(2E)-2-Benzylidene-9-phenyl-3,4-dihydroacridin-1(2H)-one

T. Vinuchakkaravarthy, M. Sankaran, P. S. Mohan and D. Velmurugan

In the title compound, C₂₆H₁₉NO, the plane of the aromatic heterocycle makes a dihedral angle of 75.22 (4)° with that of the attached phenyl ring. In the crystal, molecules are connected by C—H

O interactions, generating R₂²(12) dimers. These dimers are further connected by C—H

π interactions, linking the molecules into chains running along the a-axis direction.

Keywords: crystal structure.

Comment top

Acridine is structurally related to anthracene with one of the central CH group replaced by nitrogen. Amsacrine which is an acridine derivative is clinically used for the treatment of cancer (Denny et al., 1982; Baguley & Ferguson, 1998). The strong activity of acridine derivatives is due to their ability to intercalate into DNA base pairs and leading to cell cycle arrest and apoptosis (Prommier et al., 2006).

The phenyl (C21—C26) and benzyl (C14—C20) rings deviate from the plane of the acridine system by 72.48 (6) ° and 49.24 (6) °, respectively. The crystal packing is stabilized by intermolecular C—H···O (C10—H10B···O1) interactions generating a R²₂(12) ring motif (Bernstein et al., 1995). These dimers are further connected by C—H···π (C26—H26···Cg1) interactions generating chains running along the a-axis.

Experimental top

A 1:2 molar mixture of 9-phenyl-3,4-dihydroacridin-1(2H)-one was treated with aromatic aldehydes in the presence of NaOH and allowed to stir at room temperature for 5–7 h. After completion of the reaction as inferred by the TLC, the mixture was poured into 200 g of crushed ice and neutralized with dil HCl. The precipitate thus formed after adding into crushed ice was filtered off and the residue subjected to column chromatography using petroleum ether: ethyl acetate mixture (3:1) v/v as eluent and compound obtained as a pale yellow solid.

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.
