(Received 4 July 2013; accepted 4 July 2013; online 10 July 2013)

In the title compound, C₂₄H₂₄FN₃O₂S, the 1,3-thiazolidine ring adopts an envelope conformation with the S atom as the flap, while the cyclohexane ring is in a chair conformation. In the crystal, molecules are linked by N—H⋯O and C—H⋯F hydrogen bonds, forming a three-dimensional network. The unit cell contains six voids of 57 Å³, but the residual electron density (highest peak = 0.23 e Å⁻³ and deepest hole = −0.19 e Å⁻³) in the difference Fourier map suggests no solvent molecule occupies this void.

Comment top

Despite remarkable advances, tuberculosis and viral diseases continue to be the leading causes of death worldwide. Recent research on variously substituted N-(1-thia-4-azaspiro[4.5]dec-4-yl)carboxamides has revealed encouraging antitubercular (Cihan-Üstündağ & Çapan, 2012; Güzel et al. 2006; Ulusoy, 2002) and antiviral (Göktas et al., 2012; Vanderlinden et al., 2010) activity. Full characterization of the active core may yield invaluable data for the design of relevant compounds with enhanced action. Thus, we herein report the X-ray diffraction analysis of the title compound (I).

In (I), (Fig. 1), the 1,3 thiazolidine ring (S1/N3/C16/C17/C19) adopts an envelope conformation [the puckering parameters (Cremer & Pople, 1975) are Q(2) = 0.228 (3) Å and ϕ(2) = 351.3 (8)°] with the S1 atom as the flap atom. The cyclohexane ring (C19–C24) exhibits a chair conformation with the puckering parameters of Q_T = 0.554 (4) Å, θ = 180.0° and ϕ = 180 (15)°. The indole ring system (N1/C1–C7/C14) is essentially planar, with the maximum deviations of 0.014 (2) Å for N1 and 0.012 (3) Å for C5. The phenyl (C8–C13) and 1,3-thiazolidine (S1/N3/C16/C17/C19) rings are inclined at the dihedral angles of 56.14 (15) and 57.03 (12) °, respectively, to the indole ring system. The torsion angle of the N3–N2–C15–C14 bridge between the indole ring and the thiazolidine ring system is -165.8 (2) °.

In the crystal structure, N—H···O and C—H···F hydrogen bonds connect the adjacent molecules to each other, forming a three dimensional network. In addtion, π-π and C—H···π interactions are not observed.

Experimental top

A mixture of 5-fluoro-3-phenyl-1H-indole-2-carbohydrazide (0.0025 mol), cyclohexanone (0.003 mol) and 2-mercaptopropionic acid (0.01 mol) was refluxed in 20 ml dry benzene for 5 h using a Dean-Stark water separator. Excess benzene was evaporated in vacuo. The resulting residue was triturated with saturated NaHCO₃ solution until CO₂ evolution ceased and was refrigerated overnight. The solid thus obtained was washed with water, filtered, dried, and recrystallized from ethanol.

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 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 > σ(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.
