Summary
β-Cyclodextrin is applied as the chiral component of the mobile phase in a systematic study of the resolution —into enantiomers — of mandelic acid and its derivatives by reversed-phase liquid chromatography. It is found that the stereoselectivity arising from inclusion in β-cyclodextrin molecules is significant (α=1.02÷1.05) only for the compounds showing at the asymmetric carbon atom the presence of first, an intact carboxylic group and second, a functional group capable of hydrogen bonding with the hydroxyl groups of β-cyclodextrin. Results are discussed in the light of the three-point attachment model of stereoselectivity as well as of the structure of the inclusion complexes.
