What was discovered

Small chiral organic molecules (proline, imidazolidinones) catalyse enantioselective reactions without metals, cheaply and in an environmentally friendly way. The third pillar of catalysis alongside metals and enzymes.

Nobel Prize in Chemistry 2021; simultaneous publications in 2000.
