Enantioseparation of 2-aryl-1,3-dicarbonyl analogues by high performance liquid chromatography using polysaccharide type chiral stationary phase

Chirality. 2008 Feb;20(2):147-50. doi: 10.1002/chir.20513.

Abstract

The HPLC chiral separation of 21 kinds of 2-aryl-1,3-dicarbonyl analogues was investigated in normal phase mode with amylose tris(3,5-dimethylphenylcarbamate), amylose tris((S)-1-phenylethylcarbamate), cellulose tris(3,5-dimethylphenylcarbamate), and cellulose tris(4-methylbenzoate) chiral stationary phases, respectively. The whole set of 2-aryl-1,3-dicarbonyl analogues shows better enantioselectivity and enantioseparation on amylose tris(3,5-dimethylphenyl carbamate) (Chiralpak AD-H). The temperature dependence of enantioselectivity was studied to improve the enantioseparation. In addition, efforts are made to relate analyte structure with the quality of the achieved chiral separation.
