8,8-Dimethyl-8,9-dihydro-7H-chromeno[2,3-b]quinoline-10,12-dione

In the title compound, C(18)H(15)NO(3), the fused benzopyran and pyridine rings are essentially coplanar [r.m.s. deviation = 0.0533 Å with a maximum deviation of 0.080 (1) Å for a benzene C atom]. The cyclo­hexa­none ring adopts an envelope conformation with the dimethyl-substituted C atom 0.660 (2)...

description In the title compound, C(18)H(15)NO(3), the fused benzopyran and pyridine rings are essentially coplanar [r.m.s. deviation = 0.0533 Å with a maximum deviation of 0.080 (1) Å for a benzene C atom]. The cyclo­hexa­none ring adopts an envelope conformation with the dimethyl-substituted C atom 0.660 (2) Å out of the plane formed by the remaining ring atoms (r.m.s. deviation = 0.0305 Å). The dihedral angle between the mean planes of the pyran and cyclo­hexa­none rings is 12.95 (6)°. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds, leading to chains running along [011].
