چکیده
The asymmetric unit of the title compound, C10H14N2O3, contains two independent mol-ecules with similar conformations. In the both mol-ecules, the cyclo-hexene rings adopt the same envelope conformation with the flap C atoms lying 0.658 (3) and 0.668 (3) Å from the mean planes formed by the remaining atoms. In the crystal, adjacent mol-ecules are connected via N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, forming supra-molecular layers parallel to (-101).

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.

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 link...

Five of the atoms of the six-membered cyclo-hexene ring of the title compound, C(17)H(20)O(2), are essentially coplanar (r.m.s. deviation = 0.006 Å), with the sixth (the dimethyl-methyl C atom) deviating from the mean plane of the five atoms by 0.610 (2) Å. This plane is nearly perpendicular to the cinnamyl portion, the two planes being aligned at 85.1 (1)°. Two mol-ecules are linked by an O-H⋯...

The asymmetric unit of the title compound, C(21)H(26)O(4)S, consists of two independent mol-ecules. In both mol-ecules, intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular structure. In the crystal, each mol-ecule and its symmetry-related mol-ecule by twofold rotation form a dimer through a pair of inter-molecular C-H⋯O hydrogen bonds. In one of the mol-ecules, the thio-phene group is...

In the title compound, C25H29FO4, each cyclo-hexenone ring has an envelope conformation with the dimethyl-substituted atom as the flap. The hy-droxy and carbonyl groups form two intra-molecular O-H⋯O hydrogen bonds, as is typical for xanthene derivatives. In the crystal, very weak C-H⋯O hydrogen bonds link mol-ecules into dimers.
