Five new chiral derivatizing reagents 5-hydrazino-2,4-dinitrophenyl-l-alaninamide (HDNP-l-Ala-NH2), 5-hydrazino-2,4-dinitrophenyl-l-phenylalaninamide (HDNP-l-Phe-NH2), 5-hydrazino-2,4-dinitrophenyl-l-valinamide (HDNP-l-Val-NH2), 5-hydrazino-2,4-dinitrophenyl-l-leucinamide (HDNP-l-Leu-NH2) and 5-hydrazino-2,4-dinitrophenyl-l-phenylglycinamide (HDNP-d-Phg-NH2) were synthesized by straightforward two-step synthesis starting from 1,5-difluoro-2,4-dinitrobenzene. Nucleophilic substitution of one fluorine atom in DFDNB with different amino acid amides yielded Marfey's
