✦ Synopsis

The crystal structures of 1-pyrrolidino-2,4-dinitrobenzene (3) and 1-morpholino-2,4-dinitrobenzene (4) were determined by single-crystal x-ray diffraction and the structures in solution were investigated by UV-visible spectrophotometry and 13 C and 1 H NMR spectrosccopy. Compound 4 crystallizes in the monoclinic space group P2 1 / n with one independent molecule per asymmetric unit and 3 crystallizes in triclinic P-1 with three independent molecules per asymmetric unit. Rotation of the o-nitro group and of the amino group out of the aromatic plane was observed in both the solid state and in solution for both compounds.

l-fluoro-2,4-dinitrophenyl-5-L-alanine amide has been synthesized in high yield (76%) from 1,5-difluoro-2,4-dinitrobenzene and L-AIa-NH2. This compound contains a reactive fluorine atom which can be used for the reaction with a mixture of L-and D-amino acids. The resulting diastereomers which are ob
