Stereocenter — A stereocenter or stereogenic center is an atom, bearing groups such that an interchanging of any two groups leads to a stereoisomer.[1] A chirality center is a stereocenter consisting of an atom holding a set of ligands (atoms or groups of… … Wikipedia
Asymmetric induction — (also enantioinduction) in stereochemistry describes 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,… … Wikipedia
Topicity — Main article: stereochemistry In chemistry, topicity is the stereochemical relationship of substituents relative to the structure to which they are attached. Depending on the relationship, such groups can be heterotopic, homotopic, enantiotopic,… … Wikipedia
