Comment top

Chiral tertiary amines are efficient catalysts for direct aldol reactions of ketones with aldehydes (Paradowska et al., 2009). Therefore, it is of great interest for us to investigate the novel chiral tertiary amine as a chiral catalyst. In this article we would like to report the crystal structure of the title compound (I).

In (I) (Fig. 1), two tolyl rings form dihedral angles of 65.8 (1) and 6.6 (1)°, respectively, with the isoindole-1,3-dione mean plane. Cyclohexane ring adopts a chair conformation. This type of molecular geometry was reported also by Gawronski et al. (1998). It could be found that in the crystal structures the cyclohexane rings adopt chair conformations with phthalimide rings in equatorial orientation.

Experimental top

To a solution of (1R,2R)-N-phthaloyl-1,2-diaminocyclohexane (2.44 g, 10 mmol) (Kaik et al., 2003; Gawronski et al., 1998) in acetonitrile (50 ml) was added at room temperature K₂CO₃ (3.20 g, 23 mmol) and 4-methylbenzyl chloride (3 mL, 25 mmol). The mixture was refluxed with stirring for 5 h. The solvent was removed in vacuo and the mixture was extracted with dichloromethane and NaHCO₃ solution. The organic solution was dried over MgSO₄ and evaporated. Product was directly purified through flash column chromatography on a slilca gel to afford white solid. A crystal of (I) suitable for X-ray analysis was grown from diethyl ether by slow evaporation at room temperature.

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 of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
