AbstractChromatographic applications of three novel chiral stationary phases (CSPs) deriving from (S)‐(N)‐(3,5‐dinitrobenzoyl)tyrosine are reported, under liquid chromatographic (LC) and subscritical fluid chromatographic (SubFC) conditions. Two grafting modes of the chiral moiety have been experimented starting either from γ‐mercaptopropyl‐silanized (type 1) or γ‐aminopropyl‐silanized (type 2) silica gels. For type 2 CSPs an evaluation of the stability of the amide linkage was achieved by means of SubFC; the relative contriution of ionic and covalent bindings to the ciral recognitio aility was then outlined. The chromatographic properties of these CSPs were compared with those of the corresponding CSPs deriving from phenylglycine,p‐hydroxyphenylglycine, and phenylalanine for the resolution of some tertiary phosphine oxide, naphthoyl amide, and α‐methylene γ‐lactam enantiomers. Some simple requirements regarding the solute and CSP structures for chiral recognition ability can be inferred from these results. In addition, the resolutio of π‐acid α‐N‐(3,5‐dinitrobenzoyl)amino esters was investigated on these π‐acid CSPs. An example of preparative sc
