Donald J. Cram

Donald James Cram ( born April 22, 1919 in Chester, Windsor County, Vermont, † June 17, 2001 in Palm Desert, California ) was an American chemist and Nobel Chemistry laureate.

Cram studied chemistry at Rollins College, Florida and at the University of Nebraska. After completing his PhD in organic chemistry from Harvard University in 1947, he went to the University of California at Los Angeles, where he became professor in 1956. In 1952 he exhibited at the Cram's rule, the predictions about the course of diastereomeric reactions allowed.

He received in 1987, together with Jean -Marie Lehn and Charles Pedersen received the Nobel Prize in Chemistry for the development and use of molecules with structure-specific interactions of high selectivity ( supramolecular chemistry ). In 1993 he received the National Medal of Science, 1986 Willard Gibbs Medal, the 1992 NAS Award in Chemical Sciences. 1965 American Chemical Society Award for Creative Work in Synthetic Organic Chemistry, 1974 Arthur C. Cope Award, 1989, the Glenn T. Seaborg Medal and 1984 Tolman Award.

He theorized about the catalytic asymmetric induction on (eg the mentioned Cram rule) and examined in the 1950s and cyclophanes from the 1980s resorcinarenes, molecules that can serve as transport capsules.
