एनेंटियोमेरिक इसके अंग्रेजी अर्थ का उदाहरण

The concentration of the olefin is crucial to the enantiomeric excess of the diol since higher concentrations of the alkene can associate with the other catalytic site to produce the other enantiomer.

After removal of the amine catalyst the ketone is effectively functionalized with a nucleophile and an electrophile with syn:anti ratio of 8:1 and 97% enantiomeric excess.

It is the enantiomeric partner of the (2R,5S) isomer: (+)- or d-menthone.

The reaction can be carried out in enantiomeric excess of up to 90% with the aid of bifunctional chiral BINOL and phosphinyl BINOL compounds, for example in the reaction of n-(4-chloro-benzylidene)-benzenesulfonamide with methyl vinyl ketone (MVK) in cyclopentyl methyl ether and toluene at -15°C.

This IL serves as the chiral solvent for the aza-BH reaction between N-(4-bromobenzylidene)-4-toluenesulfonamide and methyl vinyl ketone catalyzed by triphenylphosphine with chemical yield 34–39% and enantiomeric excess 71–84%.

Rapid equilibration between enantiomeric conformers and irreversible hydrogenation place the reaction under Curtin–Hammett control.
