HPLC and TLC enantioseparation of the nitro-positioned aryloxysubstituted aminopropanols.

摘要

An enantioseparation study of nitro-substituted aryloxyaminopropanols was performed using HPLC on a teicoplanin chiral stationary phase and TLC impregnated with L-aspartic and L-tartaric acid as chiral selectors. The type of substituent on the nitrogen in the hydrophilic part of molecule is essential for excellent separation by HPLC. L-aspartic acid seems to be a suitable chiral selector for enantioseparation by TLC.
