Abstract
AbstractA two level full factorial design has been applied to quantify the effect of three selected structural parameters on the capacity factors and chiral separation of atropisomers in N‐arylthiazoline‐2‐(thi)‐ones derivatives on tris(p‐methylbenzoyl) cellulose beads. The behavior of the two enantiomers is influenced by different factors which might result from different retention sites within the same stationary phase. It appears that the two enantiomers behave independently on the CSP, the order of elution and separation being controlled by a minor steric modification in a very precise location in the molecule for one enantiomer. The methodology of the experimental design allows the comparison of equations generated from data issued from designed compounds. These equations afford much more information than the step by step comparison of individual molecules. In our case, the tris(p‐methylbenzoyl)cellulose beads and microcrystalline cellulose triacetate appear as complementary CSPs for the resolution of atropisomers of the series studied. © 1993 Wiley‐Liss, Inc.
