Donald James Cram (April 22, 1919June 17, 2001) was an American chemist who shared the 1987 Nobel Prize in Chemistry for “synthesizing three-dimensional molecules that could mimic the functioning of natural molecules.” He also won the National Academy of Science Award in the Chemical Sciences.

Field of Study

Cram expanded upon Charles Pedersen's ground-breaking synthesis of crown ethers, basically two-dimensional organic compounds that are able to recognize and selectively combine with the ions of certain metal elements. Cram synthesized molecules that took this chemistry into three dimensions, creating an array of differently shaped molecules that could interact selectively with other chemicals because of their complementary three-dimensional structures. His work represented a large step toward the synthesis of functional laboratory-made mimics of enzymes and other natural molecules whose special chemical behavior is due to their characteristic structure. Charles J. Pedersen (October 3, 1904–October 26, 1989) was an American organic chemist best known for describing methods of synthesizing cyclic polyethers. ... Crown ethers are heterocyclic chemical compounds that, in their simplest form, are cyclic oligomers of dioxane. ...
