Abstract:The use of chiral stationary phases (CSPs) for the separation of enantiomers is commonplace. A variety of $\alpha$-alkyl and $\alpha$-aryl substituted $\alpha$-amino phosphonates were prepared. The ability of several CSPs to separate the enantiomers of N-(3,5-dinitrobenzoyl) derivatives of $\alpha$-alkyl and $\alpha$-aryl substituted $\alpha$-amino phosphonates was investigated. Using the chromatographic structure-activity relationships, chiral recognition models were proposed. For one class of CSP, the chiral recognition model has been further supported using spectroscopic and chromatographic evidence. Two $\alpha$-amino phosphonate derived CSPs were prepared and their ability to separate the enantiomers of a variety of analytes was studied. The mechanistic implications of analyte-CSP spatial complementarity were investigated. Two new CSPs derived from the 3,5-dinitrobenzamide of an $\alpha$-amino acid were prepared and evaluated.
