| Abstract: | The direct enantioseparation of 2-phenylpropanol, 2-phenylpropanal and 2-phenylpropanal dimethyl acetal was achieved, using enantioselective gas chromatography and heptakis-2,3-di-0-acetyl-6-0-tert.butyldimethylsilyl]- -cyclodextrin (DIAC--CD) or octakis-2,3-di-0-acetyl-6-0-tert.butyldimethylsilyl]- -cyclodex-trin (DIAC--CD) as the chiral stationary phase. Their odour characteristics and threshold values were investigated by enantioselective gas chromatography/olfactometry. Starting from commercially available (R)-2-phenylpropionic acid, enantiopure (R)-configured reference compounds were synthesized. |
