  • Diastereomeric recrystallization — is a method of chiral resolution of enantiomers from a racemic mixture. It differs from asymmetric synthesis, which aims to produce a single enantiomer from the beginning, in that diastereomeric recrystallization separates two enantiomers that… …   Wikipedia

  • Enantiomeric excess — The enantiomeric excess of a substance is a measure of how pure it is. In this case, the impurity is the undesired enantiomer (the opposite handed mirror image of a chiral compound). Definition Enantiomeric excess is defined as the absolute… …   Wikipedia

  • Kinetic resolution — In kinetic resolution, two enantiomers show different reaction rates in a chemical reaction, thereby creating an excess of the less reactive enantiomer.[1] This excess goes through a maximum and disappears on full completion of the reaction.… …   Wikipedia
