In the title compound, C~16~H~12~O~3~, the dihedral angle between the benzene rings is 12.0 (1)°. In the crystal structure, the molecules are linked through π–π interactions and C–H...π (arene) hydrogen-bonding interactions.
The extent of enantiomeric excess in the 8-methylation of chalcone ~\_\_\_~ by ckira7, cuppates is shown to depend strongly on small structural modifications of the ligands, all of which are derived from the basic carbon framework of L-prolinol. Enantiomepic excesses up to 88% have been realised.
In the title compound, C 17 H 16 N 2 O 3 , the dihedral angle between the benzene rings is 1.56 (7) . The nitro group is coplanar with the attached benzene ring while the dimethylamino group is twisted slightly away from the attached benzene ring. A weak intramolecular C-HÁ Á ÁO hydrogen bond is pre
