Abstract
Background:
Tetralone derivatives, important resources for the development of new drugs
which can act in the treatment of central nervous system disorders or participate in synthesis reaction
for the synthesis of various pharmaceuticals, have great research value and a bright prospect in exploitation.
Methods:
A novel chiral HPLC method for efficient enantioseparation of eight tetralone derivative enantiomers
was developed on cellulose based CHIRALPAK IC chiral stationary phase under normal
mode by investigating the effects of type and content of organic modifier, column temperature and flow
rate on retention and enantioselectivity. Besides, the specificity, linearity, stability, precision, accuracy
and robustness of this method were also validated.
Results:
Satisfactory enantioseparation was obtained for all enantiomers in n-hexane/2-propanol mobile
phase system at ambient temperature. The thermodynamic study indicated that the solute transfer from
the mobile to stationary phase was enthalpically favorable, and the process of enantioseparation was
mainly enthalpy controlled. This method met the requirements for quantitative determination of tetralone
derivative enantiomers.
Conclusion:
This study can provide great and important application value for enantioseparation of eight
pairs of newly synthesized tetralone derivative enantiomers under normal mode using CHIRALPAK IC
chiral column.

Abstract
An up-to-date overview of thin-layer chromatography (TLC) techniques for chiral separations of various significant and/or recent examples of enantioresolutions is reported. Furthermore, examples for chiral separations obtained on achiral commercially available C18 TLC plates are described in detail. These include the enantioseparation of methylthiohydantoin-phenylalanine and methylthiohydantoin-tyrosine using hydroxyethyl-β-cyclodextrin as mobile phase additive and the separation of the enantiomers of warfarin and p-chlorowarfarin using bovine serum albumin as mobile phase additive.
