2,2,7,7-Tetra-methyl-1,2,3,4,5,6,7,8-octa-hydro-acridine-1,8-dione.

ABSTRACT: The whole molecule of the title compound, C17H21NO2, is generated by twofold rotational symmetry. The N atom and the C and H atoms in position 4 of the pyridine ring lie on the twofold axis. The cyclohexene ring has a sofa conformation with the CH2 C atom adjacent to the dimethyl-substituted C atom displaced by 0.5949?(16)?Å from the mean plane of the other five C atoms. In the crystal, weak C-H?O inter-actions link the mol-ecules into chains parallel to the a axis. In addition, ?-? stacking inter-actions [centroid-centroid distance = 3.8444?(7)?Å] contribute to the stabilization of the crystal structure.

The whole molecule of the title compound, C17H21NO2, is generated by twofold rotational symmetry. The N atom and the C and H atoms in position 4 of the pyridine ring lie on the twofold axis. The cyclohexene ring has a sofa conformation with the CH2 C atom adjacent to the dimethyl-substituted C atom displaced by 0.5949 (16) Å from the mean plane of the other five C atoms. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into chains parallel to the a axis. In addition, π-π stacking int ...[more]

Project description:The asymmetric unit of the title compound, C(25)H(31)NO(4), contains two independent mol-ecules. In one mol-ecule, the benzene ring and an attached meth-oxy group were refined as disordered over two sets of sites in a 0.65?(4): 0.35?(4) ratio. In both mol-ecules, the central ring of the acridinedione system adopts a flattened boat conformation. The four essentially planar atoms of this ring [maximum deviations = 0.006?(5)?Å in both mol-ecules] forms dihedral angles of 86.8?(2) and 87.6?(2)°, respectively, with the major and minor components in the disordered benzene ring and 87.3?(2)° with the benzene ring in the fully ordered mol-ecule. The two outer rings of the acridinedione system adopt sofa conformations in both mol-ecules. In the crystal, N-H?O hydrogen bonds form two independent chains along [100]. C-H?O hydrogen bonds link the chains, forming a three-dimensional network.

4a-Hy-droxy-3,3,6,6-tetra-methyl-9-[6-(3,3,6,6-tetra-methyl-1,8-dioxo-2,3,4,5,6,7,8,9-octa-hydro-1H-xanthen-9-yl)pyridin-2-yl]-2,3,4,4a,5,6,7,8,9,9a-deca-hydro-1H-xanthene-1,8-dione ethanol hemisolvate hemihydrate.

Project description:The pyridine ring in the title compound, C(39)H(47)NO(7)·0.5C(2)H(5)OH·0.5 H(2)O, is connected to one 3,3,6,6-tetra-methyl-1,8-dioxoxanthenyl and one 4a-hy-droxy-3,3,6,6-tetra-methyl-1,8-dioxodeca-hydroxanthenyl substituent in the 2- and 6-positions of the ring. In the former substituent, the six-membered xanthenyl ring adopts a flattened envelope conformation (with the methine C atom as the flap) while in the latter, the six-membered xanthenyl ring adopts a twisted envelope conformation (with the C atom bearing the hy-droxy group representing the flap). The hy-droxy H atom forms an intra-molecular hydrogen bond to the pyridyl N atom. An ethanol solvent mol-ecule is disordered with respect to a water mol-ecule in a 1:1 ratio. The water mol-ecule itself is disordered over two positions of equal occupancy.

10-(4-Chloro-phen-yl)-9-(4-fluoro-phen-yl)-3,3,6,6-tetra-methyl-3,4,6,7,9,10-hexa-hydro-acridine-1,8(2H,5H)-dione.

Project description:The title compound, C(29)H(29)ClFNO(2), was synthesized by the reaction of 4-fluoro-benzaldehyde, 5,5-dimethyl-cyclo-hexane-1,3-dione and 3-(4-chloro-phenyl-amino)-5,5-dimethyl-cyclo-hex-2-enone in an ionic liquid (1-butyl-3-methyl-imidazolium bromide). X-ray analysis reveals that the 1,4-dihydro-pyridine ring adopts a boat conformation, while each of the attached partially saturated six-membered rings adopts a half-chair conformation. The structure is stabilized by weak C-H?O and C-H?F hydrogen bonds. The mol-ecule has approximate mirror symmetry; the largest deviation from this symmetry concerns the fluoro- and chloro-phenyl rings.
