Analysis by RP-HPLC and Purification by RP-SPE of the -Tetra(-hydroxyphenyl)resorcinolarene and Stereoisomers.
Abstract
A method for the separation of stereoisomer mixture of the octol -tetra(-hydroxyphenyl)calix[4]resorcinarene that was obtained by an acid cyclocondensation reaction between resorcinol and benzaldehyde is reported in this paper. A crude product from octol formation reaction was analyzed by reverse-phase high-performance liquid chromatography (RP-HPLC), and two well-resolved signals corresponding to the and isomers were found. A reverse phase in solid-phase extraction (RP-SPE) protocol allowed the separation of the two stereoisomers with high purity of each isomer. Finally, the crude and purified stereoisomers were characterized by using FT-IR, H-NMR, and C-NMR techniques, confirming the chemical identity of the two isomers and the efficiency in the separation process.
