Asymmetric catalysis typically involves the use of a chiral catalyst that interacts differently with the two enantiomers of the substrate. This differential interaction leads to the preferential formation of one enantiomer. Chiral catalysts can be either metal complexes with chiral ligands, organocatalysts, or even enzymes. The design of these catalysts is crucial, as they must be able to induce chirality while also being efficient and selective.
