Cram, Donald James. (1919-2001). Awarded the Nobel Prize for chemistry, together with Lehn, in 1987 for work in elucidating mechanisms of molecular recognition, which are fundamental to enzymic catalysis, regulation, and transport. Cram also studied three-dimensional cyclic compounds that maintained a rigid structure, accepting substrates in a structurally preorganized cavity. He called these compounds cavitands, while Lehn named them cryptands. Cram was awarded a doctorate by Harvard University in 1947. [Pg.343]

Cram, Donald James (1919-2001) American chemist who in 1972 described the synthesis of left- and right-hand (chiral) structural forms of the molecules of certain cyclic polyethers (crown ethers) and achieved a method of the separation of left-and right-handed forms (enantiomers) so as to produce enantiometrically pure samples. This is important because enantiomers may have different biological properties. For this... [Pg.142]
