1-Methyl-3-p-tolyl-3,3a,4,9b-tetrahydro-1H-chromeno[4,3-c]isoxazole-3a-carbonitrile
In the title compound, C(19)H(18)N(2)O(2), the dihedral angle between the mean planes of the fused chromeno and isoxazole units is 43.71 (7)°. The isoxazole and pyran rings exhibit envelope and half chair conformations, respectively. The crystal packing is stabilized by inter-molecular C-H⋯π inter-actions.

In the title compound, C(10)H(12)N(2)S, the thio-phene ring is essentially planar (r.m.s. deviation = 0.0290 Å). The two C atoms of the cyclo-hexene ring (at positions 6 and 7) are disordered over two sets of sites in a 0.810 (5):0.190 (5) ratio. The cyclo-hexene rings in both the major and minor occupancy conformers adopt a half-chair conformation. In the crystal, there are two types of N-H⋯N ...

In the title compound, C(25)H(25)NO(3), the dihydro-pyran ring adopts a half-chair conformation, whereas the pyrrolidine ring is in a twist conformation. The tolyl group is oriented at an angle of 82.92 (7)° with respect to the napthalene ring system. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by C-H⋯π inter-actions involving the benzene ring of the tolyl group.
