Enantioselectivity is a concept within chemistry and biochemistry that refers to the ability of a chiral compound or catalyst to selectively react with one enantiomer over the other. Enantiomers are mirror-image isomers of a molecule that are non-superimposable, similar to left and right hands. Enantioselective reactions are important in various fields such as pharmaceuticals, agrochemicals, and materials because the biological activity or properties of a molecule often depend on its stereochemistry. Researchers often study the mechanisms and factors that influence enantioselectivity in order to develop more efficient and selective reactions for the synthesis of chiral compounds. This research area plays a crucial role in drug development, as enantiopure drugs often have better efficacy and reduced side effects compared to racemic mixtures.
