Abstract

Abstract The synthesis of a chiral stationary phase (CSP) containing the 3,5-dinitrobenzoyl derivative of ( S,S)-1,2-diphenylethanediamine (DPEDA) as a chiral selector by immobilizing the DPEDA derivative onto glycidoxypropyl-modified silica gel and subsequent benzoylation is described. This so-called CSP-II showed high enantioselectivity under normal-phase conditions, in particular for chiral compounds containing a naphthylamide functionality.
