The mol-ecular conformation of the title compound, C(20)H(17)N(3), is stabilized by an intramolecular C-H⋯N inter-action. The crystal structure shows inter-molecular C-H⋯π inter-actions. The dihedral angle between the isoquinoline unit and the phenyl ring is 11.42 (1)° whereas the isoquinoline unit and the pendent dimethyl pryrazole unit form a dihedral(More)
The asymmetric unit of the title compound, C(16)H(12)O(3), contains two crystallographically independent mol-ecules. The isochromene ring system is planar (maximum deviation 0.024 Å) and is oriented at dihedral angles of 2.63 (3) and 0.79 (3)° with respect to the methoxy-benzene rings in the two independent mol-ecules.
In the title moleclue, C(19)H(21)NO, the 4-piperidone ring adopts a chair conformation in which the two benzene rings and the methyl group attached to C atoms all have equatorial orientations. In the crystal structure, centrosymmetric dimers are formed through weak inter-molecular C-H⋯O hydrogen bonds [the dihedral angle between the aromatic rings is 58.51(More)
