چکیده
The title compound, C(11)H(16)O(3), was obtained by reaction of dimedone, 5,5-dimethylcyclohexane-1,3-dione, and α-chloro-acetone. The cyclo-hexenone ring exhibits an envelope conformation with puckering amplitudes Q = 0.433 (2) and Φ = -109.0 (3)°. The 2-oxopropyl fragment is almost perpendicular to the cyclo-hexa-none ring [dihedral angle = 77.72 (8)°]. In the crystal, the mol-ecules are linked to each other through O-H⋯O hydrogen bonding, building a chain parallel to the b axis.

The mol-ecule of the title compound, C(18)H(17)N(3), with the exception of the -C(CH(3))(2) group, is nearly planar [maximum deviation: 0.208 (4), r.m.s. deviation 0.099 (6) Å] and the disubstituted C atom is displaced by 0.679 (2) Å from the mean plane through the remaining non-H atoms. In the crystal, the packing is stabilized by weak C-H⋯π inter-actions.
