چکیده
The ring skeleton of the title compound, C(14)H(4)Cl(2)N(2)O(6), is close to planar (r.m.s. deviation of the carbon atoms 0.091 Å); the nitro goups are twisted with respect to the mean plane of the ring system by 70.8 (1) and 86.7 (2)°. The crystal studied was found to be a merohedral twin, with a domain ratio of 0.61 (8):0.39 (8).

"One Pot" Synthesis of 1,5-Diaza-2,3,6,7-Thetrahydro-4-Methyl-Phenanthrene-4,8-Dione From Corresponding Bis-Beta-Amino Acid
The cyclization of b-anilino propionic acids in the presence of polyphosphoric acid (PPA) afforded the 2,3-Dihydroquinoline-4-(1H)-ones in good yields. N,N'-bis(2-carboxyethyl)-4-methyl-1,2-diaminobenzene (7) is cyclized under this condition to produce the 1,5-diaza-2,3,6,7-tetrahydro-4-methyl-pheranthrene-4,8-dione(bis-quinolone) (8).
