IMMOBILIZED CROWN COMPOUNDS AS ADSORBENT IN THE COLUMN CHROMATOGRAPHY
The racemate of L-a-alanine ester-2-butanol, propylene oxide were separated into their individual diastereoisorners, using immobilized crown ether as adsorbent by column chromatograpy. The resulting diastereoisomers were hydrolyzed and converted into the enantiomers. The structure of the enantiomers have been confirmed by physico-chemical methods.
Keywords : crown ether, enantiomer, diastereoisomer, oligomer, immobilized crown, column chromatography, optical selectivity, eluent
