Chirality (electromagnetism) — Chirality with hands and two enantiomers of a generic amino acid. The term chiral (pronounced /ˈkaɪrəl/) describes an object, especially a molecule, which has or produces a non superimposeable mirror image of itself. In chemistry, such a … Wikipedia

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
Enantioselective synthesis — Enantioselective synthesis: Sharpless epoxidation Enantioselective synthesis, also called chiral synthesis, asymmetric synthesis or stereoselective synthesis, is organic synthesis that introduces one or more new and desired elements of… … Wikipedia
Enantiomer — This article is about the concept in chemistry. For a discussion of enantiomers in mathematics, see Chirality (mathematics). (S) (+) lactic acid (left) and (R) (–) lactic acid (right) are nonsuperposable mirror images of each other In chemistry,… … Wikipedia
Stereoisomerism — The different types of isomers. Stereochemistry focuses on stereoisomers Stereoisomers are isomeric molecules that have the same molecular formula and sequence of bonded atoms (constitution), but that differ only in the three dimensional… … Wikipedia
Chiral auxiliary — A chiral auxiliary is a chemical compound or unit that is temporarily incorporated into an organic synthesis so that it can be carried out asymmetrically with the selective formation of one of two enantiomers[1][2] . Chiral auxiliaries are… … Wikipedia
Optical rotation — (optical activity) is the turning of the plane of linearly polarized light about the direction of motion as the light travels through certain materials. It occurs in solutions of chiral molecules such as sucrose (sugar), solids with rotated… … Wikipedia
Chiral pool synthesis — is a strategy that aims to improve the efficiency of chiral synthesis. It starts the organic synthesis of a complex enantiopure chemical compound from a stock of readily available enantiopure substances. Common chiral starting materials include… … Wikipedia
Chiral ligand — In chemistry a chiral ligand is a specially adapted ligand used for asymmetric synthesis. This ligand is an enantiopure organic compound which combines with a metal center by chelation to form an asymmetric catalyst. This catalyst engages in a… … Wikipedia
