In the title compound, C20H21NO2, the pyrrolidine ring adopts an envelope conformation with the N atom at the flap position. The central benzene ring makes dihedral angles of 21.39 (10) and 80.10 (15)° with the phenyl ring and the mean plane of the pyrrolidine ring, respectively. The mol­ecular conformation is stabilized by an intra­molecular O—H⋯N hydrogen bond, which closes an S(6) ring. A weak C—H⋯π inter­action is observed in the crystal.

1. Chemical context

Mannich bases are a group of compounds having various biological activities such as cytotoxic (Bilginer et al., 2013[Bilginer, S., Gul, H. I., Mete, E., Das, U., Sakagami, H., Umemura, N. & Dimmock, J. R. (2013). J. Enzyme Inhib. Med. Chem. 28, 974-980.]), anti-inflammatory (Sahin et al., 2010[Sahin, Y. N., Demircan, B., Suleyman, H., Aksoy, H. & Gul, H. I. (2010). Turk. J. Med. Sci. 40, 723-728.]) and anti­convulsant (Gul et al., 2004[Gul, H. I., Calis, U. & Vepsalainen, J. (2004). Arzn. Fors. 54, 359-364.]) activities. α,β-Unsaturated ketones present in the chemical structure of Mannich bases themselves or those produced from them by deamination processes are responsible for their cytotoxicity.

[Scheme 1]

The cytotoxic and anti­cancer properties of chalcone (1,3-diphenyl-2-propenone) and related compounds have been reported (Bilginer et al., 2013[Bilginer, S., Gul, H. I., Mete, E., Das, U., Sakagami, H., Umemura, N. & Dimmock, J. R. (2013). J. Enzyme Inhib. Med. Chem. 28, 974-980.]; Dimmock et al., 1998[Dimmock, J. R., Kandepu, N. M., Hetherington, M., Quail, J. W., Pugazhenthi, U., Sudom, A. M., Chamankhah, M., Rose, P., Pass, E., Allen, T. M., Halleran, S., Szydlowski, J., Mutus, B., Tannous, M., Manavathu, E. K., Myers, T. G., De Clercq, E. & Balzarini, J. (1998). J. Med. Chem. 41, 1014-1026.]; Gul Cizmecioglu et al., 2009[Gul, H. I., Cizmecioglu, M., Zencir, S., Gul, M., Canturk, P., Atalay, M. & Topcu, Z. (2009). J. Enzyme Inhib. Med. Chem. 24, 804-807.]); Gul Mete et al., 2009[Gul, M., Mete, E., Atalay, M., Arik, M. & Gul, H. I. (2009). Arzn. Fors. Drug. Res. , 59, 364-369.]). The title compound, (I)[link], reported in this study is a Mannich base of phenolic chalcone.

2. Structural commentary

In the title compound (Fig. 1[link]), the pyrrolidine ring (N1/C17–C20) exhibits an envelope conformation with the N atom at the flap position [the puckering parameters are Q(2) = 0.350 (3) Å and φ(2) = 186.9 (5)°]. The central benzene ring (C10–C15) makes dihedral angles of 21.39 (10) and 80.10 (15)°, with the phenyl ring (C1–C6) and the mean plane of the pyrrolidine ring (N1/C17–C20), respectively. Otherwise, the geometrical parameters for (I)[link] are comparable those reported for related compounds (Suhud et al., 2015[Suhud, K., Heng, L. Y., Hasbullah, S. A., Ahmad, M. & Kassim, M. B. (2015). Acta Cryst. E71, o225-o226.]; Palakshamurthy et al., 2012[Palakshamurthy, B. S., Srinivasa, H. T., Kumar, V., Sreenivasa, S. & Devarajegowda, H. C. (2012). Acta Cryst. E68, o3382.]). An intra­molecular O2—H1O⋯N1 hydrogen bond (Table 1[link], Fig. 2[link]) helps to establish the mol­ecular conformation of (I)[link].

3. Supra­molecular features

The only directional inter­action present in the crystal of (I)[link] is a very weak C—H⋯π bond (Table 1[link]).

4. Semi-empirical quantum-mechanical calculations

A theoretical calculation was carried out using the semi-empirical quantum-mechanical CNDO/2 (Complete Neglect of Differential Overlap) method (Pople & Beveridge, 1970[Pople, J. A. & Beveridge, D. L. (1970). In Approximate Molecular Orbital Theory. New York: McGraw-Hill.]). The spatial view of the single mol­ecule, with atomic labels, calculated as a closed-shell in a vacuum is shown in Fig. 3[link]. The charges at atoms O1, O2 and N1 are −0.337, −0.271 and −0.159 e, respectively. The calculated dipole moment is 2.760 Debye.

5. Biological activity

Compound (I)[link] was tested against human hepatoma (Huh7) and breast cancer cell (T47D) lines in terms of its cytotoxic activities, and showed activities against both cell lines used, especially against the T47D cell line. The compound studied here may serve as a model compound for designing new anti­cancer compounds for further studies (Yerdelen, 2009[Yerdelen, K. O. (2009). PhD thesis, Health Sciences, Atatürk University, Erzurum, Turkey.]).

6. Synthesis and crystallization

A solution of paraformaldehyde (0.132 g; 4.4 mmol) and pyrrolidine (0.317 g, 4.4 mmol) in aceto­nitrile (5 mL) was heated under reflux at 353 K for 30 min. A solution of the chalcone, 1-(4-hy­droxy­phen­yl)-3-phenyl-2-propen-1-one (1 g, 4.4 mmol) in aceto­nitrile (25 ml), was added to the reaction flask and heating was continued. The reaction was monitored by thin layer chromatography (TLC) and stopped after 7.5 h. The reaction solvent was distilled under vacuum. The residue was purified by column chromatography using Al2O3 as adsorbant and CHCl3/MeOH (9:1) as eluent. The title compound was obtained in 44% yield (m.p. = 398–402 K).Crystals suitable for X-ray diffaction analysis were obtained by recrystallization from ehanol.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. Carbon-bound H atoms were placed in calculated positions with C—H = 0.93 and 0.97 Å, and refined using a riding model with Uiso(H) = 1.2Ueq(C). The hydroxyl H atom was found from a difference Fourier map and its positional parameters were freely refined with Uiso(H) = 1.5Ueq(O). The most disagreeable reflections (2 4 0), (4 9 0), (4 12 0), (5 12 4), (3 12 5), (3 3 1), (0 16 5), (1 3 0), (2 20 6), (−2 13 17), (0 5 4), (0 11 4) and (2 13 4) were omitted in the final cycles of refinement. The Flack absolute structure parameter was found to be indeterminate in the present study.

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 esds are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > 2sigma(F2) is used only for calculating -R-factor-obs 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.
