(1S, 2S), 1,3-Diacetoxy-1-(4-nitrophenyl)-2-propylisothiocyanate [(S,S)- DANI] has been developed as a new chiral derivatizing agent for resolution of compounds containing an amino group. The reagent is readily available in both enantiomeric forms. Its applicability was demonstrated by the resolution of representative α-amino acids. The diastereomeric thiourea derivatives produced were separated by reversed-phase (C18) high-performance liquid chromatography, with mixtures of 0.1% aqueous trifluoroacetic acid (pH ~ 2) and methanol as eluents.
