N-(4,4'-Dibromo-[1,1'-biphen­yl]-2-yl)benzamide

In the title compound, C₁₉H₁₃Br₂NO, the dihedral angle between the rings of the biphenyl group is 53.59 (14)°. The ring of the benzamide group is inclined to the phenyl rings of the biphenyl group by 23.87 (15) and 75.89 (15)°. There are no significant inter­molecular inter­actions in the crystal structure.

rac-4a,10b-cis,10b,5c-trans-5-(7-Methyl-2-oxo-2H-chromen-4-yl)-3,4,4a,5,6,10b-hexa­hydro-2H-pyrano[3,2-c]quinoline

In the racemic title compound, C₂₂H₂₁NO₃, the nitro­gen-containing ring of the pyran­oquinoline moiety adopts a slightly distorted half-chair conformation and the oxygen-containing ring adopts a slightly distorted chair conformation. The benzene rings make a dihedral angle of 84.97 (8)°. In the crystal, weak C—H...O inter­actions link the mol­ecules into chains extending along the a-axis direction.
