Chiral catalysts are important because they enable the production of enantiomerically pure compounds, which are crucial in many applications. For instance, in the pharmaceutical industry, the biological activity of a drug can be highly dependent on its chirality. One enantiomer might be therapeutically active, while the other could be inactive or even harmful. Thus, the ability to produce a single enantiomer using chiral catalysts can improve the efficacy and safety of drugs.
