چکیده
In the title compound, C(20)H(17)N(3)O(3), the dihedral angles between the central pyridine ring and the two terminal rings are 15.07 (3) and 43.24 (3)°. The dihedral angle between the two terminal rings is 37.49 (4)° In the crystal, inter-molecular amine N-H⋯N(nitrile) hydrogen-bonding inter-actions form inversion dimers, which are linked into chains through amine N-H⋯O(meth-oxy) hydrogen bonds.

In the title compound, C(25)H(32)O(7), the 3-hy-droxy-5,5-dimethyl-cyclo-hex-2-enone rings adopt slightly distorted envelope conformations with the two planes at the base of the envelope forming dihedral angles of 57.6 (4) and 53.9 (9)° with the benzene ring. There is an intra-molecular hy-droxy-ketone O-H⋯O inter-action between the two substituted cyclo-hexane rings as well as a short intra-mo...

In title compound, C(10)H(12)O(4), all of the non-H atoms lie approximately in a plane with the largest deviation being 0.061 (2) Å. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. No classical inter-molecular hydrogen bonding occurs, with only van der Waals forces stabilizing the crystal structure.
