  Separation of enantiomers of 4-aryldihydropyrimidines by direct enantioselective HPLC. A critical comparison of chiral stationary phases

  摘要：

  The separation of the enantiomers of 29 racemic 4-aryldihydropyrimidine-5-carboxylates (DHPMs), aza-analogs of nifedipine-type dihydropyridine calcium channel modulators, was evaluated in direct enantioselective HPLC, employing the following commercially available chiral stationary phases (CSPs): Chiralcel OD-H, ChiraDex, Chirobiotic V and T, and Whelk-O1. In addition, a 1,2-diphenyl-1,2-diaminoethane based CSP and two quinine carbamate based chiral ion exchangers were also employed. For all 29 DHPMs separation of individual enantiomers could be achieved with at least one CSP with alpha-values ranging from 1.10 to 8.67. (C) 1997 Elsevier Science Ltd.
