When this selectivity results in the formation of an excess of one enantiomer over the other from an achiral or racemic substrate it is sometimes called asymmetric induction. Any reaction which creates a new stereogenic center may proceed in a stereoselective fashion.

asymmetric film asymmetric membrane asymmetric induction The traditional term describing the preferential formation in a chemical reaction of one enantiomer or diastereoisomer over the other as a result of the influence of a chiral feature present in the substrate, reagent, catalyst or environment.
