[Studies on the chiroptical properties of 2,4-dinitrophenyl derivatives of amino compounds of pharmaceutical interest].

Some results on the chiroptical properties of 2,4-dinitrophenylaminoacids reported in the literature, have been re-examined since they were in disagreement with our earlier research. Extension of this research to several sympathomimetic amines, demonstrates that the chiroptical properties of these derivatives show coherent behaviour; as a consequence the absolute configuration of the amino compounds condensed with Sanger reagent can be correlated to the sign of their higher wavelength Cotton effect.
