pseudoenantiomer

A pseudoenantiomer is a type of compound that exhibits chirality but has a nucleus that contains no asymmetric carbon atoms, i.e., carbon atoms with four different substituents. This characteristic is in contrast to true enantiomers, which are pairs of compounds that are related as mirror images of each other but have no identical properties. Unlike enantiomers, pseudoenantiomers are typically achiral¡ in their NMR spectra and do not exhibit optical activity.

In a chiral molecule, the presence of a stereocenter (a carbon atom bonded to four different groups) or other elements that possess a plane of symmetry, often results in separation of the compound into two enantiomers when separated due to differences in the spatial orientation of their molecular structures. However, the lack of a chiral center within the compound's nucleus makes pseudoenantiomers distinct from well-known enantiomers; chiral features may still be present in parts of a compound not nucleus of a pseudoenantiomer such as organic functional groups.

These compounds have primarily been noted in chiral substitution mechanisms (CISM) that generate them in trace amounts when kinetic stereoselectivity fails to achieve trans diastereomeric product directly, substitution occurs directly generating nearly equal mixture in no definitive mirror imaged form resulting in false agreement.
