In the title compound, C20H16BrNO2, the dihedral angle between the quinolone ring system mean plane (r.m.s. deviation = 0.018 Å) and the phenyl ring bridged by the ethynyl group, is 25.44 (14)°. There is an intra-molecular C-H⋯O hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds forming chains(More)
In the title compound, C21H21NO5, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.028 Å) and the tri-meth-oxy-benzene ring is 43.38 (5)°. The C atoms of the meth-oxy groups deviate from their attached benzene ring by -0.396 (2), -0.049 (2) and 0.192 (2) Å for the ortho-, meta- and para-substituents, respectively. The pendant ethyl(More)
