John C. Sheehan
John Clark Sheehan (born September 23, 1915 - March 21, 1992 ) was an American chemist and professor of organic chemistry at the Massachusetts Institute of Technology (MIT).
life and work
Sheehan's scientific work mainly deals with the synthesis of penicillin , as well as the synthesis of peptides , other antibiotics , alkaloids and steroids . His work at MIT led to the first total synthesis of the drug. He also synthesized intermediate compounds such as 6-aminopenicillanic acid, which became the basis for various types of synthetic penicillins. In 40 years, Sheehan patented over 30 compounds, including ampicillin , a semi-synthetic penicillin for oral use. Among the members of his working group was the later Nobel Prize winner E. J. Corey .
The American Chemical Society (ACS) honored Sheehan with its ACS Award in Pure Chemistry in 1951 and with its ACS Award for Creative Work in Synthetic Organic Chemistry in 1959 . In 1951 he was elected to the American Academy of Arts and Sciences , in 1957 to the National Academy of Sciences .
