In the title compound, C13H13NO, the dihedral angle between the benzene ring and the fused pyrrole ring is 0.96 (7)°. The cyclohexenone ring adopts an envelope conformation. Inter­molecular N—H...O hydrogen bonds form R22(10) ring motifs in the crystal structure. Weak C—H...π inter­actions involving the benzene ring also occur.

Comment top

Tetrahydrocarbazolones have been used extensively as advanced intermediates in synthetic efforts toward a number of naturally occurring carbazole alkaloids (Bringmann et al., (1995); Chakravarty et al., (2001); Knölker & Reddy (2002); Lin & Zhang (2000); Matsuo & Ishida (1994); Miki & Hachiken (1993); Scott et al., (2006)). Jean et al. (2004) and Knölker & Reddy (2008) have reported biologically active carbazoles. The preparation of 1-oxo compounds via their corresponding hydrazones have been reported (Rajendra Prasad & Vijayalakshmi (1994)).

Thomas Gunaseelan et al. (2009), Sridharan et al. (2008) and Thiruvalluvar et al. (2007) have reported the crystal structures of substituted carbazole derivatives, in which the carbazole units are not planar. In the title molecule (Scheme I, Fig. 1), C13H13NO, the carbazole unit is not planar. The dihedral angle between the benzene ring and the fused pyrrole ring is 0.96 (7)°. The r.m.s. deviation of a mean plane fitted through all non hydrogen atoms excluding C3 of the carbazole unit is 0.0180 Å; C3 deviates from this plane by 0.620 (2) Å. The cyclohexene ring adopts an envelope conformation. The puckering parameters (Cremer & Pople, 1975) are q2=0.3623 (14) Å, q3=-0.2730 (14) Å, Q=0.4536 (14) Å, θ=127.00 (18)° and φ=292.7 (2)°. Intermolecular N9—H9···O1 hydrogen bonds form a R22(10)(Bernstein et al., 1995) ring motif in the crystal structure (Table 1, Fig. 2). Weak C2—H2B···π and C5—H5···π interactions involving the benzene (C4B,C5—C8,C8A) ring are also found in the structure(Table 1).

Experimental top

A solution of 2-(2-o-tolylhydrazono)-cyclohexanone (0.216 g, 0.001 mol) in a mixture of acetic acid (20 ml) and hydrochloric acid (5 ml) was refluxed on an oil bath pre-heated to 398 K for 2 h. The contents were then cooled and poured onto cold water with stirring. The brown solid which was separated by passing through a column of silica gel and eluted with (98:2, v/v) petroleum ether: ethyl acetate mixture to yield the title compound (0.126 g, 63%). This was recrystallized from ethanol.

Refinement top

The H atom bonded to N9 was located in a difference Fourier map and refined freely. Other H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.95–0.99 Å and Uiso(H) = 1.2–1.5Ueq(parent atom).

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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 > 2σ(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.
