In the title compound, C₁₇H₁₇NO₄, the cylohexane-1,3-dione ring adopts an envelope conformation with the dimethyl-subsituted C atom as the flap. Its mean plane is inclined to the benzene ring by 7.99 (19)°. The molecule has a trans conformation about the bridging C=C bonds of the allyidene chain. In the crystal, molecules are linked via pairs of C—H⋯O hydrogen bonds, forming inversion dimers. The dimers are linked by further C—H.·O hydrogen bonds, forming sheets lying parallel to (10-1).

Keywords: crystal structure; cyclohexane-1,3-dione; dimedone.

Experimental top

To solution of 5,5-Dimethyl-1,3-cyclohexanedione (1.84 mmol), 4-nitrocinnamaldehyde(1.84 mmol) and 4 Å MS was added catalytic amounts of L-proline in under nitrogen atmosphere. The anhydrous ethyl acetate (2 ml) was added to a reaction mixture and the solution was stirred at room temperature for 3 h. The progress of reaction was monitored by TLC. After completion of reaction, the reaction mixture was filtered through pad of celite to remove MS and evaporation of the solvent afforded a mixture. The mixture was purified by flash column chromatography(EA: Hex = 1: 3) to afford the title compound as a colorless solid in yield 62%. Recrystallization from ethanol gave crystals suitable for X-ray analysis.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F². R-factor (gt) are based on F. The threshold expression of F² > 2.0 σ(F²) is used only for calculating R-factor (gt).
