Chiral catalysts are substances that speed up chemical reactions while promoting the formation of chiral molecules, which are compounds that have non-superimposable mirror images. These catalysts are essential in the production of pharmaceuticals and other chemicals, as many biologically active molecules are chiral and their specific orientation can significantly affect their function. The use of chiral catalysts allows for more efficient and selective synthesis of these molecules, reducing the need for multiple reaction steps and minimizing waste. Common types of chiral catalysts include transition metal complexes and organocatalysts, which can be designed to enhance specific reaction pathways, leading to desired chiral products.
