(2SR,4RS)-7-Fluoro-2-exo-(2-furyl)-2,3,4,5-tetra­hydro-1H-1,4-ep­oxy-1-benzazepine, C14H12FNO2, (I), crystallizes with Z′ = 2 in the space group P21/c. A combination of three C—H...O hydrogen bonds and one C—H...N hydrogen bond links the mol­ecules into a complex chain of rings, and pairs of such chains are linked into a tube-like structure by two C—H...π(arene) hydrogen bonds. There are no hydrogen bonds in the structure of racemic (2SR,4RS)-2-exo-(5-bromo-2-thienyl)-7-fluoro-2,3,4,5-tetra­hydro-1H-1,4-epoxy-1-benzazepine, C14H11BrFNOS, (II), while the mol­ecules of (2S,4R)-2-exo-(5-bromo-2-thienyl)-7-trifluoro­meth­oxy-2,3,4,5-tetrahydro-1H-1,4-epoxy-1-benzazepine, C15H14BrF3NO2S, (III), are linked into sheets by a combination of two C—H...O hydrogen bonds and one C—H...π(arene) hydrogen bond. The significance of this study lies in its observation of the wide variation in the patterns of supra­molecular aggregation, consequent upon modest changes in the peripheral substituents.

Comment top

In a continuation of our structural study of 2-substituted 1,4-epoxy-tetrahydro-1-benzazepines (Acosta et al., 2008; Gómez et al., 2008), itself part of a programme to identify structurally novel anti-parasitic compounds with new modes of action to combat both Trypanosoma cruzi and Leishmania chagasi parasites (Gómez et al., 2006; Yépez et al., 2006), we now report the structures of three examples, (I)–(III), carrying heterocylic substituents at position C2 (Figs. 1–3). The synthesis of compounds (I)–(III) involved treating an appropriately substituted 2-allyl-N-(2'-furylmethyl)aniline or 2-allyl-N-(2'-thienylmethyl)aniline with an excess of hydrogen peroxide solution in the presence of catalytic amounts of sodium tungstate.

Under the synthetic and crystallization conditions employed, (I) and (II) both crystallize as racemic mixtures in space group P21/c, where (I) crystallizes with Z' = 2. Compound (III) crystallizes as a single enantiomorph in space group P21 and the configuration at C4 is R, as shown by the Flack x parameter (Flack, 1983). Hence the reference molecules for the racemic compounds were selected to have the R configuration at C4. On this basis, the reference molecules in (I)–(III) all have the S configuration at C2.

The shapes of the heterobicyclic ring systems in (I)–(III), as defined by the ring-puckering parameters (Cremer & Pople, 1975), are all very similar (Table 1). The five-membered rings in (II) and (III) adopt half-chair conformations, for which the ideal puckering angle ϕ is (36k + 18)°, where k represents an integer, while for both independent molecules in (I) the conformations are intermediate between an envelope form, where the ideal value of ϕ is 36k°, and the half-chair form observed in the other examples. The conformations of the six-membered heterocyclic rings are intermediate between a half-chair form, where the idealized values of the ring-puckering angles are θ = 50.8° and ϕ = (60k + 30)°, and an envelope form, where the idealized values are θ = 54.7° and ϕ = 60k°.

The values of the torsion angle N1—C2—C21—C22 in (I)–(III), which defines the orientation of the pendent heterocyclic substituent, have rather similar values in the two independent molecules in (I) [86.7 (3) and 74.5 (3)°], but very different values in (II) [-60.1 (3)°] and (III) [36.6 (4)°], indicative of almost orthogonal orientations for the thienyl groups in these two compounds. There is no obvious simple interpretation of this observation.

