Abstract: 
Here we report the synthesis of a novel covalently immobilized calix[4]arne derivative as a chiral stationary phase (CSP) for HPLC. In the structure of CSP, the upper rim of calix[4] arne is substituted with two L-alanine units and the lower rim of calix[4]arene is linked to the silica gel by thiol-ene click chemistry. Elemental analysis of the CSP showed 120 μ mol of chiral selector bonded per gram of silica gel. 1-Hexene was used for end-capping of unreacted mercapto groups on silica gel. The CSP is chemically bonded to the silica and can be used in the normal-phase mode, reversed-phase mode, and with halogenated solvents mobile phases, if desired. The chromatographic performance of the CSP was evaluated with enantioseparation of the 3, 5-dinitrobenzoyl (DNB) derivatives of some amino acids.
