twostereocenter
Twostereocenter is a term used in stereochemistry to describe a molecule that contains two stereogenic centers, or stereocenters. A stereocenter is an atom at which exchanging two substituents leads to a stereoisomer that is not superimposable on the original structure. Carbon atoms bearing four different substituents are the most common stereocenters, but other elements may also act as stereocenters.
In a twostereocenter system, up to four stereoisomers may exist. These include two enantiomeric pairs that
Another well-known example is tartaric acid, which exists as two enantiomers (D- and L-tartaric acid) and a
Notation and determination: each stereocenter is assigned an absolute configuration, R or S, by the Cahn–Ingold–Prelog
Relevance and methods: twostereocenter systems are central to stereochemistry in organic synthesis, medicinal chemistry, and natural
