Sažetak
The enhanced demand for enantiomerically pure compounds (EPC) has led to the development of a variety of enantioselective separation methods. Like very useful one emerged liquid chromatography which use chiral stationary phases (CSPs). One of the most used CSPs named brush or Pirkle type CSPs consist of small optically active compounds covalently bound to silica gel. Generally, mechanism of chiral recognition on this type of CSPs is based on noncovalent interactions (p-p interactions, hydrogen bonding attractions and van der Waals interactions) between enantiomers of analyte and CSP. Hydrogen bond is the most often achieved by the amide group, and p-p interactions by aromatic groups with strong p-donor or p-acceptor characteristic. Recently we have developed a number of original brush-type CSPs using 1, 3-dicyano-2, 4, 5, 6-tetrachlorobenzene as a branching achiral unit. Prepared CSPs achieved in some cases the excellent enantioseparations particularly for racemates with p-acceptor characteristics. Here we present the synthesis of the set of new chiral selectors with general structure I that imitate the structure of some previously described CSPs.
