enantioseselektiivisiä

Enantioseselektiivinen refers to a chemical reaction that preferentially forms one enantiomer of a chiral product over the other. Enantiomers are stereoisomers that are non-superimposable mirror images of each other. In many biological systems, the interaction of molecules is highly specific, meaning that only one enantiomer will elicit the desired biological effect while the other may be inactive or even harmful. Therefore, the ability to synthesize chiral molecules in an enantiospecific manner is of great importance in fields such as pharmaceuticals, agrochemicals, and fragrance industries.

Enantiospecific reactions are typically achieved through the use of chiral catalysts, chiral auxiliaries, or chiral reagents. These chiral entities can bias the reaction pathway, favoring the formation of one enantiomer. For example, a chiral catalyst might bind to the reactants in a way that only allows for attack from a specific direction, leading to the preferential formation of a particular stereoisomer. Asymmetric synthesis is a broad term encompassing all methods used to achieve enantiospecificity. The enantiomeric excess (ee) is a measure of the purity of the desired enantiomer, indicating the degree to which one enantiomer is favored over the other. Achieving high enantiomeric excess is a key goal in enantiospecific synthesis.
