Abstract: In the title compound, C18H15NO3, 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].
