Abstract: Meso and dl diastereomers of compounds containing two constitutionally equivalent chiral units can be distinguished by using NMR spectroscopy to demonstrate the creation of pseudoasymmetry. In suitable compounds, a new configurational unit, a unit of pseudoasymmetry, can be constructed in ...

Enantioselective synthesis
Enantioselective synthesis, also called chiral synthesis or asymmetric synthesis, is defined by IUPAC as: a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereoisomeric) products in unequal amounts.Put more simply: it is the synthesis of a compound by a method that favors the formation of a specific enantiomer or diastereomer.Enantioselective synthesis is a key process in modern chemistry and is particularly important in the field of pharmaceuticals, as the different enantiomers or diastereomers of a molecule often have different biological activity.
