There are still a number of difficulties in chiral chemistry, especially with regard to stereoselective synthesis, despite tremendous progress in the field. It can be challenging to achieve high levels of enantioselectivity, and careful catalyst design and reaction condition optimisation are frequently needed to control the stereochemistry of reactions.

When a molecule is chiral, it means that it lacks symmetry and cannot be superimposed on its mirror counterpart. The existence of a chiral centre, sometimes referred to as a stereocenter, which is usually a carbon atom bound to four distinct substituents, is what causes this asymmetry. Enantiomers are the two non-superimposable mirror-image forms of chiral compounds.
The asymmetric nature of chiral substances results in their distinct physical and chemical properties. Optical activity—the capacity of chiral molecules to rotate the plane of polarised light—is one of their most important characteristics. Enantiomeric purity is important in medication design and development because enantiomers of chiral substances have the same physical properties but different biological and pharmacological actions.

Many biological compounds display chirality, demonstrating the widespread occurrence of chirality in nature. Examples include DNA, carbohydrates, and amino acids, all of which are necessary components of biological systems. In pharmacology, where a drug’s stereochemistry frequently determines its action and toxicity, chirality is very important.

The existence of chiral centres has significant consequences for several scientific fields, especially asymmetric synthesis, materials research, and drug development. Pharmaceuticals, where the unique biological actions of enantiomers need exact control over chirality, heavily relies on enantiopure substances produced from chiral centres. Chiral centres affect the features of polymers, crystals, and nanomaterials in materials science, providing opportunities to modify material properties according to molecular symmetry.
