Abstract

This article describes a preparation of some new compounds of the aryloxyaminopropanol type derived from 4-hydroxyphenylpropan- 1-one with phenylamino, cyclohexylamino and isobutylamino group in the hydrophilic part and methoxymethyl or ethoxymethyl substituent in the lipophilic part of the molecule. The purity of the prepared compounds was checked by thinlayer chromatography and the structure was confirmed on the basis of interpretation of the IR, UV, 1H NMR and 13C NMR spectra. An enantioseparation of the prepared compounds was performed by using high-performance liquid chromatography on an amylase tris(3,5-dimethylphenylcarbamate) (Chiralpak AD) and native teicoplanin (Chirobiotic T). The chromatographic results such as retention, separation and resolution factors have shown that Chiralpak AD is more suitable for enantioseparation of some of the prepared compounds.

Abstract

Within the framework of the study of the synthesis and high-performance liquid chromatography (HPLC) enantioseparation the series of 9 derivatives of 3-hydroxyphenylethanone was prepared by a well-tried method. The structure of the prepared compounds was confirmed on the basis of interpretation of the IR, UV, 1H NMR and 13C NMR spectra. An enantioseparation of prepared compounds was performed using HPLC on a native teicoplanin (Chirobiotic T) and the amylose tris (3,5-dimethylphenylcarbamate) (Chiralpak AD) chiral stationary phases, which is more suitable for the enantioseparation of all prepared compounds especially with heterocycles in the basic part of a molecule.
