摘要

Solid-phase derivatization reagents containing a 3,5-dinitrophenyl moiety for the derivatization of amines are described. The reagents are useful for Pirkle-type recognition of stereochemical composition of amines and related nucleophiles. The ability to stabilize 3,5-dinitrophenylisocyanate by covalent immobilization on a polymeric support varied greatly with the support chosen. The kinetics of the activated dinitrophenylcarbamate and the use of this reagent for enhanced recognition of optical purity is shown and compared to previous findings with a similar polymeric activated ester.
