Exempel på hur man kan använda ENANTIOENRICHED i en mening

• In another experiment cluster formation of a racemic mixture with deuterium enriched L-serine results in a product distribution with hardly any 50/50 D/L clusters but a preference for either D or L enantioenriched clusters.
• Enantiomer self-disproportionation is a process in stereochemistry describing the separation of a non-racemic mixture of enantiomers in an enantioenriched fraction and a more racemic fraction as a result of the formation of heterochiral or homochiral aggregates.
• Complexes derived from the chiral phosphines can catalyse reactions to give chiral, enantioenriched products.
• The enantiomers are then derivatized to diastereomeric carbamates using enantioenriched 1-(1-Naphthyl)ethyl isocyanate (also developed by Pirkle).
• In a study in which an enantioenriched substituted cyclopropyl Grignard reagent was prepared, the reaction was shown to give the allene with very high levels of enantiospecificity, suggesting a concerted mechanism.
• Though the latter step is still commonly used for functionalization of stannatrane chloride to simple alkyl derivatives via transmetalation, Biscoe and coworkers have developed a lithiation method that provides access to a variety of enantioenriched alkyl substituents from optically active mesylates (2).
• Difluorinated silyl enol ethers are involved to produce enantioenriched fluoroalkyl-functionalized isoindolones first.
