Xylose Isomerase Catalysed Novel Hexose Epimerization
Biocatalysis and Biotransformation, 1999Novel hexose substrates and new epimerization reactions catalysed by the industrially important D-xylose ketol-isomerase (E.C. 5. 3. 1. 5.) are described. Isomerization equilibrium betweer D-allose and D-psicose or D-sorbose and D-gulose is obtained starting from either of the substrates.

Fluoroalkoxyphosphonium ylids. Epimerization and transformations
Tetrahedron Letters, 1994Abstract Dehydrofluorination of alkoxydifluorophosphoranes 2, containing chiral alkoxygroup, by organometallic bases passes under conditions of kinetic control to afford diastereomeres of ylid 3 in the proportion 1:1. In the presence of lithium salts the epimerization of 3 leads to the formation of the most thermodynamic stable diastereomere ...

1.5.1 Racemization and Epimerization
2015AbstractBiocatalytic racemization represents the reversible interconversion of an enantiomer to its mirror image and is catalyzed by racemases. In the context of organic synthesis, it represents the key step to turn a kinetic resolution into a dynamic process.
