into the Academia Europaea in 1989 . He retired in 1995.

Quinkert's earlier research areas include light-induced reactions of ketones, for example the photolysis of cyclobutanones or the formation of dienyl ketenes from cyclohexadienone derivatives. He also dealt with stereoselective syntheses of steroid lactams , which were achieved by so-called photolactamization .

Another concern of his later years was to bring organic chemistry closer to biology, both in terms of interdisciplinary teaching and research and synthesis methodology oriented towards biological problems.

Honors

Quinkert was awarded a scholarship from the Karl Winnacker Foundation of Hoechst AG in 1961. He received several important science prizes, such as the Emil Fischer Medal (1984), the Adolf Windaus Medal of the University of Göttingen (1985) and the Hans Herloff Inhoffen Medal of the Society for Biotechnological Research in Braunschweig (1994).

In 1996, together with Christian Griesinger and Ernst Egert, he received the Literature Prize of the Fonds der Chemischen Industrie for their book Aspects of Organic Chemistry .
