asymmetric synthesis |
Also found in: Wikipedia | 0.03 sec. |
asymmetric synthesisChemical reaction by which unequal amounts of two product isomers are formed. It is normally not possible to synthesize from materials that do not have optical activity (i.e., are not chiral) one stereoisomer of a chiral compound without the other, but use of a chiral auxiliary, such as an enzyme or other catalyst, a solvent, or an intermediate, can force the reaction to produce predominantly or only one isomer. Asymmetric syntheses are often called stereoselective; if one product forms exclusively, it is stereospecific. asymmetric synthesis [¦ā·sə¦me·trik ′sin·thə·səs] (organic chemistry) Chemical synthesis of a pure enantiomer, or of an enantiomorphic mixture in which one enantiomer predominates, without the use of resolution.

It could be used to make many kinds of drugs or compounds -- and almost any molecule that involves an asymmetric reaction. This first handbook to focus solely on the application of N-heterocyclic carbenes in synthesis covers metathesis, organocatalysis, oxidation and asymmetric reactions, along with experimental procedures. |
