  Synthesis of deoxycholic-derived chiral stationary phases possessing both arylcarbamate and arylamide moieties: evaluation of their chiral discrimination properties in the HPLC resolution of racemic compounds

  摘要：

  Two families of chiral selectors derived from deoxycholic acid, possessing both an arylamide and an arylcarbamate group on the cholestanic backbone were synthesized and covalently bonded to silica gel to afford new chiral stationary phases (CSPs A1-D1 and A2-D2) for the HPLC resolution of racemic compounds. The chromatographic data concerning the resolution of selected racemic compounds on CSPs A1-D1 and A2-D2 were compared with those obtained using analogous CSPs possessing only arylcarbamate groups on the cholestanic system (CSPs A-D). This has allowed its to establish that the resolution capability of CSPs A1-D1 and A2-D2 depends not only on the position of the arylamide group on the cholestanic backbone, but also on the electronic characteristics of the aromatic substituents.
