The 4H-pyran ring of the title compound, C(17)H(16)N(2)O(2), is nearly planar [maximum deviation = 0.077 (2) Å] and the cyclo-hexene ring adopts a flattened chair conformation [puckering parameters: Q(T) = 0.435 (2) Å, θ = 122.0 (3)° and ϕ = 53.5 (3)°]. The 4H-pyran ring is almost perpendicular to the benzene ring [dihedral angle = 87.23 (8)°] and is almost coplanar with the mean plane of the c...

The title compound, C(17)H(16)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. In both mol-ecules, the fused cyclo-hexenone ring adopts a sofa conformation. In the crystal, N-H⋯N and N-H⋯O hydrogen bonds link the mol-ecules into corrugated layers parallel to the (101) plane.

In the title moleclue, C(16)H(13)ClN(2)O(2), the cyclo-hexene ring is in a sofa conformation. The pyran ring is essentialy planar [maximum deviation = 0.038 (2) Å] and forms a dihedral angle of 89.68 (10)° with the benzene ring. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers with R(2) (2)(12) ring motifs. These dimers are further linked by N-H⋯O...
