Crystal structures of two triazola-dioxola-benzena­cyclo­nona­phanes

Two dioxala-benzena­cyclo­nona­phanes differ principally by the presence of a pyrrolizine ring system in one and a pyrrolo­thia­zole ring system in the other. In the crystal of the former, mol­ecules are linked via C—H⋯N and C—H⋯O hydrogen bonds, forming sheets parallel to (10) while in the latter, mol­ecules are linked via C—H⋯N, C—H⋯O and C—H⋯S hydrogen bonds, forming slabs parallel to (001).

Abstract

In the title compounds, C₂₅H₂₉BrN₅O₇, (I) [systematic name: (Z)-1⁵-bromo-3²,3²-dimethyl-2¹-nitro-2²,2³,2⁵,2⁶,2⁷,2^7a,3^3a,3⁵,3⁶,3^6a-deca­hydro-2¹ H,6¹ H-4,9-dioxa-2(3,2)-pyrrolizina-6(4,1)-triazola-3(5,6)-furo[2,3-d][1,3]dioxola-1(1,2)-benzena­cyclo­nona­phane], and C₂₄H₂₉N₅O₇S, (II) [systematic name: (Z)-3²,3²-dimethyl-2⁷-nitro-2⁵,2⁶,2⁷,2^7a,3^3a,3⁵,3⁶,3^6a-octa­hydro-2¹ H,2³ H,6¹ H-4,9-dioxa-2(5,6)-pyrrolo­[1,2-c]thia­zola-6(4,1)-triazola-3(5,6)-furo[2,3-d][1,3]dioxola-1(1,2)-benzena­cyclo­nona­phane], the triazole rings adopt almost planar conformations. In (I), the fused pyrrolidine rings adopt envelope conformations with the C atoms opposite the fused N—C bond as the flap in each ring, and their mean planes are inclined to one another by 52.8 (3)°. In (II), the pyrrolidine and thia­zole rings are both twisted on the fused N—C bond, and their mean planes are inclined to one another by 70.8 (2)°. In both (I) and (II), the furan ring adopts an envelope conformation with the adjacent C atom of the macrocycle as the flap. In the crystal of (I), mol­ecules are linked via C—H⋯N and C—H⋯O hydrogen bonds, forming sheets parallel to (10-1), while in (II), mol­ecules are linked via C—H⋯N and C—H⋯O hydrogen bonds, forming helical chains propagating along [010], which are linked via C—H⋯S hydrogen bonds, forming slabs parallel to (001).

Chemical context  

Triazoles and their derivatives are of great importance in medicinal chemistry and can be used for the synthesis of many heterocyclic compounds with different biological activities such as anti­viral, anti­bacterial, anti­fungal (Mange et al., 2013 ▸), anti­cancer (Singhal et al., 2011 ▸), anti­tuberculosis, anti­convulsant, anti­depressant (Sahin et al., 2012 ▸) and anti-inflammatory activities. They have been reported to be inhib­itors of glycogen synthase kinase-3, antagonists of GABA receptors, agonists of muscarine receptors and have been shown to possess anti-HIV-1, cytotoxic, anti­histaminic and anti­proliferative activities (Pokhodylo et al., 2013 ▸). Triazoles are stable to acid and basic hydrolysis and reductive and oxidative conditions because of their high aromatic stabilization. In addition, this heterocycle has a high dipole moment and might participate in hydrogen-bond formation as well as in dipole–dipole and π-stacking inter­actions (Pertino et al., 2013 ▸).

Structural commentary  

The molecular structures of compounds (I) and (II) are illustrated in Figs. 1 ▸ and 2 ▸, respectively. The triazole rings (A = N3–N5/C22/C23) adopt almost planar conformations in both compounds. In compound (I), the pyrrolidine rings (D = N1/C11–C13/C7 and E = N1/C8–C11) and the furan ring (B = O3/C15/C19/C20/C14) have envelope conformations with the maximum deviations from the respective mean planes of 0.465 (5) Å for atom C13, 0.490 (7) Å for C9 and 0.500 (4) Å for C14. The dioxalane ring (C = O4/C15/C19/O5/C16) has a twisted conformation on bond O5—C15. The mean planes of rings B and C are inclined to one another by 70.0 (3)°, and the mean planes of rings D and E are inclined to one another by 52.8 (3)°.

The mol­ecular structure of compound (II), showing the atom labelling. Displacement ellipsoids are drawn at the 30% probability level. H atoms are omitted for clarity.

In compound (II), the pyrrolidine (D) and thia­zole rings (E = N1/C8/S9/C10/C11) have twist conformations on bond N1—C11. The furan and dioxolane rings (B and C) adopt envelope conformations with maximum deviations from the mean planes of 0.631 (3) Å for atom C14 and 0.319 (4) Å for C16. The mean planes of rings B and C are inclined to one another by 68.5 (2)° and the mean planes of rings D and E are inclined to one another by 70.8 (2)°. This latter dihedral angle is much larger than that in compound (I), cf. 52.8 (3)°.

In compound (I), the triazole ring (A) makes dihedral angles of 74.0 (3), 65.8 (3) and 65.8 (3)° with the mean planes of rings B and D and the benzene ring (C1–C6), respectively. The corresponding dihedral angles in compound (II) are 51.9 (2), 37.1 (2) and 60.9 (2)°, respectively. The most notable differences between the compounds involve dihedral angles A/B and A/D; 74.0 (3) and 65.8 (3), respectively, for (I), and 51.9 (2) and 37.1 (2)°, respectively, for (II).

Synthesis and crystallization  

Compound (I): A solution of 5-bromo-2-(2-{4-[({(3aS,6R,6aS)-2,2-dimethyl-5-[(Z)-2-nitro­vin­yl]tetra­hydro­furo[2,3-d][1,3]di­oxol-6-yl}­oxy)meth­yl]-1H-1,2,3-triazol-1-yl}eth­oxy)benzalde­hyde (1 mmol) and proline (1.5 mmol) was refluxed in dry aceto­nitrile (50 ml) under a nitro­gen atmosphere for 9 h. After completion of the reaction, as indicated by TLC, the aceto­nitrile was evaporated under reduced pressure. The crude product was purified by column chromatography using hexa­ne/EtOAc (3:7) as eluent (yield 75%). After purification the compound was recrystallized in CHCl₃ by slow evaporation yielding colourless block-like crystals.

After completion of reaction, as indicated by TLC,the aceto­nitrile was evaporated under reduced pressure. The crude product was purified by column chromatography using hexa­ne/EtOAc (4:6) as eluent (yield 75%). After purification the compound was recrystallized in CHCl₃ by slow evaporation yielding colourless block-like crystals.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