Compound (I) crystallizes with Z' = 2, in space group P21/c. There are six independent hydrogen bonds in the crystal structure (Table 2), leading to the formation of a structure of some complexity but which can in fact be readily analysed in terms of simple motifs. Type 1 molecules (containing atom N11), which are related by translation, are linked by a three-centre C—H···(O,N) interaction. The C—H···O and C—H···N components individually generate C(4) and C(5) (Bernstein et al., 1995) chains, while their combination generates a C(4)C(5)[R21(3)] chain of rings running parallel to the [100] direction (Fig. 4). By contrast, the type 2 molecules (containing atom N21), related by translation, are linked only by a C—H···O hydrogen bond, forming a simple C(4) chain parallel to [100]. The two independent molecules are linked within the asymmetric unit by a further C—H···O hydrogen bond, so that the combination of all the C—H···O and C—H···N interactions generates a chain of rings based on an R34(20) motif (Fig. 4). An antiparallel pair of such chains, related to one another by inversion, are then linked by two independent C—H···π(arene) hydrogen bonds to form a complex tubular structure (Fig. 5).

There are no hydrogen bonds of any type in the structure of (II). Instead, the molecules are weakly linked in pairs by a single aromatic ππ stacking interaction to form dimeric units (Fig. 6). The fluoro-substituted aryl rings of the molecules at (x, y, z) and (1 - x, 1 - y, 1 - z) are parallel, with an interplanar spacing of 3.450 (2) Å; the corresponding ring-centroid separation is 3.853 (2) Å, giving a ring offset of 1.716 (2) Å.

In the structure of the trifluoromethoxy analogue, (III), by contrast, there are three hydrogen bonds, two of C—H···O type and one of C—H···π(arene) type (Table 2), and they give rise to a sheet the formation of which is very simply analysed in terms of two simple substructures. Aryl atom C9 in the molecule at (x, y, z) acts as hydrogen-bond donor to atom O14 in the molecule at (-x, 1/2 + y, 1 - z), so linking molecules related by the 21 screw axis along (0, y, 1/2) into a C(5) chain running parallel to the [010] direction. At the same time, thienyl atom C23 at (x, y, z) acts as hydrogen-bond donor to atom O14 in the molecule at (1 + x, y, z), thus generating by translation a C(6) chain running parallel to the [100] direction. The combination of these two chain motifs then generates a sheet parallel to (001) and built from R34(20) rings (Fig. 7). In addition, the substructure along [100] is reinforced by the C—H···π(arene) hydrogen bond, but there are no direction-specific interactions between adjacent sheets.

Experimental top

For each of compounds (I)–(III), to a stirred solution of the appropriately substituted 2-allylaniline (0.10 mol) in methanol (40 ml) was added sodium tungstate dihydrate, Na2WO4.2H2O (5 mol%), followed by 30% aqueous hydrogen peroxide solution (0.30 mol). The resulting mixtures were then stirred at ambient temperature for periods ranging from 18 to 60 h. Each mixture was then filtered and the solvent was removed under reduced pressure. Toluene (50 ml) was added to the solid residue and the resulting solution was heated under reflux for periods ranging from 6 to 8 h. After cooling the solution to ambient temperature, the solvent was removed under reduced pressure and the crude product was purified by chromatography on silica using heptane–ethyl acetate (compositions ranged from 10:1 to 60:1 v/v) as eluent. Crystallization from heptane gave crystals of compounds (I)–(III) suitable for single-crystal X-ray diffraction.

Refinement top

Unique assignments of space groups were made from the systematic absences for compounds (I) and (II), both P21/c. For compound (III), the systematic absences permitted P21 or P21/m as possible space groups; P21 was selected, and confirmed by the subsequent structure analyses. All H atoms were located in difference maps and then treated as riding atoms in geometrically idealized positions, with C—H = 0.95 (aromatic, heteroaromatic and alkene), 0.99 (CH2) or 1.00 Å (aliphatic CH), and with Uiso(H) = 1.2Ueq(C). For compound (III), the correct enantiomorph, having the R configuration at C4, was established by means of the Flack x parameter (Flack, 1983). The reference molecules in (I) and (II) were therefore chosen as those having the R configuration at C4.

Puckering parameters for five-membered rings are defined for the atom sequence O14/N1/C2/C3/C4, apart from compound (I), where Z' = 2 and the atom sequences are Ox14/Nx1/Cx2/Cx3/Cx4 for x = 1 or 2. Puckering parameters for six-membered rings are defined for the atom sequence O14/N1/C9a/C5a/C5/C4, apart from compound (I), where the atom sequences are Ox14/Nx1/Cx9A/Cx5A/Cx5/Cx4 for x = 1 or 2.
