The title compound, C13H19N3OS, is a new thia­zolidin-4-one derivative prepared and isolated as the pure (3aS,6R)-diastereisomer from (R)-thio­semicarbazone pulegone. It crystallized with two independent mol­ecules (A and B) in the asymmetric unit. The compound is composed of a hexhydro­indazole ring system (viz. a five-membered di­hydro­pyrazole ring fused to a cyclo­hexyl ring) with a thia­zole-4-one ring system attached to one of the pyrazole N atoms (at position 2). The overall geometry of the two mol­ecules differs slightly, with the mean planes of the pyrazole and thia­zole rings being inclined to one another by 10.4 (1)° in mol­ecule A and 0.9 (1)° in mol­ecule B. In the crystal, the A and B mol­ecules are linked via C—H⋯O hydrogen bonds, forming slabs parallel to the ab plane. There are C—H⋯π inter­actions present within the layers, and between the layers, so forming a three-dimensional structure.

1. Chemical context

Thia­zolidinones constitute an important class of heterocyclic compounds containing sulfur and nitro­gen in a five-membered ring. They play a vital role due to their wide range of biological activities and industrial importance. Thia­zolidin-4-ones are particularly important because of their efficiency towards various pharmacological usages. A recent literature search reveals that thia­zolidin-4-one derivatives may exhibit anti­bacterial (Bonde & Gaikwad, 2004[Bonde, C. G. & Gaikwad, N. J. (2004). Bioorg. Med. Chem. 12, 2151-2161.]), anti­tuberculosis (Karali et al., 2007[Karalı, N., Gürsoy, A., Kandemirli, F., Shvets, N., Kaynak, F. B., Özbey, S., Kovalishyn, V. & Dimoglo, A. (2007). Bioorg. Med. Chem. 15, 5888-5904.]), anti­viral (Kaushik-Basu et al., 2008[Kaushik-Basu, N., Bopda-Waffo, A., Talele, T. T., Basu, A., Chen, Y. & Küçükgüzel, Ş. G. (2008). Front. Biosci. 13, 3857-3868.]) and anti­cancer activities (Patel et al., 2014[Patel, A. B., Chikhalia, K. H. & Kumari, P. (2014). J. Saudi Chem. Soc. 18, 646-656.]).

As a part of our endeavour toward the preparation of new heterocyclic systems, we report herein on the structure of a new optically active thia­zolidin-4-one (2) synthesized from (R)-thio­semicarbazone pulegone (1); see Scheme. The reaction involves the treatment of thio­semicarbazone (1), in

[Scheme 1]
refluxing ethanol, with ethyl bromo­acatete and an excess of sodium acetate. Crystallization from an ethano­lic solution of the resulting indazolic thia­zolidin-4-one (obtained as a diastereomeric mixture) led to the isolation of compound (2). The structure of (2) was elucidated using spectroscopic (MS and NMR) data, while its absolute structure was determined as (3aS,6R) based mainly on the synthetic pathway and confirmed by resonant scattering.

2. Structural commentary

The title compound crystallized with two independent mol­ecules (A and B) in the asymmetric unit. The compound is composed of a hexhydro­indazole ring system [viz. a five-membered di­hydro­pyrazole ring fused to a cyclo­hexyl ring] with a thia­zole-4-one ring system attached to pyrazole N atom N2 (Fig. 1[link]). Mol­ecular fitting of the two mol­ecules (Spek, 2009[Spek, A. L. (2009). Acta Cryst. D65, 148-155.]) shows that they have roughly the same conformation and the same configuration (Fig. 2[link]), even if some slight differences can be observed. The six-membered rings each display a chair conformation, with puckering parameters of θ = 12.96° and φ2 = 113.49° for mol­ecule A and θ = 9.44° and φ2 = 92.43° for mol­ecule B. The five-membered pyrazol rings are almost planar with the largest deviation being 0.081 (3) Å for atom C3 in mol­ecule A and −0.032 (1) for atom C3B in mol­ecule B. The thia­zole rings are planar, the largest deviation being −0.011 (1) Å for atom C2′ and 0.005 (1) for atom C5′B in mol­ecules A and B, respectively. In mol­ecule A, the two five-membered rings are slightly twisted with a dihedral angle of 10.4 (1)°, whereas in mol­ecule B the two rings are almost coplanar with a dihedral angle of 0.9 (1)°.

3. Supra­molecular features

In the crystal, the two independent mol­ecules are connected via C—H⋯O hydrogen bonds forming layers, or slabs, parallel to the ab plane (Table 1[link] and Fig. 3[link]). Within the layers there are C—H⋯π inter­actions present (Fig. 4[link] and Table 1[link]). The layers are also linked by C—H⋯π inter­actions (Table 1[link]), forming a three-dimensional structure (Fig. 4[link]).

4. Database survey

A search of the Cambridge Structural Database (CSD, V5.37, update November 2015; Groom & Allen, 2014[Groom, C. R. & Allen, F. H. (2014). Angew. Chem. Int. Ed. 53, 662-671.]) using the hexa­hydro­indazole ring system as the main skeleton, revealed the presence of 27 structures. A search for a thia­zole ring linked to an N atom of a pyrazole ring, similar to the situation in the title compound, yielded six hits. One of these structures, 2-(3-phenyl-3,3a,4,5-tetra­hydro-2H-benzo[g]indazol-2-yl)-1,3-thia­zol-4(5H)-one (refcode LUHGAY; Gautam & Chaudhary, 2015[Gautam, D. & Chaudhary, R. P. (2015). Spectrochim. Acta Part A, 135, 219-226.]), resembles the title compound with an indazole ring system linked to a thia­zole ring. The mean plane of the two five-membered rings are inclined to one another by ca 10.05°, similar to the arrangement in mol­ecule A of the title compound.

5. Synthesis and crystallization

The synthesis of the title compound is illustrated in the Scheme. A mixture of thio­semicarbazone (1) (1.5 mmol, 1 eq), ethyl 2-bromo­acetate (0.24 ml, 1.5 mmol) and anhydrous sodium acetate (0.37 g, 4.5 mmol, 3 eq) in absolute ethanol (30 ml) was heated under reflux until the completion of the reaction (1–3 h). The solvent was then evaporated under reduced pressure and the crude product was purified by chromatography on silica gel (230–400 mesh) using hexa­ne/ethyl acetate (90:10) as eluent to give pure indazolic thia­zolidin-4-one in 60% yield as a diastereomeric mixture. Slow evaporation from an ethano­lic solution gives crystals of the pure diastereoisomer of the title compound (2) suitable for crystallographic analysis.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. The C-bound H atoms were included in calculated positions and treated as riding atoms: C—H = 0.96–0.98 Å with Uiso(H) = 1.5Ueq(C-meth­yl) and 1.2Ueq(C) for other H atoms.

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.
